What’s a domain?

A domain is a kind of network that allows you to login to your user from any computer on the network. The network has to contain at least one computer running Windows Server and the rest of them running Pro or Enterprise Windows versions. This can be very useful in many cases:

  • A small office with no fixed computer for each employee.
  • Even if they have fixed computers, you can watch their work and give different permissions to each of them from your server.
  • A big company with a number of computer less than number of employees.
  • Universities and schools.

So, you can simply sit on any computer, login with your username and password, submit your work and logout again.

And now, all you need to join the domain is:

  • The domain name
  • A username
  • A password
  • The server’s IP (That’s to make the connection more reliable)

Your domain administrator is the one responsible of creating a user on the server computer and give you all the previous information.

We’ll begin by setting the server’s IP as your Primary DNS. Follow us:

  • Open Control Panel and search for Network and Sharing Center.
  • Click on the Connection you’re working on (Ethernet or the WIFI name).
  • Click on Properties.
  • Select Internet Protocol Version 4 (TCP/IP4) and click Properties.
  • Select Use the following DNS server addresses and enter the server IP you got as your Preferred DNS server and then click OK.

Got all that you need? Let’s join the domain then.

How to join a domain?

  • Open Settings from your start menu.
  • Select System.
  • Select About from the left pane and click Join a domain.
  • Enter the domain name you’ve got from your domain administrator and click Next.
  • Enter the Username and Password you were provided and then click Ok.
  • Select your user type: Administrator or Standard user (it’s standard user by default, if you don’t know what to pick just leave it as it is).
  • Restart your computer now or later, it’s up to you, but it won’t take effect until you perform a restart.
  • The first thing you’ll notice once your restart is complete is that your lock screen will look a little different. Enter your domain user’s password.
  • In some cases, you’ll be asked to change your password immediately, it’s a feature your server administrator might have set. Otherwise, you may ask your server administrator to change your password when you need to.
  • You will have to be a little patient and wait while everything gets ready, it’s like you’re on a new computer, but every change you’ll make from now on will be saved to this domain user and accessible from any other computer on the domain using your credentials.
  • Now you’re logged in, go to your Settings -> System -> About, you’ll see that your computer is registered on the domain now.

How to login back to your local computer account?

Now, if you want to reach your initial local files and programs stored on the computer away from the domain, here’s how you can do it:

  • Boot your computer or sign out to your lock screen.
  • Select Other user from the bottom-left corner.
  • Enter your machine name followed by a backslash then your local user. Enter your local machine password if you had one and press Enter. Here, my computer name was Win10FAQ and the default user on it was Win10FAQ so the resultant is Win10FAQ\Win10FAQ. If yours is Desktop-xxxxxx and your user is Joe for example so you’ll enter Desktop-xxxxxx\Joe

How to disconnect your computer from the domain?

  • Sign-in with your local account using the previous steps.
  • Go to your Settings -> System -> About and select Disconnect from organization.
  • Select Continue.
  • Restart now or later but you won’t be able to fully leave the domain until you perform a restart.

    I was using an administrator account in my system. Recently I connected my system to a domain. And when I tried to login to my administrator account I am unable to login. I have put my Machine name\username and Password like you said. But I am unable to login. I am sure whether my username is correct. But my password is correct. And I am able to login to the domain account successfully. Is there is a way to find out my username of administrator account? And how do I enter into my administrator account?

    Please help me with this.

    If you’ve joined it to the domain you’ll need to setup a domain admin account through active directory.
    Alternatively if you’re trying to access the local admin account you can use .\administrator (.\) this modifier directs the username to the local machine, you’ll see your domain change from DOMAIN to “Computer name”

    I just built a new Server 2012 Domain Controller in a brand new domain, created user accounts etc. I have windows 7 Pc’s and server 2012 devices on the domain
    I have upgraded the existing Windows 10 HOME edition to windows 10 PRO and successfully joined the domain.

    I am able to login the domain users on the Windows 7 and server 2012 machines, but if i try to login as a domain user to the Windows 10 machines, i get an error ” The Username or password is incorrect. Try again”
    I have confirmed the user account is active and i can even login to a win7 and server 2012 machine with that domain user name.
    has anyone encountered this? sos
