I have several computers that after being off the network for a period greater than 6 months, I cannot log back into them on the network as a Domain Admin. I get an error message that states "The trust relationship between the workstation and the primary domain failed".
I have read that to correct this problem, you would need to remove the computer from the domain by changing from the domain to a workgroup, and then changing is back.
Here lies the problem. The Administrators account on the machines has been disabled by group policy. I cannot get logged into any of these machines.
How do I rejoin these computers to the domain? How do I log in locally when the Administrator account has been disabled. If I change the GP so that the Admin account is not disabled, does it return to an enabled state? Also, I read somewhere that if you log in using Safe Mode that that Administrators account is automatically enabled, but it still show disabled when I tried it.
