Cronología

  • 00:00:00 - 00:05:00

    Hola a todos, mi nombre es Irvin, también conocido como Cobumen. En esta serie de videos, abordaremos el sistema operativo Microsoft Windows Server desde la perspectiva del soporte técnico. En esta primera parte, nos centraremos en Active Directory, usuarios y equipos. En los próximos videos, veremos DHCP y DNS. La idea es proporcionar una forma comprensible de utilizar estos sistemas para ser eficaces en su trabajo.

  • 00:05:00 - 00:10:00

    Iniciamos con una máquina virtual configurada para Windows Server y Windows 10. En Active Directory, se gestionan usuarios y computadoras. Normalmente, no se accede directamente al servidor, sino que se usan herramientas administrativas de Windows, que permiten gestionar remotamente el servidor desde una máquina Windows 10 y trabajar con Active Directory, DHCP y DNS.

  • 00:10:00 - 00:15:00

    Se explica qué es Active Directory: un directorio que contiene información sobre usuarios y computadoras, similar a una libreta de teléfonos. Comenzamos creando usuarios y computadoras en Active Directory. Mostramos cómo instalar herramientas administrativas en una computadora Windows 10 para gestionar un servidor remotamente.

  • 00:15:00 - 00:20:00

    Se detalla el proceso para agregar una computadora a un dominio. Creamos un nombre de computadora en Windows 10 y lo unimos a un Active Directory dentro de un dominio. Al unirse al dominio, la computadora es controlada por dicho dominio, lo que permite gestionar seguridad, permisos y despliegue de software.

  • 00:20:00 - 00:25:00

    Tras la unión al dominio, comprobamos la conexión DNS en la computadora Windows 10 y verificamos con la dirección IP. Se muestra cómo las computadoras dentro del dominio pueden ser gestionadas remotamente usando herramientas de administración, facilitando tareas como ver logs de eventos o gestionar el disco.

  • 00:25:00 - 00:30:00

    Explicamos cómo en un entorno de negocio, los ‘grupos’ determinan las políticas que aplican restricciones o instalan software en las computadoras. Ejemplificamos añadiendo una computadora a un grupo que podría instalar Chrome automáticamente y cómo funcionan las políticas de seguridad y membresía.

  • 00:30:00 - 00:35:00

    Se retiró una computadora del dominio para demostrar cómo se marca como offline en Active Directory. Explicamos que computadoras en un dominio son manejadas mediante herramientas de administración, y cómo una computadora puede ser unida a un dominio sin predefinir su nombre en Active Directory.

  • 00:35:00 - 00:40:00

    Creamos un nuevo usuario en Active Directory, Kopumann, otorgándole privilegios de administrador mediante una política de grupo de soporte técnico. Exploramos cómo las políticas de grupo facilitan la administración al automatizar los privilegios y software que se aplican a los usuarios, destacando la conveniencia de gestionar grupos.

  • 00:40:00 - 00:45:00

    Se muestra cómo Active Directory puede gestionar políticas a nivel de dominio que agregan usuarios a grupos de seguridad, permitiendo así el acceso administrativo en sistemas individuales. Este enfoque facilita asignar y replicar permisos a usuarios sin intervenciones manuales en cada equipo.

  • 00:45:00 - 00:50:00

    Entramos a DHCP, la segunda parte, creado previamente en Windows 10 permite gestionar remotamente. Explicamos qué es un ‘rango de IP’ y cómo se definen límites de direcciones disponibles para dispositivos bajo server DHCP. Al definir ‘reservas’, asignamos IP fijas basadas en direcciones MAC de dispositivos como impresoras.

  • 00:50:00 - 00:55:00

    Mostramos cómo añadir a reservas DHCP dispositivos como impresoras o cámaras IP, especificando su dirección MAC para que reciban una dirección IP específica. Resaltamos la importancia de organizar las reservas y sus usos en un entorno de red, asegurando así la conectividad óptima de dispositivos esenciales.

  • 00:55:00 - 01:00:00

    Para optimizar la administración de la red, se explica la importancia de no borrar reservas DHCP a menos que sea necesario. Las direcciones IP dinámicas pueden resetearse en situaciones de conectividad, mientras que las reservas aseguran configuraciones persistentes esenciales para dispositivos críticos.

  • 01:00:00 - 01:05:00

    Introducimos DNS y su rol en traducir nombres de dominio a direcciones IP y viceversa. Facilitamos la comprensión del porqué www.exampe.com solo apunta a una IP gracias al DNS, y cómo esto es esencial tanto para Internet como para redes locales. Se detalla cómo DNS cubre direcciones locales usando registros A.

  • 01:05:00 - 01:10:00

    Sección DNS continúa con exploraciones sobre la importancia de los registros A dentro de un dominio, que ayudan a mapear nombres a direcciones IP permitiendo la gestión de recursos locales sin manipular directamente las IP, y describimos cómo agregar registros A manualmente cuando es necesario.

  • 01:10:00 - 01:15:00

    DNS también gestiona zonas de búsqueda inversa que enlazan direcciones IP a nombres de dominio, útil por ejemplo en resolución inversa de IP a nombres. En un entorno corporativo, típicamente se gestionan registros de encubrimiento de direcciones IP duplicadas o problemáticas soluciones de replicación manual.

  • 01:15:00 - 01:23:29

    Finalmente, se resalta la relevancia del DNS para la resolución y gestión de sistemas en grandes redes, al facilitar administración y solución de problemas. Complementa la serie de videos proporcionando conocimientos prácticos que prepara a los técnicos para un entorno real, dirigiendo hacia el futuro contenido sobre soporte técnico.

  • 00:00:00
    hello everyone my name is Irvin also
  • 00:00:02
    known as cobumen today's session is
  • 00:00:04
    going to be about Microsoft Windows
  • 00:00:07
    Server operating system this is going to
  • 00:00:09
    be from the point of view of tech
  • 00:00:11
    support what I'm going to show you is
  • 00:00:13
    the way it's set up in my current job
  • 00:00:17
    and for those Reasons I'm going to teach
  • 00:00:19
    it in such a way where it's easy to
  • 00:00:20
    understand so that way you can
  • 00:00:22
    familiarize yourself with it and that
  • 00:00:24
    way you can use it and be effective at
  • 00:00:26
    your job so there's going to be three
  • 00:00:28
    parts of this and if you don't want to
  • 00:00:30
    miss any of them you might want to
  • 00:00:31
    subscribe and also turn on notifications
  • 00:00:33
    for this so the first part is going to
  • 00:00:36
    be about ad also known as active
  • 00:00:38
    directory users and computers this video
  • 00:00:41
    is going to concentrate on that and the
  • 00:00:43
    second video in the future is going to
  • 00:00:45
    be about DHCP Dynamic host configuration
  • 00:00:49
    protocol and how that ties in with ad
  • 00:00:51
    and the third part is going to be about
  • 00:00:54
    DNS the main name system so we're going
  • 00:00:58
    to start from the top all the way way to
  • 00:01:00
    the bottom and all of this is going to
  • 00:01:02
    make sense I promise all of my videos
  • 00:01:05
    are really easy to follow and this is
  • 00:01:07
    why I make them in such way that anybody
  • 00:01:10
    can understand them even if you have no
  • 00:01:13
    experience when it comes to tech support
  • 00:01:15
    alright let's get into it and let's
  • 00:01:18
    start with actor directory users and
  • 00:01:21
    computers alright here we are this is a
  • 00:01:24
    virtual machine set up for Windows
  • 00:01:27
    server and also just for Windows 10 on
  • 00:01:29
    the right here is just a Windows 10
  • 00:01:31
    machine and on the left here is server
  • 00:01:34
    operating system alright so in here this
  • 00:01:38
    is where we're going to do most of our
  • 00:01:40
    work but we will go into the Windows 10
  • 00:01:42
    machine over here just so we can
  • 00:01:44
    correlate and so I can show you what is
  • 00:01:46
    going on with the active directory users
  • 00:01:48
    and accounts now if you are working for
  • 00:01:52
    a company that allows you access to this
  • 00:01:55
    you won't necessarily have a direct
  • 00:01:56
    access to the server itself like this
  • 00:01:59
    meaning that you remotely log into it
  • 00:02:02
    and you have Windows desktop experience
  • 00:02:05
    like this you would probably do it with
  • 00:02:09
    a install of what is called Windows
  • 00:02:11
    administrative tools you see how they
  • 00:02:13
    show up here on the left side you can
  • 00:02:15
    install this as you can think of it as a
  • 00:02:19
    plug-in an extension of your Windows 10
  • 00:02:21
    machine so you can see all of these
  • 00:02:23
    things that are part of Windows
  • 00:02:25
    administrative tools this does not come
  • 00:02:28
    pre-installed with Windows 10 however
  • 00:02:30
    you can install it so that way you can
  • 00:02:33
    remotely access This Server so here it
  • 00:02:36
    is for example here is actor directory
  • 00:02:38
    users and computers what is the other
  • 00:02:40
    thing we can concentrate on DHCP and DNS
  • 00:02:43
    in the future videos so you can have
  • 00:02:45
    this module these tools installed over
  • 00:02:48
    here on the Windows 10 machine and for
  • 00:02:51
    those reasons you can simply go to
  • 00:02:53
    Google
  • 00:02:55
    in your Windows 10 machine type in
  • 00:02:58
    Google
  • 00:03:00
    .com and type in download
  • 00:03:03
    windows
  • 00:03:06
    administrative tools
  • 00:03:09
    like this
  • 00:03:11
    and it says here this is directly from
  • 00:03:13
    Microsoft Remote server Administration
  • 00:03:14
    tools for Windows 10. so if you click on
  • 00:03:17
    here it will take you to a download page
  • 00:03:20
    where you can download it and here it is
  • 00:03:23
    you simply select download and then you
  • 00:03:26
    install it pick the operating system
  • 00:03:28
    version that you have if you have a
  • 00:03:29
    64-bit you select 64-bit select next
  • 00:03:33
    it's going to download it and then once
  • 00:03:36
    it's downloaded here in a second we're
  • 00:03:38
    going to install it
  • 00:03:41
    and as long as your computer is part of
  • 00:03:44
    the same domain it should what it should
  • 00:03:47
    let you install and control the same
  • 00:03:49
    thing so you just click accept while
  • 00:03:52
    you're installing it and it's just going
  • 00:03:53
    to take a little bit here to install
  • 00:03:55
    Windows administrative tools so that way
  • 00:03:58
    you can remotely access them of course
  • 00:04:01
    when you start doing tech support this
  • 00:04:03
    is one of the first things you would be
  • 00:04:05
    able to do or it might be pre-installed
  • 00:04:07
    with the operating system image that you
  • 00:04:10
    get when you start to work for that
  • 00:04:13
    company so while that's installing on
  • 00:04:15
    our Windows 10 machine Let's Talk About
  • 00:04:17
    80 as in actor directory users and
  • 00:04:20
    computers what is active directory users
  • 00:04:23
    and computers if you concentrate on the
  • 00:04:26
    word here directory and users you can
  • 00:04:29
    figure this out easily so directory
  • 00:04:32
    think of it as just a directory as in
  • 00:04:34
    list of people sort of like a phone book
  • 00:04:36
    you look up users users are basically
  • 00:04:40
    people like you and me or anybody else
  • 00:04:42
    who uses computers get it users right
  • 00:04:45
    and it also has the information about
  • 00:04:48
    computers they're also part of that
  • 00:04:51
    directory or that phone book right so
  • 00:04:54
    this is just a simple correlation to get
  • 00:04:56
    your understanding what is active
  • 00:04:58
    directory users and computers to begin
  • 00:05:00
    with so now that we have a rough idea
  • 00:05:03
    what ad is about we're going to show you
  • 00:05:05
    this in action we're going to go inside
  • 00:05:07
    of AD we're going to create users and
  • 00:05:09
    computers and then we're going to join
  • 00:05:11
    computers to the actor directory there
  • 00:05:13
    are a couple of different ways of going
  • 00:05:15
    about this again I'm going to
  • 00:05:16
    concentrate on the way it's set up at my
  • 00:05:18
    current job is because it's fresh in my
  • 00:05:21
    mind and that's just the way it's easier
  • 00:05:24
    for me to describe it alright so we have
  • 00:05:26
    installed Windows administrative tools
  • 00:05:30
    on our Windows 10 computer so this is
  • 00:05:32
    our regular computer we're going to be
  • 00:05:33
    using again the point of this is so that
  • 00:05:36
    we can access the server remotely so we
  • 00:05:39
    don't have access necessarily nor or do
  • 00:05:42
    we want to constantly log into the
  • 00:05:44
    server operating system this way we can
  • 00:05:47
    remotely access it so here it is Windows
  • 00:05:49
    administrative tools actor directory
  • 00:05:51
    users accounts so this is Windows 10
  • 00:05:53
    machine and here is the server which has
  • 00:05:56
    the same thing all right well let's just
  • 00:05:58
    dial for the server and then we're going
  • 00:06:00
    to go from there so here we go active
  • 00:06:02
    directory users and computer so under
  • 00:06:04
    Windows administrator tools open up
  • 00:06:07
    active directory users and computers so
  • 00:06:10
    the first thing you would see here is
  • 00:06:11
    just says newdomain.com and the reason I
  • 00:06:14
    named it like that just so that you know
  • 00:06:16
    that this computer here is in this
  • 00:06:18
    server here that we're controlling is a
  • 00:06:22
    domain right and every computer that's
  • 00:06:24
    joined that domain is part of that
  • 00:06:27
    domain so in you can correlate this with
  • 00:06:31
    like a country you can assume that a
  • 00:06:33
    domain a computer domain is like a
  • 00:06:35
    country and that country controls
  • 00:06:37
    everything that's inside of that country
  • 00:06:39
    in this case the main is a for example a
  • 00:06:43
    country and that country is going to
  • 00:06:45
    control all the computers and users that
  • 00:06:48
    are part of that domain
  • 00:06:51
    okay and first thing we're going to
  • 00:06:53
    start with is actually computers so if
  • 00:06:55
    you just you know expand this and you
  • 00:06:58
    see these folders right you can consider
  • 00:07:00
    them folders but they're actually also
  • 00:07:02
    known as
  • 00:07:03
    ous organizational units but they're
  • 00:07:06
    folders right I mean let's be honest but
  • 00:07:08
    if you hear somebody talk about
  • 00:07:11
    OU's this is what they're talking about
  • 00:07:13
    they're talking about organizational
  • 00:07:15
    units and you can add more and you can
  • 00:07:17
    add new ones this and that to here but
  • 00:07:20
    we're going to stick with the default
  • 00:07:22
    ones because this is going to make it
  • 00:07:24
    easier to understand and if there is a
  • 00:07:27
    need and if people are interested in
  • 00:07:29
    more more advanced videos we can
  • 00:07:31
    certainly expand on that so let's start
  • 00:07:33
    with computers like I said and there are
  • 00:07:35
    a couple of ways of controlling a
  • 00:07:37
    computer that's on a domain well why
  • 00:07:40
    would you do this to begin with well
  • 00:07:42
    because when you add a computer to a
  • 00:07:45
    domain or in this case part of a domain
  • 00:07:48
    which is actor directory when you add a
  • 00:07:51
    computer inside of this folder it's
  • 00:07:52
    going to become part of that directory
  • 00:07:55
    right it's going to be part of their
  • 00:07:56
    directory and the point of it is so that
  • 00:07:58
    you can control it you can manage it so
  • 00:08:01
    things like security
  • 00:08:03
    restrictions permissions and software
  • 00:08:07
    deployments it also tells you where the
  • 00:08:11
    computer is on the network itself for
  • 00:08:14
    example you can put description of it
  • 00:08:16
    and this and that okay let's get into it
  • 00:08:17
    before I get more confusing so I'm just
  • 00:08:19
    going to right click the computer here
  • 00:08:21
    where it says computers folder and I'm
  • 00:08:23
    going to select new computer and then
  • 00:08:26
    I'm going to create a new computer name
  • 00:08:30
    you can do the same thing if you right
  • 00:08:31
    click inside of the white area as long
  • 00:08:34
    as you have computer selected so I'm
  • 00:08:36
    going to name it
  • 00:08:38
    work
  • 00:08:41
    Dash
  • 00:08:43
    zero zero
  • 00:08:45
    one so this is just a naming scheme just
  • 00:08:48
    in case there is a zero zero two zero
  • 00:08:51
    zero three four ten twenty hundred right
  • 00:08:54
    so this is just the point of that and we
  • 00:08:56
    can just leave all of this as default
  • 00:08:57
    we're just going to click ok
  • 00:08:59
    so did we add a computer to a to an
  • 00:09:04
    active directory right now no not yet
  • 00:09:07
    all we've done is create a name for that
  • 00:09:10
    computer so there's a different way of
  • 00:09:12
    doing this as well it just depends on
  • 00:09:15
    how you prefer to do it and sometimes
  • 00:09:17
    you want to do it this way and sometimes
  • 00:09:19
    you want to do it the other way the
  • 00:09:21
    other way is literally just going to
  • 00:09:24
    that computer that you want to join it
  • 00:09:26
    to a domain and as long as it's on the
  • 00:09:29
    same network you can create that name on
  • 00:09:33
    that computer and then add it in here as
  • 00:09:36
    well so but let's start with this we're
  • 00:09:39
    going to start with a pre-created
  • 00:09:41
    hostname or a computer name or a
  • 00:09:44
    workstation name however you want to
  • 00:09:45
    call it I like to call them host names
  • 00:09:49
    so we've got one that we've pre-made now
  • 00:09:52
    we're going to join a Windows 10 machine
  • 00:09:54
    using this name to this actor directory
  • 00:09:58
    into this domain we're going to join it
  • 00:10:00
    and we're going to use that name okay so
  • 00:10:03
    here's our Windows 10 machine and by the
  • 00:10:06
    way we can't use our tools our admin
  • 00:10:09
    tools until we are connected to the same
  • 00:10:13
    domain because we need to use the main
  • 00:10:16
    administrator privileges in order to use
  • 00:10:18
    actor directory users on a remote
  • 00:10:21
    computer right
  • 00:10:23
    okay I hope you're still with me so
  • 00:10:25
    anyways let's get back to this and you
  • 00:10:27
    can add a computer or join a computer to
  • 00:10:30
    a domain if you go to system
  • 00:10:34
    properties
  • 00:10:36
    Windows 10 just likes to come up with
  • 00:10:39
    the about and here is just one way of
  • 00:10:41
    going about it if you were to rename
  • 00:10:43
    this PC it's not enough so this is the
  • 00:10:45
    about section Windows 10 if I click
  • 00:10:47
    rename this PC and let's say I name it
  • 00:10:51
    whatever we just put in their work
  • 00:10:54
    Dash zero zero zero one it's not going
  • 00:10:58
    to add it to the domain at all all it is
  • 00:11:00
    is just renaming the computer so this is
  • 00:11:03
    not going to work so what we have to do
  • 00:11:05
    is join it to a domain so if you scroll
  • 00:11:07
    down and go to Advanced system settings
  • 00:11:10
    and this is why I was starting to type
  • 00:11:13
    system properties mainly because I'm
  • 00:11:15
    used to Windows 7 for a long time I've
  • 00:11:18
    been around for a while doing tech
  • 00:11:20
    support and Windows 10 they like to hide
  • 00:11:22
    things and things are not different
  • 00:11:24
    anyways I digress here's system
  • 00:11:26
    properties if you go to computer name
  • 00:11:28
    which is the first stab and then click
  • 00:11:31
    on change on the bottom here where it
  • 00:11:32
    says this to rename this computer or
  • 00:11:34
    change its domain or work group Click
  • 00:11:37
    Change
  • 00:11:38
    here is where we're going to change the
  • 00:11:41
    name and add it to the domain at the
  • 00:11:44
    same time so what was the name again
  • 00:11:45
    work
  • 00:11:47
    Dash zero zero zero one so we're going
  • 00:11:51
    to use a predetermined preset name
  • 00:11:54
    that's already existing on actor
  • 00:11:57
    directory and then we're going to assign
  • 00:11:59
    it to this computer
  • 00:12:02
    so this computer again there's another
  • 00:12:04
    way of doing it which we're going to do
  • 00:12:06
    next after after we're done with this so
  • 00:12:08
    let's go back to the server just to
  • 00:12:09
    double check and look it says work dash
  • 00:12:12
    zero zero zero one and that's what we
  • 00:12:15
    have on our Windows 10 machine and down
  • 00:12:18
    here we have to change the member off
  • 00:12:21
    meaning we want to make it a member of
  • 00:12:24
    domain member of domain so what do I
  • 00:12:27
    type in here
  • 00:12:29
    well we're gonna have to type in the
  • 00:12:31
    name of the domain remember so remember
  • 00:12:33
    we talked about this it's a domain is
  • 00:12:36
    basically like a country and everything
  • 00:12:38
    within that country within that domain
  • 00:12:40
    is being controlled by that domain
  • 00:12:43
    regardless of which aspects are present
  • 00:12:47
    there in this case the aspect of control
  • 00:12:49
    is actor directory users and computers
  • 00:12:52
    so in this case we need to add the
  • 00:12:55
    computer to the newdomain.com so this is
  • 00:12:58
    what we're going to have to type in
  • 00:13:02
    newdomain.com and you're gonna need
  • 00:13:05
    administrator privileges for that domain
  • 00:13:09
    to in order to add this computer so you
  • 00:13:12
    need permission you need to be allowed
  • 00:13:14
    to add this computer to a new domain so
  • 00:13:16
    when I click OK it's going to take a bit
  • 00:13:18
    and it's going to ask for the
  • 00:13:20
    credentials for that domain so it says
  • 00:13:22
    computer name the main changes enter the
  • 00:13:25
    name and the passport for an account
  • 00:13:27
    with permission to join the domain so
  • 00:13:30
    I need
  • 00:13:33
    administrator account which is under
  • 00:13:35
    users here
  • 00:13:37
    that will allow me to add this computer
  • 00:13:40
    to this domain so other users like me
  • 00:13:43
    and you and everybody else I need to
  • 00:13:45
    have that login information from any of
  • 00:13:47
    these that are in here luckily I have
  • 00:13:50
    administrator login right here so which
  • 00:13:52
    is what I'm going to use so let's go
  • 00:13:55
    back to computers folder here just so we
  • 00:13:57
    can keep track and I'm going to back to
  • 00:13:59
    the Windows 10 machine
  • 00:14:01
    I'm going to type in my login ID
  • 00:14:04
    administrator and I'm going to use my
  • 00:14:07
    password for the administrator
  • 00:14:10
    that's allowed to that's part of the
  • 00:14:12
    domain that's going to allow this
  • 00:14:15
    computer to join the domain here it is
  • 00:14:17
    welcome to
  • 00:14:18
    newdomain.com and we're going to have to
  • 00:14:21
    reboot the computer for changes that
  • 00:14:23
    take effect that it'll tell you here
  • 00:14:24
    changes will take effect after you
  • 00:14:26
    restart the computer so we're going to
  • 00:14:28
    restart it right away all right so here
  • 00:14:31
    we are
  • 00:14:33
    we are you know we have rebooted the
  • 00:14:36
    computer now it should be the part of
  • 00:14:38
    the remain I don't know if you noticed
  • 00:14:39
    but my login ID was there there was
  • 00:14:42
    computer one we're gonna change that
  • 00:14:44
    we're gonna actually use a domain login
  • 00:14:46
    now that we are joined into a domain so
  • 00:14:50
    let's double check a couple of different
  • 00:14:52
    things so let's go to command line just
  • 00:14:54
    to prove that this was done we're going
  • 00:14:57
    to do ip config forward slash all and
  • 00:15:02
    the reason I'm doing this because I want
  • 00:15:04
    you to see that DNS is added and it's
  • 00:15:08
    part of the new domain it says here
  • 00:15:10
    hostname here we go hostname right here
  • 00:15:13
    so this is the computer name now work
  • 00:15:15
    zero zero zero one primary DNS
  • 00:15:19
    suffixesnewdomain.com and I just want
  • 00:15:21
    you to see here that DNS is listed there
  • 00:15:24
    as well as ATT local which is just so I
  • 00:15:27
    can have access to the internet and it's
  • 00:15:29
    newdomain.com again we're going to talk
  • 00:15:32
    about DNS here
  • 00:15:34
    um in in the future video this is just
  • 00:15:36
    the first part of it that I'm going to
  • 00:15:38
    explain why this here is important
  • 00:15:40
    otherwise if we didn't have access to
  • 00:15:43
    this DNS server we wouldn't have been
  • 00:15:46
    able to add this computer to this domain
  • 00:15:48
    at all it would not work because it
  • 00:15:50
    would not be able to connect anyways
  • 00:15:52
    that's in the future video
  • 00:15:54
    so we're going to go to about your PC
  • 00:15:57
    again
  • 00:15:58
    and I'm gonna see that this computer is
  • 00:16:01
    now added to the domain and it says here
  • 00:16:03
    device name you know yeah I don't like
  • 00:16:06
    how they keep changing what they want to
  • 00:16:08
    call it hostname device workstation PC
  • 00:16:11
    whatever it's the same thing anyways
  • 00:16:13
    it's work work zero zero zero one and we
  • 00:16:17
    can see the full device name is work
  • 00:16:18
    zero zero
  • 00:16:20
    one dot newdomain.com why because now
  • 00:16:23
    this computer is joined this new domain
  • 00:16:26
    and this is how domain sees it and this
  • 00:16:29
    is how it's recognized on the network as
  • 00:16:33
    such when it comes to managing a part of
  • 00:16:36
    it I mean it still works zero zero zero
  • 00:16:38
    one on the network on the physical
  • 00:16:40
    network but when it comes to the domain
  • 00:16:41
    and what controls it
  • 00:16:44
    it's this is how it's seen by the domain
  • 00:16:46
    and then if we scroll down here and go
  • 00:16:49
    to the advanced system settings and go
  • 00:16:52
    back to computer name we can see that
  • 00:16:54
    this has applied as well
  • 00:16:57
    now we can add another computer there's
  • 00:16:59
    a different way to do it so we don't
  • 00:17:01
    have to create a hostname ahead of time
  • 00:17:03
    so but let me just show you what
  • 00:17:06
    happened here since we've added this
  • 00:17:07
    computer to the new domain so we're
  • 00:17:09
    going to go back to our server and this
  • 00:17:12
    is instant I have not edited or anything
  • 00:17:14
    made any changes this is just me live so
  • 00:17:17
    I'm going to right click this computer
  • 00:17:19
    well first of all you can see that this
  • 00:17:23
    computer is active if this this icon
  • 00:17:26
    here was a little computer icon if I was
  • 00:17:29
    to remove this Windows 10 that we've
  • 00:17:32
    just added if I was to remove it this
  • 00:17:34
    icon would have a down arrow pointing
  • 00:17:36
    down that it's it's not online so we're
  • 00:17:40
    just going to click right click it then
  • 00:17:41
    we're going to go to properties and I'm
  • 00:17:43
    just going to show you that we see the
  • 00:17:45
    same thing here as we saw on the Windows
  • 00:17:47
    10 machine right it says
  • 00:17:48
    work00.01.newdomain.com
  • 00:17:53
    so before we and I the next thing I want
  • 00:17:55
    to talk about which is important for
  • 00:17:57
    somebody who starts to work for
  • 00:17:59
    companies they is a member of this is
  • 00:18:01
    the big part of controlling the computer
  • 00:18:03
    itself but let me just show you another
  • 00:18:06
    cool thing that you can do now that
  • 00:18:07
    we've added this computer and remember I
  • 00:18:10
    just created a name and it wasn't
  • 00:18:12
    connected until we went to that Windows
  • 00:18:14
    10 machine and do it and added it
  • 00:18:16
    manually if I right click and then
  • 00:18:19
    select manage we can now manage that
  • 00:18:22
    remote computer this is this is what's
  • 00:18:24
    going on here look so these are things
  • 00:18:27
    we can do we can remotely do uh use
  • 00:18:31
    Event Viewer where we can view some
  • 00:18:33
    windows logs if we want like system logs
  • 00:18:36
    let's say there are some issues with
  • 00:18:37
    this computer all we have to do is just
  • 00:18:40
    look up this computer
  • 00:18:42
    and matter of fact let's do that the way
  • 00:18:45
    you do it is just by right click find so
  • 00:18:48
    make sure that you have the correct
  • 00:18:51
    domain selected right so it's new domain
  • 00:18:54
    we're going to search what we're going
  • 00:18:55
    to find but we're going to search what
  • 00:18:57
    we're going to search inside of
  • 00:18:58
    newdomain.com and you'll make sure they
  • 00:19:01
    change this to computers right make sure
  • 00:19:04
    you change this computers if you leave
  • 00:19:06
    it at users where you're looking for
  • 00:19:07
    users right so we're searching for a
  • 00:19:09
    computer I'm just going to type in
  • 00:19:11
    partial partial name is going to click
  • 00:19:13
    work and here it is here's our work
  • 00:19:16
    uh00.1 station and if I right click it I
  • 00:19:20
    can go to manage here we are now
  • 00:19:23
    managing that computer again when it
  • 00:19:25
    comes to these things that you see here
  • 00:19:27
    so you know we can look at the device
  • 00:19:29
    manager well we'll have to make some
  • 00:19:31
    adjustments here but potentially we can
  • 00:19:34
    look at the device manager Event Viewer
  • 00:19:36
    Disk Management here it's going to take
  • 00:19:38
    it there it is Disk Management here so
  • 00:19:40
    this is the remote computer now this
  • 00:19:43
    this is the same thing thing that we can
  • 00:19:46
    do if we were to connect remotely to a
  • 00:19:49
    computer so here's computer management
  • 00:19:50
    and if we do this as long as it's part
  • 00:19:52
    of the same network we could potentially
  • 00:19:55
    do this we can do connect to another
  • 00:19:57
    computer right and then you have to type
  • 00:20:00
    in work uh work dash
  • 00:20:03
    zero zero zero one we can click browse
  • 00:20:06
    and we can see you know we can do it
  • 00:20:08
    like that or we can just type in work
  • 00:20:11
    sorry I'm doing it twice I apologize
  • 00:20:15
    work one and here it is we're connected
  • 00:20:17
    the same way this is the same thing as
  • 00:20:19
    me just simply right clicking and manage
  • 00:20:22
    right so let me just kind of do this
  • 00:20:26
    here this computer management is present
  • 00:20:28
    on every computer this is present on
  • 00:20:30
    every computer so if you type in
  • 00:20:33
    computer management you can connect to
  • 00:20:36
    other computers right right now this is
  • 00:20:38
    just local but if I want to connect to
  • 00:20:40
    another computer and or for example
  • 00:20:42
    let's do browse this time work
  • 00:20:45
    Dash zero zero one
  • 00:20:48
    right and do all of this you see how it
  • 00:20:50
    found it click OK click OK and now I'm
  • 00:20:54
    you know managing the remote computer
  • 00:20:56
    instead of doing all of this see how
  • 00:20:58
    it's confusing right
  • 00:21:00
    we can just go to active directory
  • 00:21:03
    find that computer
  • 00:21:06
    you know work
  • 00:21:09
    just right click and manage so it's very
  • 00:21:13
    useful when you're managing multiple
  • 00:21:15
    multiple computers
  • 00:21:17
    okay so that's cool and uh let's talk
  • 00:21:20
    about the next thing here and that is
  • 00:21:22
    members off so if I right click this
  • 00:21:24
    computer and go to properties and go to
  • 00:21:28
    members of what this talks about is
  • 00:21:31
    basically computer permissions you can
  • 00:21:33
    set up what they call the group policy
  • 00:21:36
    objects these Group Policy objects can
  • 00:21:40
    have uh preset the rules instructions or
  • 00:21:44
    if you want to call it programming they
  • 00:21:46
    can put restrictions on the computer for
  • 00:21:49
    example like for example you can block
  • 00:21:51
    certain websites you can block certain
  • 00:21:54
    you know folders from being viewed you
  • 00:21:57
    can put a lot of restrictions on the
  • 00:22:00
    computer if that's what you wanted to do
  • 00:22:02
    you can also deploy software so if you
  • 00:22:06
    can well first of all let's do uh let's
  • 00:22:09
    do one uh when it comes to group policy
  • 00:22:12
    Security Group Policy is what it's
  • 00:22:14
    called right let's gonna we're gonna add
  • 00:22:16
    one I have one that it's already made
  • 00:22:18
    and it's for our group that's called for
  • 00:22:20
    HR so I'm just going to type in HR so
  • 00:22:22
    again I went to add and I'm going to
  • 00:22:26
    make this computer part of HR I'm just
  • 00:22:28
    going to click check name this basically
  • 00:22:30
    just tells me that it actually found it
  • 00:22:32
    and it won't work if it doesn't find it
  • 00:22:34
    then I'm going to click ok
  • 00:22:36
    so this group
  • 00:22:39
    is has
  • 00:22:42
    certain aspects of it that are going to
  • 00:22:45
    place either restrictions on this
  • 00:22:47
    computer or they're going to install
  • 00:22:50
    software that's part of this group so
  • 00:22:53
    that's the only thing I want you to kind
  • 00:22:55
    of consider here so what happens is if
  • 00:22:59
    you want to install new software for
  • 00:23:01
    example onto this computer you can do so
  • 00:23:03
    by adding a group policy object to it
  • 00:23:07
    making it member of that group policy of
  • 00:23:10
    their group that receives specific
  • 00:23:12
    software so let's say you have a group
  • 00:23:15
    policy object that installs Chrome you
  • 00:23:17
    can just type in Chrome and then check
  • 00:23:19
    name and it's going to find it in case I
  • 00:23:22
    don't have it installed here but it
  • 00:23:24
    would find it and then it'll be the same
  • 00:23:25
    difference as we've done with HR you
  • 00:23:27
    click OK and it would just add it again
  • 00:23:30
    I haven't created this group policy
  • 00:23:32
    object but it would come up just like
  • 00:23:33
    this HR one and then what would happen
  • 00:23:36
    is the computer would get Chrome
  • 00:23:39
    installed on this computer Chrome Zoom
  • 00:23:42
    any software that you can think of right
  • 00:23:44
    all of this can be set up so that's the
  • 00:23:47
    whole point of member off okay and then
  • 00:23:50
    of course if you want to make sure that
  • 00:23:52
    you click apply if you want this group
  • 00:23:55
    policy object whether it's secured
  • 00:23:57
    security group or just the regular group
  • 00:24:00
    that installs programs make sure you
  • 00:24:02
    click apply and then okay okay I'm just
  • 00:24:04
    going to cancel out of this
  • 00:24:06
    all right we're going to remove this one
  • 00:24:08
    and I'm going to show you how uh what
  • 00:24:11
    happens actually when I leave the domain
  • 00:24:14
    on the domain compute on the computer
  • 00:24:16
    that has changed during the domain so
  • 00:24:18
    this is the same computer this is the
  • 00:24:19
    Windows 10 machine I'm just going to
  • 00:24:22
    take it out of it and I'm just gonna
  • 00:24:24
    Type in work group this is what comes up
  • 00:24:26
    default on the
  • 00:24:29
    computer itself so I'm just going to
  • 00:24:31
    click ok I'm going to click through all
  • 00:24:32
    of this I'm going to reboot and now I
  • 00:24:34
    know you'll suddenly see that the actor
  • 00:24:36
    directory can tell that I have removed
  • 00:24:39
    the computer and now I have to use my
  • 00:24:42
    credentials again for the domain so I
  • 00:24:43
    can remove it
  • 00:24:45
    okay I'm going to remove it and then
  • 00:24:47
    once we reboot we can see that the
  • 00:24:49
    computer is no longer part of the
  • 00:24:51
    domains all right so click reboot
  • 00:24:55
    so I'm going to watch we're going to
  • 00:24:56
    watch this in real time you'll see this
  • 00:24:58
    icon change here
  • 00:24:59
    all right so it's rebooting and it
  • 00:25:01
    should come up here I may have to
  • 00:25:03
    refresh
  • 00:25:04
    so yeah let me just go ahead and refresh
  • 00:25:06
    here so I'm going to do where is my
  • 00:25:09
    refresh here
  • 00:25:10
    it is action refresh you see now this
  • 00:25:13
    tells us that the computer is down that
  • 00:25:16
    means it's the main itself knew that
  • 00:25:19
    this was part of the the menu that this
  • 00:25:22
    computer was part of the main that it
  • 00:25:23
    was at some point joined to The Domain
  • 00:25:25
    and now it's basically telling you it's
  • 00:25:28
    down it could be offline right as far as
  • 00:25:32
    actor directory is concerned it's
  • 00:25:34
    thinking that this computer is either
  • 00:25:36
    offline or no longer part of the domain
  • 00:25:38
    right and this is why you get the arrow
  • 00:25:40
    so this is the good indicator for you to
  • 00:25:42
    see now let's see if you were to do a
  • 00:25:45
    search for it do you actually get that
  • 00:25:47
    icon as well well let's find out right
  • 00:25:49
    so we're gonna do work
  • 00:25:52
    that's the name of the computer and see
  • 00:25:54
    this is very important to know when you
  • 00:25:56
    do a search for it when you just do a
  • 00:25:58
    search for it it doesn't tell you that
  • 00:26:00
    there's something wrong with the
  • 00:26:01
    computer like this unless you right
  • 00:26:04
    click and then you try to manage and
  • 00:26:06
    then you suddenly realize ah you know
  • 00:26:08
    there's it's it's broken right
  • 00:26:10
    something's wrong and so for those
  • 00:26:13
    reasons you want to actually navigate to
  • 00:26:15
    the folder where you know that where the
  • 00:26:17
    computer will be
  • 00:26:19
    and so you can see that there's
  • 00:26:21
    something wrong with it now there are
  • 00:26:24
    tools like Microsoft endpoint that allow
  • 00:26:27
    you to view the same type of information
  • 00:26:28
    so you can install Microsoft endpoint
  • 00:26:31
    manager on your computer and you can
  • 00:26:34
    search computers and to view this type
  • 00:26:36
    of information as well again that's a
  • 00:26:39
    future video you gotta let me know in
  • 00:26:41
    the comments whether you're interested
  • 00:26:42
    in that okay so our Windows 10 computer
  • 00:26:45
    has rebooted once more
  • 00:26:49
    so I'm going to log back into it and
  • 00:26:50
    then we're going to join it with a
  • 00:26:52
    completely different name and this time
  • 00:26:56
    we are not we are not going to go in
  • 00:26:59
    here and ahead of time create a new
  • 00:27:02
    computer we are not going to do this
  • 00:27:05
    this is because I want to show you that
  • 00:27:07
    you can actually add computers to a
  • 00:27:09
    domain
  • 00:27:10
    as long as there is a communication with
  • 00:27:12
    the domain and you have administrator
  • 00:27:14
    privileges to do so for the domain you
  • 00:27:17
    can join a brand new computer without
  • 00:27:19
    having to go through this part of it
  • 00:27:22
    here
  • 00:27:23
    okay so we're now going to do everything
  • 00:27:25
    when it comes to creating and adding new
  • 00:27:28
    computer name and adding to the domain
  • 00:27:31
    here through this manual way of doing it
  • 00:27:34
    all right so I'm going to go back to our
  • 00:27:36
    advanced settings here Advanced system
  • 00:27:39
    settings and as you can see here
  • 00:27:41
    computer name is still work001 however
  • 00:27:45
    we're not part of the domain anymore so
  • 00:27:47
    I'm going to click change so this is
  • 00:27:49
    what we're going to do we're going to
  • 00:27:51
    change it to work group uh work zero
  • 00:27:56
    zero zero two
  • 00:27:57
    all right we're going to say zero zero
  • 00:28:00
    zero two okay and then we're going to
  • 00:28:01
    type in new domain.com so we're gonna
  • 00:28:06
    add make it a member of the main again
  • 00:28:08
    so this is the name of the domain
  • 00:28:10
    newdomain.com and now I'm telling the
  • 00:28:13
    domain I want to join this computer to
  • 00:28:16
    our domain but I want to use this other
  • 00:28:18
    name which is zero zero two again we're
  • 00:28:20
    going to go back to the server itself
  • 00:28:22
    it's not in here it's not in here zero
  • 00:28:25
    zero two is not in here okay I'm gonna
  • 00:28:27
    click ok
  • 00:28:30
    and it's going to now ask me for
  • 00:28:32
    administrator privileges maybe
  • 00:28:34
    straighter
  • 00:28:40
    all right click ok
  • 00:28:44
    here we go welcome to newdomain.com now
  • 00:28:47
    before okay so I'm going to click OK and
  • 00:28:49
    I'm going to switch to the to the uh
  • 00:28:51
    thing okay well all right fine let's do
  • 00:28:54
    a reboot here I'm gonna switch to this
  • 00:28:56
    here and let's do action refresh
  • 00:29:00
    and here it is here is our work zero
  • 00:29:04
    zero zero two you see so you can do a
  • 00:29:07
    couple of different ways depends on how
  • 00:29:10
    things are done with your company I just
  • 00:29:13
    want you to know that it works both ways
  • 00:29:15
    and you can do it both ways you know
  • 00:29:17
    there are some specific things very
  • 00:29:19
    Niche things in which case you'd want to
  • 00:29:22
    do uh you want to create uh host names
  • 00:29:25
    ahead of time but in some cases you
  • 00:29:27
    don't necessarily have to anyways
  • 00:29:31
    I'm not going to make that too
  • 00:29:33
    complicated I just want to show you that
  • 00:29:34
    it's possible to do it
  • 00:29:36
    okay
  • 00:29:37
    so that's that part of it okay all right
  • 00:29:42
    now so you've noticed that for all of
  • 00:29:44
    these things that I've been doing I've
  • 00:29:46
    been just using a regular administrator
  • 00:29:48
    login which comes with domain so if I
  • 00:29:52
    click on users here's the account that I
  • 00:29:54
    was using for to add this computer to
  • 00:29:57
    The Domain which is not a good idea at
  • 00:30:00
    all which is not a good idea for those
  • 00:30:02
    reasons we're going to have to create a
  • 00:30:05
    new user that will give me administrator
  • 00:30:08
    privileges all right so let's go ahead
  • 00:30:10
    and do this we're just going to right
  • 00:30:12
    click users and just to keep it simple
  • 00:30:15
    so this is users folder OU if you will
  • 00:30:17
    and this is just a default one and we're
  • 00:30:20
    going to organize this a little bit here
  • 00:30:22
    but that's okay let's so right click
  • 00:30:24
    users just just a placeholder for now
  • 00:30:27
    and we're going to select new and of
  • 00:30:30
    course you've guessed that we're going
  • 00:30:31
    to create a new user and I'm going to
  • 00:30:33
    create a new user called uh call boo man
  • 00:30:37
    why not because that's my Alias here on
  • 00:30:41
    YouTube and I'm gonna just use Cobo man
  • 00:30:44
    as the login ID
  • 00:30:46
    and I'm going to click next and I'm
  • 00:30:48
    going to set my new password
  • 00:30:50
    this is going to be a temporary password
  • 00:30:55
    okay it says here user must change the
  • 00:30:57
    password next logon we're gonna see that
  • 00:31:00
    because we're going to log in with this
  • 00:31:01
    to the Windows 10 machine I'm going to
  • 00:31:03
    click next and I'm going to click finish
  • 00:31:05
    now I want this account to have more
  • 00:31:09
    than just regular standard login and for
  • 00:31:13
    those Reasons I'm going to give it
  • 00:31:15
    administrator privileges so there are a
  • 00:31:18
    couple of ways of doing this now we're
  • 00:31:22
    going to do this the way you would
  • 00:31:24
    normally do it in a business environment
  • 00:31:26
    that you already started working at so I
  • 00:31:28
    don't want you to think about it how too
  • 00:31:30
    much how it works at least not for now
  • 00:31:32
    although I will explain it briefly now I
  • 00:31:36
    want to kind of organize this because I
  • 00:31:38
    don't want this administrator account to
  • 00:31:39
    be just in this default here I wanted to
  • 00:31:42
    move it to a different
  • 00:31:44
    OU or different folder if you will and I
  • 00:31:46
    just so happen to have a folder for this
  • 00:31:48
    under the main controller and there's
  • 00:31:50
    one here called tech support so I'm
  • 00:31:52
    going to move that user to tech support
  • 00:31:54
    and I'm just going to find Kobo man or
  • 00:31:57
    we can just search for him and this and
  • 00:31:59
    that but here he is on the bottom so I'm
  • 00:32:01
    just going to right click and then we're
  • 00:32:03
    going to select to move and then I'm
  • 00:32:05
    going to select the main controller here
  • 00:32:07
    I'm going to add him to tech support
  • 00:32:09
    OU
  • 00:32:11
    so this is just way to organize it
  • 00:32:14
    however notice here in tech support
  • 00:32:16
    group there's also a security group
  • 00:32:18
    right security group that gives that
  • 00:32:21
    gives us right that will give us
  • 00:32:24
    administrator privileges so the way this
  • 00:32:27
    is designed is actually if I right click
  • 00:32:29
    Cobo man and then I go to properties and
  • 00:32:33
    then I go to member off so now right now
  • 00:32:36
    this is different from controlling the
  • 00:32:38
    computer the main thing here you can do
  • 00:32:41
    is related to security right the
  • 00:32:45
    security so we're going to click add I'm
  • 00:32:47
    going to type in Tech Support here just
  • 00:32:50
    to search for it
  • 00:32:52
    and this Security Group will grant me
  • 00:32:54
    administrator access admin privileges so
  • 00:32:58
    if I click OK apply suddenly
  • 00:33:01
    Kobo man has this privileges right so
  • 00:33:04
    instead of having to manually doing this
  • 00:33:07
    and that you would just create one
  • 00:33:09
    Security Group and then you just add
  • 00:33:11
    people to that Security Group without
  • 00:33:13
    having to go in and make these manual
  • 00:33:16
    changes so what do I mean by this if I
  • 00:33:20
    go to my Windows 10 computer and now we
  • 00:33:22
    know that I am indeed logged in as
  • 00:33:25
    Cobble man here right now I am logged in
  • 00:33:28
    as kuboman so you would think that now I
  • 00:33:32
    would have administrator privileges but
  • 00:33:35
    that's not yet the case normally what
  • 00:33:39
    you want to do is in order to get
  • 00:33:43
    administrator privileges on the local
  • 00:33:46
    computer you would have to go in and
  • 00:33:50
    edit local users and groups so here it
  • 00:33:53
    is so this is a security policy on the
  • 00:33:57
    local level on the local computer
  • 00:34:01
    so normally without using security
  • 00:34:05
    groups like I've just added cover man to
  • 00:34:08
    it without having to do that you would
  • 00:34:11
    have to go in here
  • 00:34:13
    select groups and select administrator
  • 00:34:16
    group on the local computer at local
  • 00:34:19
    level so you would manually manually
  • 00:34:22
    have to do it you have to double click
  • 00:34:24
    on this and then I would have to go in
  • 00:34:27
    here and add kabuman
  • 00:34:31
    as an administrator to this computer and
  • 00:34:34
    then allow him to be part of this and
  • 00:34:37
    this is not going to work because he
  • 00:34:39
    doesn't have administrator privileges
  • 00:34:41
    yet you see that it says access denied
  • 00:34:45
    because it hasn't replicated the
  • 00:34:49
    security group that I've added coboman
  • 00:34:51
    to which is this here it hasn't
  • 00:34:54
    replicated at local level
  • 00:34:58
    meaning that it hasn't replicated and
  • 00:35:00
    added Cobble man in here automatically
  • 00:35:03
    and I will show you how to do this so
  • 00:35:06
    I'm going to cancel out of this so you
  • 00:35:07
    can see what happens again this is at
  • 00:35:10
    local level that Security Group here
  • 00:35:13
    Security Group here is designed to
  • 00:35:17
    replicate this action here you know you
  • 00:35:20
    go into groups at local level
  • 00:35:22
    administrator and then you add that
  • 00:35:26
    administrator privileges to that so this
  • 00:35:29
    is what we're going to do
  • 00:35:31
    we're going to go back to the server
  • 00:35:33
    here and then we're going to look up
  • 00:35:35
    that computer right we're going to look
  • 00:35:37
    up this computer all right we're going
  • 00:35:39
    to do find we're going to look them up
  • 00:35:42
    we're just going to pretend like we
  • 00:35:43
    don't know where it's at so we're just
  • 00:35:44
    going to type in work
  • 00:35:48
    and we are logged into work too so we're
  • 00:35:50
    going to right click
  • 00:35:52
    manage
  • 00:35:54
    we're going to right click manage and
  • 00:35:57
    now we are remotely managing we're
  • 00:35:59
    bypassing here right now we don't have
  • 00:36:03
    this Windows 10 we don't have ability to
  • 00:36:05
    make changes in here we do not have make
  • 00:36:07
    ability to make changes here right now
  • 00:36:10
    as logged in as Kobo man on this Windows
  • 00:36:12
    10 machine
  • 00:36:13
    but we can make changes
  • 00:36:16
    over the domain over the through this
  • 00:36:19
    server because we are controlling this
  • 00:36:23
    computer because it's part of our domain
  • 00:36:25
    so here is the same thing we're looking
  • 00:36:27
    at over here is that we're remotely
  • 00:36:30
    connected to that computer
  • 00:36:32
    let me just expand this so this is
  • 00:36:34
    cluster crystal clear I apologize and
  • 00:36:37
    I'm sorry for repeating myself but I
  • 00:36:39
    want you to understand this right now we
  • 00:36:41
    are managing work zero zero zero two
  • 00:36:45
    remotely
  • 00:36:47
    and we're going to click on groups and
  • 00:36:50
    then select administrators here
  • 00:36:52
    right so this is the same thing we're
  • 00:36:54
    watching here
  • 00:36:56
    right this is the same thing as we're
  • 00:36:57
    looking at here in Windows 10.
  • 00:37:00
    except
  • 00:37:02
    while we are in the server we have the
  • 00:37:05
    ability to add people into
  • 00:37:07
    administrators group at the local level
  • 00:37:09
    on that computer
  • 00:37:11
    so instead of having to add kabuman in
  • 00:37:14
    here just cobumet we could just add
  • 00:37:16
    cobbleman here and he'd be the only
  • 00:37:18
    administrator that has the ability to
  • 00:37:21
    make changes right we're actually going
  • 00:37:24
    to guess what we're going to add that
  • 00:37:26
    entire group that is called
  • 00:37:30
    tech support that's Security Group tech
  • 00:37:34
    support
  • 00:37:35
    we're going to add it to this
  • 00:37:38
    and I'm going to click apply then we're
  • 00:37:40
    going to click OK and now if we go to
  • 00:37:44
    our Windows 10 machine and we double
  • 00:37:47
    click this we can now see that tech
  • 00:37:49
    support security group is added in here
  • 00:37:53
    and automatically Kobo man is inside of
  • 00:37:57
    that group
  • 00:37:58
    he's already inside of that group
  • 00:38:02
    remember we went in here
  • 00:38:04
    we looked at our tech support OU here's
  • 00:38:09
    our tech support Security Group
  • 00:38:11
    members of that group and we got Bob
  • 00:38:15
    Smith kobleman and Sammy Rowe so Kobo
  • 00:38:18
    man is part of this Security Group so
  • 00:38:21
    all the people that are added in the
  • 00:38:23
    future here
  • 00:38:25
    they are going to have the same access
  • 00:38:27
    so instead of having to add people
  • 00:38:30
    individually to local computers to have
  • 00:38:32
    administrator privileges you just add
  • 00:38:35
    them to tech support
  • 00:38:37
    Security Group
  • 00:38:40
    Security Group and this is going to get
  • 00:38:43
    replicated automatically over the domain
  • 00:38:46
    it needs to be set up like that the only
  • 00:38:49
    reason I left it like this so it doesn't
  • 00:38:50
    replicate automatically is just so I can
  • 00:38:52
    show you and bring the point over so you
  • 00:38:55
    can understand that
  • 00:38:56
    so now under local computer tech support
  • 00:39:01
    Security Group has been added cobleman
  • 00:39:04
    is part of that and this is you know
  • 00:39:06
    under the administrators under
  • 00:39:08
    administrators I'm going to click OK and
  • 00:39:11
    again this changes came from the domain
  • 00:39:13
    from the active directory
  • 00:39:17
    and I'm just going to close this and now
  • 00:39:20
    coboman has administrator privileges so
  • 00:39:23
    if I open up well
  • 00:39:26
    it should work let me just just do a
  • 00:39:29
    sign out and sign in real quick just to
  • 00:39:31
    make sure
  • 00:39:32
    that it does replicate
  • 00:39:42
    so this is one way to actually make sure
  • 00:39:44
    that your domain changes are replicating
  • 00:39:46
    even if it's just as simple as changing
  • 00:39:49
    the password for somebody so I'm going
  • 00:39:51
    to click on this PC well I I'm let's
  • 00:39:54
    just do this groups
  • 00:39:56
    here we go we're going to go back to
  • 00:39:58
    edit local users and groups remember we
  • 00:40:00
    couldn't do this earlier because we
  • 00:40:03
    didn't have administrator access but if
  • 00:40:05
    I really wanted to now I can go back
  • 00:40:08
    into the administrators on the Windows
  • 00:40:10
    10 machine and I can just add myself if
  • 00:40:13
    I wanted to
  • 00:40:14
    here we go Cobo man again I don't have
  • 00:40:17
    to this is redundant I'm already part of
  • 00:40:19
    this but I just want you to show that
  • 00:40:21
    admin part of it already worked so apply
  • 00:40:23
    you see that now there are no errors no
  • 00:40:27
    errors because now I have inherited
  • 00:40:30
    administrator privileges through this
  • 00:40:33
    Security Group tech support that's been
  • 00:40:35
    added here already right so I can go in
  • 00:40:38
    and remove Cobble man or whatever else I
  • 00:40:41
    want make any changes I want at local
  • 00:40:44
    level
  • 00:40:45
    I hope that comes off as easy to
  • 00:40:48
    understand and I hope it's not too
  • 00:40:49
    complicated for anybody to to figure out
  • 00:40:53
    so yeah I'm just gonna leave it at that
  • 00:40:55
    so the point is just to have a group and
  • 00:40:58
    you keep adding people to the group and
  • 00:40:59
    this group is later on automatically
  • 00:41:02
    added or should be automatically added
  • 00:41:05
    to all the computers that are part of
  • 00:41:08
    this domain part of this actor directory
  • 00:41:11
    so again this is something that can be
  • 00:41:13
    set up later on so that these computers
  • 00:41:16
    can just function like they are this is
  • 00:41:19
    just an example of how this works in the
  • 00:41:23
    second part as promised we're going to
  • 00:41:25
    talk about DHCP Dynamic host
  • 00:41:28
    configuration protocol as usual I always
  • 00:41:31
    talk about things in the sense where
  • 00:41:32
    this is how it would look like if you
  • 00:41:34
    were to get hired to work for a company
  • 00:41:36
    so this is a practical knowledge that
  • 00:41:39
    means that you can sit down at the
  • 00:41:41
    server or a computer and start to do
  • 00:41:44
    start to work on on these things it's
  • 00:41:46
    very easy to understand and I'm going to
  • 00:41:48
    make sure that it is easy to understand
  • 00:41:50
    all right let's get into it but before
  • 00:41:52
    we do that please do me a favor and in
  • 00:41:55
    the comment below just say hello hi or
  • 00:41:57
    present or if you can like the video or
  • 00:41:59
    subscribe that would also be great thank
  • 00:42:01
    you so much so let's get into it
  • 00:42:04
    so here's our server Windows Server 2019
  • 00:42:07
    we're going to log into DHCP and make
  • 00:42:10
    sure that we are running under
  • 00:42:11
    administrator so you can do this with
  • 00:42:13
    the tools that we've installed
  • 00:42:15
    previously on our Windows 10 machine as
  • 00:42:17
    well so if you recall if I go to my
  • 00:42:18
    Windows 10 machine here and if I click
  • 00:42:21
    the start menu we can see that I've
  • 00:42:22
    installed admin tools as well and here
  • 00:42:25
    they are windows administrative tools so
  • 00:42:27
    you can access the hcp remotely so DHCP
  • 00:42:30
    server can be accessed remotely from any
  • 00:42:33
    Windows computer so we can do it like
  • 00:42:35
    that or we can simply go directly to the
  • 00:42:37
    server itself and see and access the
  • 00:42:40
    exact same tools so we're just going to
  • 00:42:42
    go ahead and do that it doesn't matter
  • 00:42:44
    we're going to do it from here we're
  • 00:42:45
    going to open up DHCP so we're going to
  • 00:42:48
    just maximize this and we're going to
  • 00:42:49
    expand here where it says server new
  • 00:42:52
    domain this is basically our DHCP server
  • 00:42:55
    and underneath it are what they're
  • 00:42:57
    called Scopes and we got two different
  • 00:42:59
    Scopes which is ipv4 and IP version 6.
  • 00:43:02
    so let me just expand this and explain
  • 00:43:05
    to you what a scope is in a nutshell a
  • 00:43:08
    scope is basically the IP address range
  • 00:43:12
    that you're going to use for your DHCP
  • 00:43:15
    server so in in the nutshell if I was to
  • 00:43:18
    for example right click IP version 4 and
  • 00:43:21
    I select new scope here we can set up a
  • 00:43:24
    new version of IPA range so let me just
  • 00:43:27
    call it new IP range
  • 00:43:33
    okay I'm going to call it new IP range
  • 00:43:35
    and here it is we're going to start we
  • 00:43:37
    have a starting IP address so we can say
  • 00:43:38
    192
  • 00:43:44
    168.1.0 we can start with that and then
  • 00:43:47
    we can end the IP range with for example
  • 00:43:50
    192.168.1
  • 00:43:55
    dot for example 100 so you'd be able to
  • 00:44:00
    assign IP addresses between these two
  • 00:44:02
    ranges between zero and a 100 so between
  • 00:44:05
    1 and 100 actually
  • 00:44:07
    so and then you can just leave it like
  • 00:44:10
    that and create a new scope I'm going to
  • 00:44:12
    cancel out of this because I've already
  • 00:44:13
    created a new scope right so the reason
  • 00:44:16
    it's called new scope is because you
  • 00:44:18
    know when you look through a scope for
  • 00:44:20
    example like a you know looking glass
  • 00:44:22
    right you're looking looking glass
  • 00:44:23
    whatever is inside of that Looking Glass
  • 00:44:26
    like a circle that's what in this case
  • 00:44:28
    scope means so whatever is inside of
  • 00:44:30
    that in this case it's the IP range so
  • 00:44:34
    if we look at the address pools here for
  • 00:44:36
    an example we can see that here is our
  • 00:44:38
    starting IP address and this is our
  • 00:44:41
    ending IP address so this one is from
  • 00:44:43
    one to a hundred it says here address
  • 00:44:46
    range for distribution so these are the
  • 00:44:48
    IP addresses and AKA IP range that's
  • 00:44:53
    available for us for this specific scope
  • 00:44:56
    and you can have multiple versions of
  • 00:44:59
    different Scopes so you can keep
  • 00:45:00
    expanding on this if you this is used to
  • 00:45:03
    organize an organization so let's say
  • 00:45:06
    you have a certain part of your
  • 00:45:08
    Enterprise that wants to be under this
  • 00:45:10
    IP range then you would create a new
  • 00:45:13
    scope for it to keep track of it right
  • 00:45:15
    so it's for tracking purposes and also
  • 00:45:18
    for organizational purposes right and
  • 00:45:20
    you can do the same thing for IPv6 here
  • 00:45:22
    if you wanted to but we're going to
  • 00:45:24
    concentrate with ipv4 it's explained in
  • 00:45:27
    the same way so I'm just going to stick
  • 00:45:28
    with that next thing is address leases
  • 00:45:31
    for example here is what you see at a
  • 00:45:34
    client IP address and it's just called
  • 00:45:36
    new but what this is and usually would
  • 00:45:38
    say is how long a address is leased for
  • 00:45:42
    that computer so what do I mean by that
  • 00:45:44
    each computer that connects to the DHCP
  • 00:45:47
    server
  • 00:45:48
    is going to have a certain duration of
  • 00:45:51
    how long that IP address is leased to
  • 00:45:55
    them meaning this is how long this
  • 00:45:57
    computer can have this IP address before
  • 00:46:00
    it's renewed unless you create
  • 00:46:03
    reservations
  • 00:46:05
    so to clarify here what you're looking
  • 00:46:07
    at here is and reservation lease so this
  • 00:46:12
    is a reservation lease and these will
  • 00:46:14
    appear as so remember this icon remember
  • 00:46:18
    it says reservation never ever delete
  • 00:46:21
    these unless it's part of your job to
  • 00:46:23
    delete it unless you've been
  • 00:46:25
    specifically told to delete the
  • 00:46:26
    reservation never never delete these now
  • 00:46:30
    what I'm talking about ones that are
  • 00:46:32
    regularly dynamically assigned I'm gonna
  • 00:46:34
    have to find an example that I'm gonna
  • 00:46:36
    have it come up right now so you can see
  • 00:46:38
    an example of dynamically assigned
  • 00:46:42
    leases and since these are Dynamic and
  • 00:46:45
    if you happen to come across a computer
  • 00:46:47
    that has multiple dynamically assigned
  • 00:46:50
    IP addresses and there is a problem
  • 00:46:52
    connecting that computer to the network
  • 00:46:54
    you can delete those okay but always
  • 00:46:57
    double check with your co-workers if you
  • 00:46:59
    don't know where you're doing but again
  • 00:47:01
    make sure they're not reservations so if
  • 00:47:04
    they're regularly leased IPS addresses
  • 00:47:06
    you can right click and delete them why
  • 00:47:08
    because they're dynamically assigned and
  • 00:47:10
    the computer will get a new IP address
  • 00:47:12
    so let's get into the reservations here
  • 00:47:15
    we can see that this computer is also
  • 00:47:18
    added to the reservations so what is
  • 00:47:20
    reservations it's kind of of reverse of
  • 00:47:23
    static IP address static IP address is
  • 00:47:26
    an address that you go to a computer and
  • 00:47:29
    you assign it IP address on the local
  • 00:47:31
    level and then you have to go off of
  • 00:47:33
    that static IP address to configure it
  • 00:47:36
    so this is sometimes done on the
  • 00:47:38
    printers and this and that but I don't
  • 00:47:40
    want you necessarily worry about that
  • 00:47:41
    because nowadays reservations are mainly
  • 00:47:44
    used for IP address tracking and
  • 00:47:47
    assignment so yeah and is it where it
  • 00:47:50
    says as the word reservations says you
  • 00:47:53
    are reserving an IP address specific IP
  • 00:47:57
    address for a computer that's going to
  • 00:47:59
    connect to the DHCP server so how is
  • 00:48:02
    this done well it's done based off the
  • 00:48:05
    MAC address address of those computers
  • 00:48:07
    or components it doesn't have to be like
  • 00:48:09
    a computer in the sense like a PC you
  • 00:48:12
    know when people say it's a computer and
  • 00:48:14
    then people assume that it's your
  • 00:48:16
    desktop your laptop type of computer you
  • 00:48:19
    know or this and that no this can be
  • 00:48:21
    anything it can be tablets it can be
  • 00:48:24
    printers it could be you know cameras
  • 00:48:27
    that run over the the network
  • 00:48:30
    connections or any of that these type of
  • 00:48:32
    things so we're going to cut straight on
  • 00:48:34
    that today so let's go ahead and do this
  • 00:48:36
    and the reason we're going to
  • 00:48:37
    concentrate on this because this would
  • 00:48:39
    be the main thing you would be doing
  • 00:48:40
    when it comes to DHCP server itself so
  • 00:48:43
    let's look up some app my Mac addresses
  • 00:48:46
    so if you don't know what the MAC
  • 00:48:47
    address is for people who are new to
  • 00:48:49
    computers Mac address is a physical
  • 00:48:52
    address meaning there's a physical
  • 00:48:54
    number for your computer that that is
  • 00:48:59
    unique in the entire world that
  • 00:49:01
    identifies your computer for the sake of
  • 00:49:04
    connecting
  • 00:49:05
    all right so let's just do ipconfig
  • 00:49:08
    forward slash all here
  • 00:49:11
    so I can show you an example of that
  • 00:49:13
    this is the MAC address it's also known
  • 00:49:15
    as a physical address and this computer
  • 00:49:18
    on this computer the network adapter
  • 00:49:20
    here where it says Intel R Pro 1000
  • 00:49:23
    desktop adapter here is its Mac address
  • 00:49:28
    so what we're going to do is we're going
  • 00:49:31
    to identify any other computers
  • 00:49:35
    components or anything that has a Mac
  • 00:49:37
    and address so we're going to tell the
  • 00:49:39
    DHCP server to assign it a specific IP
  • 00:49:43
    address so in this example if I was to
  • 00:49:45
    add this to the DHCP server as soon as
  • 00:49:49
    this computer this computer would
  • 00:49:51
    connect
  • 00:49:52
    and the DHCP server would see this Mac
  • 00:49:55
    address it says oh yeah so this is the
  • 00:49:58
    computer with that Mac address well okay
  • 00:50:00
    I'm going to assign it a specific IP
  • 00:50:04
    address so it can have that specific IP
  • 00:50:07
    address we're going to reserve an IP
  • 00:50:10
    address based off the physical address
  • 00:50:13
    of that computer
  • 00:50:16
    so this is simply done by you know go to
  • 00:50:18
    the reservations right click new
  • 00:50:21
    reservation and then we can name it and
  • 00:50:24
    then we can add the IP address so again
  • 00:50:26
    as I said we're just going to look up
  • 00:50:28
    some random Mac addresses for random
  • 00:50:30
    things so what's something that would be
  • 00:50:33
    reserved well you know let's say a
  • 00:50:37
    printer we're going to just type in
  • 00:50:38
    printer Mac address
  • 00:50:42
    and hopefully we get an example of a MAC
  • 00:50:44
    address here for a printer so we can
  • 00:50:46
    just keep going off of that so I'm just
  • 00:50:48
    going to look at the images here just so
  • 00:50:49
    we can find a MAC address here's a MAC
  • 00:50:52
    address for our printer and this is
  • 00:50:54
    based of a printer status
  • 00:50:57
    hopefully comes up so I can see it
  • 00:51:01
    Macintosh we're going to zoom in we're
  • 00:51:03
    going to zoom in and definitely see what
  • 00:51:04
    this is so here is what typically would
  • 00:51:08
    be a configuration setting for a printer
  • 00:51:11
    so like a printer sheet that you would
  • 00:51:15
    print out you go to a computer and you
  • 00:51:17
    say
  • 00:51:18
    print out the configuration so I can see
  • 00:51:20
    what the MAC address here is it's a
  • 00:51:22
    little bit blurry but that's okay we can
  • 00:51:23
    figure out this one here it says 2c9e
  • 00:51:28
    fc1e7d84 so we're going to use that
  • 00:51:30
    we're going to pretend like we're adding
  • 00:51:32
    this printer as well so we're going to
  • 00:51:33
    go back to our
  • 00:51:36
    DHCP manager I'm just let me do some
  • 00:51:39
    organization here so we can see it a
  • 00:51:41
    little bit easier
  • 00:51:43
    all right so again we're going to right
  • 00:51:45
    click reservations new reservation and
  • 00:51:48
    we're going to call it
  • 00:51:51
    printer we're going to keep it simple
  • 00:51:52
    we're going to call it printer and again
  • 00:51:54
    remember in this scope we have a range
  • 00:51:56
    between 1 and 200. so we have to make
  • 00:52:00
    sure we pick an IP address that's not
  • 00:52:02
    being used we can see there are current
  • 00:52:04
    reservation for the example one that
  • 00:52:06
    I've entered in here and look it says
  • 00:52:08
    it's it's 15. so we cannot use that one
  • 00:52:11
    we cannot use
  • 00:52:12
    100.15 we're going to have to use some
  • 00:52:15
    other IP address so we're going to just
  • 00:52:18
    say
  • 00:52:19
    Dot 20 right just to you know it could
  • 00:52:23
    be anything it could be 16 or whatever
  • 00:52:25
    it is that you want right so and then
  • 00:52:28
    here it is where we type in our Mac
  • 00:52:30
    address so we're going to type it in and
  • 00:52:32
    we're going to use an example one that
  • 00:52:33
    we have here which I'm going to keep it
  • 00:52:35
    next to it
  • 00:52:36
    so it is 2C 9 e f c one
  • 00:52:40
    e784 so we're going to type it we're
  • 00:52:43
    going to type it in we're just going to
  • 00:52:44
    type it in as it as it is no spaces no
  • 00:52:47
    dashes none of that stuff we're just
  • 00:52:49
    going to straight through type it in so
  • 00:52:51
    it's 2C 9e fc1e
  • 00:52:56
    seven d eight four okay and then we're
  • 00:53:00
    going to type in a description we're
  • 00:53:02
    going to say printer IP address
  • 00:53:07
    okay and I'm just going to click
  • 00:53:11
    add we don't have to change anything
  • 00:53:12
    here we're just going to where it says
  • 00:53:14
    supported types just leave it at both
  • 00:53:15
    and we're going to click add okay and
  • 00:53:18
    now it's added here so we can close this
  • 00:53:20
    so let me just go back to maximize the
  • 00:53:23
    window so we can see what happened here
  • 00:53:24
    and here is our printer that we've added
  • 00:53:28
    under reservation so if you just select
  • 00:53:30
    reservations folder you can see all the
  • 00:53:31
    things that are under that are reserved
  • 00:53:33
    and here it is here is our printer and
  • 00:53:36
    it has a reserved an IP address of
  • 00:53:41
    192.168.100.20 so as soon as this
  • 00:53:44
    printer connects to our Network it's
  • 00:53:47
    going to get that IP address it's going
  • 00:53:51
    to get that IP address and it's going to
  • 00:53:54
    keep getting that IP address so we know
  • 00:53:57
    that DHCP stands for a dynamic host
  • 00:54:00
    configuration protocol and normally when
  • 00:54:04
    computers are connected to a DHCP
  • 00:54:07
    DHCP server then they would get
  • 00:54:10
    dynamically just randomly assigned IP
  • 00:54:14
    addresses we don't want that we don't
  • 00:54:16
    want that for printers obviously so
  • 00:54:19
    we're going to tell it as soon as that
  • 00:54:22
    printer with that Mac address connects
  • 00:54:24
    make sure it gets this specific reserved
  • 00:54:28
    IP address and you know we can go to
  • 00:54:31
    properties and we can see the same thing
  • 00:54:33
    here again make sure you don't use any
  • 00:54:36
    spaces no dashes none of that stuff and
  • 00:54:39
    this is how this is done very simple
  • 00:54:42
    right
  • 00:54:43
    all right so if we go to address leases
  • 00:54:45
    you can see that our printer also shows
  • 00:54:47
    up however it's not connected so let's
  • 00:54:50
    do a couple of more let's see what else
  • 00:54:51
    we can do like one of the recent things
  • 00:54:54
    I've done is a camera so I'm going to
  • 00:54:58
    just type in
  • 00:55:01
    I'm going to type in IP
  • 00:55:04
    camera Mac address
  • 00:55:07
    and here's an example of this if you
  • 00:55:09
    want to look at the physical one and
  • 00:55:12
    here it is well this is Mac ID here is
  • 00:55:14
    blurred out which rightfully sell right
  • 00:55:16
    because otherwise you can intercept that
  • 00:55:18
    connection potentially right so here's I
  • 00:55:21
    guess this is a D-Link IP camera and you
  • 00:55:24
    would you can set it up the same way
  • 00:55:26
    here's the Mac ID here but well you know
  • 00:55:28
    it would be here but it's blurred out
  • 00:55:30
    right for the right reasons uh let me
  • 00:55:33
    see if I can find a different one uh
  • 00:55:35
    let's see here
  • 00:55:37
    images
  • 00:55:40
    uh here's one
  • 00:55:43
    can we see this one okay here it is so
  • 00:55:45
    here is a MAC address for this camera
  • 00:55:47
    we're going to use this one too so we're
  • 00:55:49
    going to add an IP camera again we're
  • 00:55:52
    going to right click reservations folder
  • 00:55:54
    here new reservation and uh
  • 00:55:59
    oopsie let me minimize this
  • 00:56:03
    I'm going to do new reservation
  • 00:56:06
    and let me just
  • 00:56:08
    do some zooming action here
  • 00:56:16
    all right
  • 00:56:17
    so we can see better
  • 00:56:20
    it's a good image when zoomed in how
  • 00:56:22
    about that
  • 00:56:23
    okay I'm just trying to orient it so we
  • 00:56:27
    can see the MAC address all right here
  • 00:56:28
    we go so we're going to call it
  • 00:56:31
    IP camera I'm going to call it
  • 00:56:36
    Corridor corridor
  • 00:56:40
    Corridor one sure why not I'm just going
  • 00:56:43
    to do a copy paste action here for the
  • 00:56:46
    description
  • 00:56:49
    and we're going to assign it an IP
  • 00:56:51
    address of
  • 00:56:52
    30.
  • 00:56:53
    okay I'm going to click uh well we're
  • 00:56:56
    gonna say we're going to click add but
  • 00:56:57
    we haven't added the MAC address yet so
  • 00:56:59
    all right so what it what is it here
  • 00:57:02
    twenty five nine a let's type it in
  • 00:57:05
    20 59 a 0 f 5 a f two three
  • 00:57:13
    okay we're going to click add so there
  • 00:57:15
    are there is our IP camera added and so
  • 00:57:20
    it's the same type of deal you know it's
  • 00:57:21
    important to give it the description uh
  • 00:57:24
    you know good name and make sure that
  • 00:57:26
    you keep it in the range so let's say if
  • 00:57:28
    I was to go in and potentially have 10
  • 00:57:32
    more printers
  • 00:57:34
    I can just continue with this range that
  • 00:57:36
    I kind of have it it's not a kind of
  • 00:57:38
    mini range it's not necessarily a new
  • 00:57:40
    Range because the range is between 1 and
  • 00:57:43
    200 as we've looked at before you know
  • 00:57:45
    it says between 1 and 200 but I've
  • 00:57:48
    created kind of my own organizational
  • 00:57:50
    range
  • 00:57:52
    for this printer here
  • 00:57:54
    so for example let's say I was to have
  • 00:57:56
    20 more printers or I'm sorry 10 more
  • 00:57:59
    printer is added to here I can just
  • 00:58:01
    continue with you know 198
  • 00:58:06
    168.100.21 and keep it between 21 and 29
  • 00:58:11
    right so you know let's say I go in here
  • 00:58:13
    and I do new reservation
  • 00:58:16
    and I'm gonna say
  • 00:58:19
    uh
  • 00:58:20
    printer
  • 00:58:22
    number two
  • 00:58:25
    and
  • 00:58:26
    you know we can specify where it's where
  • 00:58:29
    it's at so we can say
  • 00:58:31
    I don't know
  • 00:58:33
    reception right reception
  • 00:58:37
    as in like the front reception where you
  • 00:58:40
    check people in type of deal and so
  • 00:58:42
    since I've added uh 100.20 I'm just
  • 00:58:46
    going to make this dot 21. so I'm
  • 00:58:48
    creating my own organizational thing in
  • 00:58:51
    here right so I'm going to need a MAC
  • 00:58:53
    address to add this uh let's see here
  • 00:58:57
    so let me find another printer IP
  • 00:59:00
    address here so we can use
  • 00:59:03
    printer IP address
  • 00:59:07
    a printer Mac address I apologize
  • 00:59:09
    printer Mac address
  • 00:59:15
    here's a hardware address for this jet
  • 00:59:17
    printer so we're going to use that one
  • 00:59:20
    for in our example
  • 00:59:23
    okay okay so this one is zero zero three
  • 00:59:28
    C
  • 00:59:29
    I'm gonna have to do some
  • 00:59:31
    and we're gonna have to close this out
  • 00:59:33
    and mix minimize it
  • 00:59:36
    new reservation
  • 00:59:38
    here we go paste
  • 00:59:42
    so again it's going to be 21 and here is
  • 00:59:45
    our Mac address for our second printer
  • 00:59:49
    which is zero zero three zero
  • 00:59:54
    c131739 f
  • 00:59:56
    so we're going to add that cool okay so
  • 00:59:59
    there we go we've added a second printer
  • 01:00:01
    to it and we're keeping it in the IP
  • 01:00:03
    range so that way it's easier to you
  • 01:00:05
    know look it's a little bit more
  • 01:00:07
    organized right so there you go this is
  • 01:00:09
    how you would add reservations and
  • 01:00:12
    create reservations for computers that
  • 01:00:15
    are going to connect to your DHCP server
  • 01:00:18
    this is how it's done it's very simple
  • 01:00:20
    we're going to talk about DNS today and
  • 01:00:23
    how it works in a business type of
  • 01:00:26
    environment with computers and servers
  • 01:00:29
    and all kinds of things related to the
  • 01:00:31
    DNS now this also expands into the
  • 01:00:34
    internet as well in case you didn't know
  • 01:00:36
    all right before we begin please do me a
  • 01:00:39
    favor in the comment below say hi hello
  • 01:00:41
    or present sort of like in the classroom
  • 01:00:43
    just to uh for me to get a good idea of
  • 01:00:46
    how many people are interested in this
  • 01:00:48
    type of content
  • 01:00:50
    now
  • 01:00:51
    there will be a help desk video too we
  • 01:00:54
    have almost 50 tickets waiting for us
  • 01:00:56
    and if you're also interested in that
  • 01:00:58
    please leave a comment so that way I can
  • 01:01:01
    try to release that as soon as possible
  • 01:01:03
    right now I'm recording this one because
  • 01:01:06
    it's promised it's in order for what
  • 01:01:09
    we've been doing for the past two weeks
  • 01:01:11
    all right so in order for me to explain
  • 01:01:14
    this properly I have to start from the
  • 01:01:17
    very top of what's the most familiar
  • 01:01:19
    thing so let me pull up google.com this
  • 01:01:22
    is on just the Windows 10 machine I'm
  • 01:01:25
    just going to type in
  • 01:01:28
    google.com I now may get an error here
  • 01:01:30
    well maybe not because the system time
  • 01:01:33
    here is off anyways google.com so
  • 01:01:36
    instead of remembering what the IP
  • 01:01:38
    address is for google.com I can just
  • 01:01:42
    type in google.com and when it comes to
  • 01:01:45
    the internet and the networking this is
  • 01:01:47
    what DNS is used for DNS
  • 01:01:51
    lets you just remember google.com
  • 01:01:54
    instead of having to remember the IP
  • 01:01:56
    address of Google server so if I go to
  • 01:01:59
    CMD right command line and we ping
  • 01:02:02
    google.com
  • 01:02:04
    so just to see ping Google
  • 01:02:09
    .com we get an IP address for google.com
  • 01:02:13
    this is where it's located well this can
  • 01:02:16
    also change randomly depending on where
  • 01:02:19
    the server is it doesn't matter but it
  • 01:02:21
    again it doesn't matter because we don't
  • 01:02:24
    have to remember or find out what the IP
  • 01:02:27
    address is for google.com so if I take
  • 01:02:30
    this Ctrl C right I'm going to copy it
  • 01:02:34
    okay it's it's a virtual machine so it's
  • 01:02:36
    not easily let me copy it from CMD
  • 01:02:39
    that's okay we're going to type it in up
  • 01:02:40
    here
  • 01:02:41
    uh so instead of having to type in the
  • 01:02:44
    IP address to reach Google's website we
  • 01:02:47
    can just type in google.com right so
  • 01:02:49
    just to show you here let's see what was
  • 01:02:51
    the IP address again 142.250
  • 01:02:55
    142
  • 01:02:57
    come on 142.50.250.68.142.
  • 01:03:07
    68.142.
  • 01:03:11
    so
  • 01:03:13
    we can just type in HTTPS for hyper text
  • 01:03:17
    transfer protocol because it's a website
  • 01:03:19
    and then we're going to hit enter and
  • 01:03:21
    here it is it takes us to google.com
  • 01:03:23
    it's just it doesn't like it because
  • 01:03:26
    this is what we're doing we're not using
  • 01:03:29
    the the DNS name for it but see it gets
  • 01:03:32
    you to the google.com so we don't have
  • 01:03:34
    to worry about that we can just remember
  • 01:03:36
    what the google.com and the DNS handles
  • 01:03:40
    that for us we don't have to worry about
  • 01:03:42
    the IP addresses
  • 01:03:44
    all right so how does my computer know
  • 01:03:49
    what where the DNS server is for
  • 01:03:53
    google.com so another entity or another
  • 01:03:57
    server somewhere has to provide this
  • 01:04:00
    information to me where google.com is
  • 01:04:04
    and of course there is so if I do
  • 01:04:07
    ipconfig forward slash all on my
  • 01:04:10
    computer we can see a search of DNS
  • 01:04:14
    suffixes in this case we've got
  • 01:04:16
    newdomain.com so this is for our server
  • 01:04:20
    that we've created which we will tie
  • 01:04:23
    everything into and how DNS relates to
  • 01:04:26
    that
  • 01:04:27
    but in this case we have ATT
  • 01:04:31
    local.net so this is a DNS server that
  • 01:04:34
    provided me information
  • 01:04:37
    forwarding information of google.com
  • 01:04:40
    right so the ATT
  • 01:04:43
    local.net is aware constantly and it's
  • 01:04:47
    refreshed where google.com is when it
  • 01:04:50
    comes to its IP address so that my
  • 01:04:53
    computer doesn't have to remember it or
  • 01:04:56
    I don't have to remember it I can just
  • 01:04:58
    type in google.com so this handling of
  • 01:05:01
    google.com forwarding to that Correct
  • 01:05:04
    server is done by ATT
  • 01:05:08
    local.local.net and we can this can be
  • 01:05:11
    also changed you can change your DNS
  • 01:05:13
    server in your network
  • 01:05:15
    adapter settings you can change that too
  • 01:05:18
    for example let's see what Google DNS
  • 01:05:22
    servers are right and it's going to tell
  • 01:05:24
    you right now if I change this for IP
  • 01:05:27
    version 4 and forward it to this custom
  • 01:05:30
    DNS it will forward it to death and you
  • 01:05:34
    can do this this is you can you would
  • 01:05:36
    only do this if you're having problems
  • 01:05:38
    with DNS and you can't figure it out but
  • 01:05:41
    if you go to your adapter settings for
  • 01:05:43
    your network adapter change adapter
  • 01:05:46
    options here double click on your
  • 01:05:48
    ethernet the device or it could be just
  • 01:05:53
    a real Wi-Fi device and when if you go
  • 01:05:55
    to properties here and then go to for
  • 01:05:58
    example Internet Protocol version 4 TCP
  • 01:06:03
    IP over
  • 01:06:05
    IP you can specifically set up the DNS
  • 01:06:09
    server location you can see that I've
  • 01:06:11
    done this for the server to make my
  • 01:06:13
    server work on the virtual machine but
  • 01:06:16
    in here you can specify whatever the
  • 01:06:18
    Google is and in this case it would be
  • 01:06:21
    888 for example like this one so if I go
  • 01:06:24
    to copy here well I can just remember
  • 01:06:26
    what it is right
  • 01:06:27
    so I can just type in preferred DNS or
  • 01:06:32
    alternative DNS and just change this to
  • 01:06:34
    all eights right
  • 01:06:37
    so if I go through here and just delete
  • 01:06:39
    all of this and set up all Eights
  • 01:06:45
    all eights here we go
  • 01:06:48
    I'm trying to tab over but it keeps
  • 01:06:50
    going down so if I set this up to all
  • 01:06:52
    eights and change the for example
  • 01:06:54
    alternative to eight eight four four
  • 01:06:58
    so just like this get out of here window
  • 01:07:03
    so the other one was eight and then come
  • 01:07:07
    on I was trying to tab over this thing
  • 01:07:09
    is finicky
  • 01:07:10
    so I have to click it in each box
  • 01:07:13
    anyways so if I specify use this as
  • 01:07:16
    preferred DNS and the alternative DNS
  • 01:07:18
    server this is basically telling my
  • 01:07:21
    computer use these servers for Internet
  • 01:07:24
    only
  • 01:07:26
    to help me get routed to the other
  • 01:07:29
    website so whether it's google.com
  • 01:07:31
    yahoo.com youtube.com these DNS servers
  • 01:07:35
    that are hosted by Google will route me
  • 01:07:39
    send me to those appropriate web
  • 01:07:42
    addresses so that way I don't have to
  • 01:07:45
    remember or or find out what the IP
  • 01:07:47
    address for those the same type of
  • 01:07:51
    system happens for local servers for
  • 01:07:55
    your company that you're working for so
  • 01:07:57
    you have to set this up computer names
  • 01:07:59
    that you create for your local network
  • 01:08:02
    the same thing has to be done and in my
  • 01:08:05
    case I have a DNS server that's set up
  • 01:08:07
    to do that and you've already seen where
  • 01:08:10
    the location of it is and let's let's
  • 01:08:13
    pull it up again CMD
  • 01:08:16
    ipconfig forward slash all
  • 01:08:20
    and that is hosted and done by
  • 01:08:24
    newdomain.com so we're going to switch
  • 01:08:26
    over to the server to see what this is
  • 01:08:28
    here we go so we pull up our
  • 01:08:31
    administrative tools find DNS and here
  • 01:08:35
    is our DNS and what does it do well it's
  • 01:08:39
    doing the exactly what I just told you
  • 01:08:41
    about so let me explain this so it's
  • 01:08:43
    easy to understand what I'm going to
  • 01:08:45
    open up active directory here actor
  • 01:08:48
    directory users and computers if you
  • 01:08:51
    watched my previous videos and if you
  • 01:08:53
    haven't I highly suggest that you do
  • 01:08:55
    especially the one on ad we can see that
  • 01:08:58
    we have some computers that we have
  • 01:09:01
    created and added to our domain first
  • 01:09:04
    one let's concentrate just on this one
  • 01:09:06
    here where it says work dash zero zero
  • 01:09:09
    zero two this is our computer that was
  • 01:09:13
    added to our domain and you can see its
  • 01:09:15
    extension so it's part of our new domain
  • 01:09:17
    meaning it's part of our local cold
  • 01:09:20
    domain a local network well we need to
  • 01:09:24
    have a way to reach work dash dash zero
  • 01:09:28
    two just like this on our Network so if
  • 01:09:31
    I just open up Explorer and do a
  • 01:09:34
    backslash backslash meaning we're going
  • 01:09:36
    to use a network path to reach it and
  • 01:09:38
    type in work
  • 01:09:39
    Dash zero zero zero two and if we want
  • 01:09:45
    to see dollar sign into it so C dollar
  • 01:09:48
    sign meaning we're trying to reach a
  • 01:09:51
    shared network location in this case
  • 01:09:54
    we're going to try to see dollar sign
  • 01:09:56
    into this computer as if it was like a
  • 01:09:59
    back door into this computer so we can
  • 01:10:01
    look at the file system so if we hit
  • 01:10:03
    that we can have direct access to it
  • 01:10:06
    this wouldn't be possible this wouldn't
  • 01:10:08
    be possible if the DNS server wasn't set
  • 01:10:13
    up correctly so we don't have to figure
  • 01:10:15
    out what the IP address is here
  • 01:10:18
    otherwise we would have to put in the IP
  • 01:10:20
    address here instead of just typing in
  • 01:10:24
    the name of the computer so let's go
  • 01:10:26
    back to our computer and here it is we
  • 01:10:28
    have we still have the command line
  • 01:10:30
    popped up for work zero zero two and
  • 01:10:33
    here it is work zero zero two this is
  • 01:10:36
    the computer name that we just used and
  • 01:10:39
    we didn't have to figure out what the IP
  • 01:10:41
    address is for that we were just able to
  • 01:10:42
    type it in and we were able to reach it
  • 01:10:44
    on our local network if DNS didn't work
  • 01:10:47
    this is what we would have to do we
  • 01:10:50
    would have to type in the IP address of
  • 01:10:52
    this computer so we can reach it now
  • 01:10:55
    imagine if there are a thousands of
  • 01:10:56
    computers in your company do you really
  • 01:10:59
    want to go through and trying to figure
  • 01:11:01
    out which one it is no this is what the
  • 01:11:03
    NS is for so just to show you here we're
  • 01:11:06
    going to type in 192.
  • 01:11:09
    dot 168 that was at zero that
  • 01:11:15
    100.5 dot 100
  • 01:11:18
    .5 so this is if DNS is broken on your
  • 01:11:23
    on your network on your work Network
  • 01:11:25
    this is how would you would reach these
  • 01:11:27
    computers so you hit enter and it gives
  • 01:11:28
    you the same uh result except this time
  • 01:11:31
    you use the IP address instead of the
  • 01:11:35
    computer name
  • 01:11:36
    okay so the same thing is if you're
  • 01:11:40
    trying to RDP meaning using remote
  • 01:11:42
    desktop protocol to reach these
  • 01:11:44
    computers
  • 01:11:45
    I can just type in
  • 01:11:48
    work
  • 01:11:50
    Dash zero zero zero two
  • 01:11:53
    click connect
  • 01:11:55
    and as long as a remote connection is
  • 01:11:59
    enabled on that computer and it's
  • 01:12:00
    allowed to connect it will pop up
  • 01:12:02
    otherwise I would have to use the IP
  • 01:12:06
    address
  • 01:12:09
    like this and it would let me reach the
  • 01:12:11
    same computer but I think our remote
  • 01:12:13
    desktop is disabled so that's okay
  • 01:12:17
    so how is this working inside of a d
  • 01:12:21
    well the ad part of it basically just
  • 01:12:25
    handles well which you know computer
  • 01:12:27
    name do we want to use and when it comes
  • 01:12:30
    to forwarding to the correct IP address
  • 01:12:33
    that we've just talked about this is
  • 01:12:35
    done by DNS and it's done in forwarding
  • 01:12:38
    lookup zones right so here it is we
  • 01:12:42
    expand this folder and we select new
  • 01:12:44
    domain we can see that there is an a
  • 01:12:47
    record for our work zero zero zero two
  • 01:12:51
    computer
  • 01:12:53
    and we're going to talk about this but
  • 01:12:56
    we can see that work zero zero zero two
  • 01:12:59
    right here just look at it it's
  • 01:13:03
    forwarded to this IP address and it says
  • 01:13:08
    192.168.100.5 which we've just used
  • 01:13:11
    right so if I go to properties of it you
  • 01:13:15
    can see that's exactly what's going on
  • 01:13:17
    here and this is called an a record
  • 01:13:20
    right so what is an a record it's just
  • 01:13:24
    basically a way of basically forwarding
  • 01:13:28
    this it's a simple way of of handling
  • 01:13:30
    the DNS data forwarding that's what that
  • 01:13:34
    is and the same thing is done for
  • 01:13:36
    websites like google.com yahoo.com even
  • 01:13:41
    if you like create your own website
  • 01:13:43
    let's say you're creating your own
  • 01:13:45
    website and you have a web server you
  • 01:13:47
    have to go to your DNS provider DNS
  • 01:13:51
    provider so let's say you have
  • 01:13:53
    I don't know hosting somewhere else for
  • 01:13:56
    your domain name so let's say you've
  • 01:13:58
    created a new website called
  • 01:14:00
    mynewebsite.com well you have to uh you
  • 01:14:04
    have to reserve that name
  • 01:14:06
    from a domain provider you know how you
  • 01:14:08
    have to pay a monthly fee to have that
  • 01:14:10
    name that provider will give you the
  • 01:14:14
    settings where you can add an a record
  • 01:14:17
    to forward to your server's IP address
  • 01:14:22
    right in this case you know this is an
  • 01:14:25
    example of just on on the network but if
  • 01:14:28
    you were if it was a website this is
  • 01:14:29
    what you would do and you can manually
  • 01:14:31
    add them and normally you would be doing
  • 01:14:34
    this in case you're adding for example a
  • 01:14:36
    printer or something like that and you
  • 01:14:39
    want to make sure that there is an a
  • 01:14:40
    record of it then you would have to do
  • 01:14:43
    this manually otherwise this is done
  • 01:14:46
    automatically for computers that are
  • 01:14:48
    joined to the active directory
  • 01:14:52
    now this is automatically done in here
  • 01:14:54
    for computers that are joined to the
  • 01:14:57
    actor directory so if I join a new
  • 01:14:59
    computer create a new host name in here
  • 01:15:01
    and this will automatically be forwarded
  • 01:15:05
    inside of the DNS server for that and
  • 01:15:08
    that's fine and that's fine but if
  • 01:15:10
    you're for example adding a printer let
  • 01:15:12
    me see do I have print server installed
  • 01:15:14
    on here I may not have print server
  • 01:15:16
    installed in here
  • 01:15:18
    uh okay I don't have a print server
  • 01:15:20
    installed it well print printer print
  • 01:15:22
    management here it is
  • 01:15:25
    so if I go to the print server here and
  • 01:15:28
    add a new printer Right add a new
  • 01:15:31
    printer in here I would have to create
  • 01:15:34
    an a record for that so if I go to here
  • 01:15:36
    and add a new network printer in order
  • 01:15:39
    to make it work properly I would have to
  • 01:15:42
    ensure that there is an a record for it
  • 01:15:44
    so let's create a new host uh host a
  • 01:15:49
    record a new a record I should say so
  • 01:15:52
    this would normally be done manually if
  • 01:15:55
    you're for example adding like a new
  • 01:15:56
    printer a new network printer that has
  • 01:15:59
    like a static IP address which is like
  • 01:16:01
    maybe hard coded into the printer itself
  • 01:16:04
    and that's fine so we're going to
  • 01:16:06
    pretend that we're going to do this for
  • 01:16:08
    a printer so we're going to type in
  • 01:16:11
    I don't know we're going to call it new
  • 01:16:13
    network just going to call it network
  • 01:16:14
    printer make sure there are no spaces
  • 01:16:16
    whenever so you can't have like this
  • 01:16:19
    you can't have a space matter of fact
  • 01:16:21
    I'll show you it's not going to work but
  • 01:16:22
    we're going to pretend like this printer
  • 01:16:24
    has a new IP address
  • 01:16:26
    so basically what you would do is you
  • 01:16:29
    would go to that printer it will go to
  • 01:16:31
    that printer and print out a status page
  • 01:16:34
    for that printer to see what
  • 01:16:36
    configurations are for it and that would
  • 01:16:38
    tell you what the IP address is so if
  • 01:16:41
    it's a hard-coded hard-coded IP address
  • 01:16:44
    for that printer and you have no choice
  • 01:16:46
    but to point this
  • 01:16:49
    uh Network
  • 01:16:50
    This Record to that IP address then you
  • 01:16:54
    have to find out what the static IP
  • 01:16:55
    address that's on the printer itself so
  • 01:16:58
    just like 192 that's
  • 01:17:01
    uh
  • 01:17:03
    168.100 I'm going to stay within the
  • 01:17:05
    same IP range that we have and I'm going
  • 01:17:07
    to just say say 25 and leave create
  • 01:17:11
    Associated pointer record PTR record
  • 01:17:14
    basically this is what we're creating
  • 01:17:15
    leave that checked I'm going to click
  • 01:17:17
    add and of course it's not going to work
  • 01:17:19
    because remember we have a space in here
  • 01:17:21
    we can't have a space in here for the
  • 01:17:23
    name we're going to click add and there
  • 01:17:25
    it is the host record for network
  • 01:17:26
    printer has been created
  • 01:17:30
    successfully right so now we can point
  • 01:17:33
    to this network printer we don't have to
  • 01:17:36
    remember that this printer name is
  • 01:17:38
    192.168.100.
  • 01:17:41
    25 all right so what else can we talk
  • 01:17:46
    about so just to kind of reiterate now
  • 01:17:49
    we know what the point of DNS is we
  • 01:17:52
    don't have to remember IP addresses we
  • 01:17:55
    can just use computer names this is why
  • 01:17:58
    we have these a records that are put
  • 01:18:00
    inside of the DNS server that forwards
  • 01:18:03
    these things but we can also look at
  • 01:18:05
    what the reverse lookup is and it's
  • 01:18:06
    right here so what we're dealing here
  • 01:18:08
    with is uh reverse or I'm sorry forward
  • 01:18:12
    lookup zones and by the way before we
  • 01:18:14
    hit the reverse lookup zones if you you
  • 01:18:17
    know click on this new domain and there
  • 01:18:20
    are thousands of Records which chances
  • 01:18:22
    are chances are that it are and you need
  • 01:18:24
    to look for a specific record you can
  • 01:18:27
    right click and go to view and then
  • 01:18:31
    filter so if we're for example looking
  • 01:18:33
    for a computer name that we just looked
  • 01:18:36
    at before which is work dash zero zero
  • 01:18:39
    zero two you would base basically do it
  • 01:18:42
    on their names start with and then click
  • 01:18:44
    ok now
  • 01:18:46
    this may not change this right side here
  • 01:18:49
    where you see things in here this may
  • 01:18:51
    not change because there are tons of
  • 01:18:53
    tons of different things in there we can
  • 01:18:55
    just right click and then refresh and
  • 01:18:56
    then it's going to find it like that you
  • 01:18:58
    see that so why would you want to look
  • 01:19:01
    this up to begin with let's say there
  • 01:19:03
    are issues where you can't connect over
  • 01:19:05
    the network sometimes you may have a
  • 01:19:07
    duplicate record duplicate record for
  • 01:19:10
    the same host name this can happen if
  • 01:19:12
    this computer connected to a physical
  • 01:19:14
    Network and then later on connected to a
  • 01:19:18
    Wi-Fi network and the DNS is kind of
  • 01:19:20
    confused to where am I going to forward
  • 01:19:23
    this you know like if it has two entries
  • 01:19:26
    for the same host name so you can just
  • 01:19:28
    right click and delete one of them now
  • 01:19:31
    make sure you delete the one that has
  • 01:19:33
    the the oldest lease timestamp on it so
  • 01:19:38
    look at this time stamp here and you can
  • 01:19:41
    just delete the one that's the older one
  • 01:19:43
    or you can just delete both of them
  • 01:19:46
    and it will come back automatically on
  • 01:19:48
    its own next time the computer is
  • 01:19:50
    refreshed next time the DNS is flushed
  • 01:19:53
    on the computer so if I right click
  • 01:19:55
    delete here I can certainly do this here
  • 01:19:58
    and hopefully it works properly
  • 01:20:02
    hopefully it works properly now so we're
  • 01:20:04
    going to work computer here the one we
  • 01:20:07
    just deleted we're logging into it
  • 01:20:11
    and uh
  • 01:20:13
    so what we have to do here is do a flush
  • 01:20:17
    DNS we're going to type in ipconfig
  • 01:20:20
    forward slash flush
  • 01:20:23
    DNS so this would basically flush all
  • 01:20:27
    the DNS records they're not they're set
  • 01:20:30
    up locally so at this point the computer
  • 01:20:32
    doesn't know that we've deleted their
  • 01:20:35
    records so if we do a flush DNS and do
  • 01:20:38
    you know basically a hit enter it's
  • 01:20:40
    going to flush this record and it's
  • 01:20:43
    going to repopulate with the new record
  • 01:20:45
    new forwarding record on the server
  • 01:20:48
    level and on the local level so that way
  • 01:20:51
    the network access to this computer is
  • 01:20:54
    working again
  • 01:20:56
    all right
  • 01:20:57
    so if I refresh here and it may take a
  • 01:21:00
    bit it may not show up now it takes a
  • 01:21:03
    bit sometimes up to 15 minutes 20
  • 01:21:06
    minutes 30 minutes uh for the new record
  • 01:21:08
    to automatically populate in here but
  • 01:21:11
    eventually it will show up in here so
  • 01:21:14
    right now remember we're filtering so if
  • 01:21:17
    I remove the filter
  • 01:21:20
    if I remove the filter
  • 01:21:24
    come on I'm trying to remove the filter
  • 01:21:27
    uncheck the filter
  • 01:21:30
    so this is what I need to do sorry
  • 01:21:33
    refresh uh it goes back to what we we
  • 01:21:37
    saw previously again that computer is
  • 01:21:40
    going to come up I don't know why I said
  • 01:21:43
    sorry this is so weird
  • 01:21:46
    it will show up here eventually again
  • 01:21:48
    once it you know gets time to catch up
  • 01:21:51
    to the DNS server so that's what that is
  • 01:21:54
    reverse lookup zone is kind of the same
  • 01:21:57
    thing uh but just in Reverse right we're
  • 01:22:00
    looking at what the IP addresses are and
  • 01:22:03
    what they are pointing to and here are
  • 01:22:06
    some old records of that here's an old
  • 01:22:08
    record pointing to your computer it's
  • 01:22:10
    called just work one
  • 01:22:11
    you know and here's the network printer
  • 01:22:13
    one that was you know added in there and
  • 01:22:17
    that's what this is this is just in
  • 01:22:19
    Reverse basically looking at what the IP
  • 01:22:22
    address is pointing to and it's it's a
  • 01:22:25
    reverse I mean I don't know how else to
  • 01:22:26
    explain it the main thing uh to
  • 01:22:29
    basically you'll be working on if you're
  • 01:22:32
    just starting to work for a company
  • 01:22:33
    you're looking for is you know looking
  • 01:22:36
    if there are DNS issues with a records
  • 01:22:39
    from when it comes to forwarding so you
  • 01:22:41
    would mostly be looking at the forward
  • 01:22:42
    lookup zones for your domain for your
  • 01:22:45
    domain specifically or maybe other
  • 01:22:47
    domains I don't know
  • 01:22:49
    I hope this is easy to understand I hope
  • 01:22:51
    I didn't make this too complicated uh
  • 01:22:54
    but um
  • 01:22:56
    yeah this this is what it is it's very
  • 01:22:59
    useful to know when you're starting to
  • 01:23:01
    do tech support for a company and uh
  • 01:23:05
    yeah I hope you find it helpful let me
  • 01:23:07
    know in the comments and uh you know
  • 01:23:10
    more videos to come again the next one
  • 01:23:12
    is going to be help desk because we got
  • 01:23:14
    50 tickets so that might be a marathon
  • 01:23:17
    on that I don't know I will see how I go
  • 01:23:19
    about that it just depends on how many
  • 01:23:21
    people are interested and uh yeah it's
  • 01:23:24
    gonna dictate how we go about this I
  • 01:23:25
    hope you have a wonderful day take care
  • 01:23:27
    bye bye
