The solutions from below are independent from each other and I really hope they will prove to be helpful to you.

  •  Try to delete the existing computer account in Server Manager, recreate the computer account, synchronize the domain, and then on the client rejoin the domain
  • Reset the local administrator password and then log off and on as the local administrator to test it. Then change the domain to a workgroup member instead, restart as prompted, log in as the local administrator and then rejoin the domain
  • Log into the AD, go the AD Domains and Trusts area. Find the domain, right click on it and go to manage. Then find the machine in question under the Computers tab, right click it and then Reset Account.  After that, try to logg in the user on the client machine in question
  • Remove the computer account from AD in the Users and Computers snap-in on your DC or mgmt workstation. Then manually add the computer account from the Users and Computers snap-in on your DC or mgmt workstation.

These fixes are also available for Windows 7 and Windows 10, so be sure to try them:

  1. Insert the original installed version Windows Vista or Windows 7 DVD. Keep in mind that must match the current installation. It won’t work if a Windows Vista x64 installation DVD is used for a Windows Vista x86 installation or vice versa. Same rule on Windows 7.
  2. Reset the computer and boot from the DVD.
  3. Choose option Repair your computer.
