The trust relationship between this workstation and the primary domain failed fix
Recently, somebody has complained on the Microsoft Community forums about this problem, saying the following: ” ‘The trust relationship between this workstation and the primary domain failed; ” What may be the reason for this error. Rejoining the domain will solve this issue for some days, then again this problem re-appears. Is there any solution?” Upon looking online, here are the fixes that I managed to find.

How to fix ‘The Trust Relationship Between this Workstation and the Primary Domain Failed’ Error

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

  • Try to log on locally as a local administrator. After that, go in the Network tool of Control Panel, select Change and enter a Workgroup name, leaving the domain. Then restart the computer and log on locally as a local administrator.

    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, ;og 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 clicked, and “Reset Account”.  After that, try to logg in the user on the client machine in question
  • Remove the computer account from AD from 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. Be careful so that while adding the machine back to AD enter the domain username of an account that can login the machine as a member of users that can join this computer to the domain. Then go to the computer with the issue, login with username, then add it to the domain from the PC

Albeit they are available for Windows 7, you can try these fixes, as well:

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”.

4. Start command prompt.

5. Type “ C: ” or “ D: ” (Some systems have a recovery partition on C:) and press ENTER.

7. Type “ copy Utilman.exe Utilman.exe.bak ” and press ENTER.
Type “ copy cmd.exe utilman.exe ” and press ENTER.

8. Type “ exit ” press ENTER and restart the system.

9. At the login screen, press the Windows Key + U, this fire up cmd.exe window.

10. Type “NET USER” and press ENTER. A typical output like this will show:

User accounts for \\WORKSTATION
Administrator ASPNET Owner
The command completed successfully.

11. To change the password of the Administrator user, type “NET USER Administrator password”. Change password to a desirable password, like: 4dm!n123 and press ENTER.

12. Now, back at the login screen, login as Administrator. If the logon fails with “account disabled” output, try again with other username. Please refer to step 10 to see other accounts available.

13. Once inside Windows, right-click on the Computer icon and select Properties. Click on “Advanced System Settings” and in the System Properties dialog window, select the Computer Name tab and click on “Change” button. Select “Workgroup:” in the “Member of:” section and enter CONTOSO. After applying changes, restart the system.

14. After system reboots, login again, and join the domain CONTOSO doing the same on step 13. Instead of chosing “Workgroup”, choose “DOMAIN”. After applying changes, reboot again, and logon with your DOMAIN credentials.
