How to join a computer to the domain - End User
Posted by , Last modified by Jennifer Millan on 12 April 2013 02:07 PM

From time to time you may need to join computers to your Active Directory domain.  Normally this comes up when you purchase new computers or have an existing system rebuilt.  The computer is joined to the Active Directory domain so that it is a member of the trusted network.  Any user in Domain can then log into the PC. 

You will need to have this information prior to joining the PC to the domain:

  • Computer name you want to assign to the PC.  The PC name can be anything you want.  We suggest the first initial and last name of the user that will be assigned to the PC followed by a number (e.g. iPremise User would be IUser01 for their first PC).
  • The user(s) that will need to be local administrators on the PC.  This can be specific users or everyone.  If you want everyone, request the group Domain Users to be added into the local administrators group.

Local administrators have full access to the data on the machine.  The local administrators permissions, however, do not impact any permissions for file shares or other network resources.  They simply grant the user full access to the local machine.

Once you have the information above, email it to support@ipremise.net.  A technician will pick up the ticket and create the computer account on the domain.  They will notify you when this is complete.  Then you can continue on with these steps to join the PC to the domain.

Windows XP:
  1. Right-click on My Computer and choose Properties.  The System Properties dialog box is displayed
  2. On the Computer Name tab, click Change.  Enter the name of the computer that was set up in Active Directory, enter the domain name as CUSTNUM.local (e.g. 10100500.local). Click OK.
  3. You will be prompted for a username and password.  Enter your domain username and password which will have permission to join the computer to the domain.
  4. You will need to restart the computer for the changes to take effect.
  5. Log in with your domain credentials when you are at the CTRL-ALT-DEL screen.
  6. Click Start and choose Run.  Enter command and click OK. 
  7. In the black window, enter "gpupdate /force" without the quotes.  If necessary, reboot or log out and log back in.
  8. iPremise Support can now set up the local administrators for the machine.

Windows Vista/Windows 7

  1. Click on Start and right-click on My Computer.  The System Properties window is displayed.
  2. Scroll down to the Computer name, domain, and workgroup settings section.  Choose Change Settings.
  3. On the Computer Name tab, click Change.  Enter the name of the computer that was set up in Active Directory, enter the domain name as CUSTNUM.local (e.g. 10100500.local). Click OK.
  4. You will be prompted for a username and password.  Enter your domain username and password which will have permission to join the computer to the domain.
  5. You will need to restart the computer for the changes to take effect.
  6. Log in with your domain credentials when you are at the CTRL-ALT-DEL screen.
  7. Click Start and enter cmd in the search box.  Click on cmd.exe when it appears.
  8. In the black window, enter "gpupdate /force" without the quotes.  If necessary, reboot or log out and log back in.
  9. iPremise Support can now set up the local administrators for the machine.
Notify iPremise Support to go ahead and add the local administrators to the machine. You can call in or email a response to the previous ticket.  Congratulations!  You PC is now on the domain!
