This seems to a be a problem effecting many institutions where a computer will one day be working fine and the next day not appear to be connected to the domain. When you try and log on you get the message:
The trust relationship between this workstation and the primary domain failed.
If the computer has some software issues or doesn’t shut down properly, Windows 7 can initialise and automatic start up repair. It runs through and tries to fix issues preventing the computer from starting up. If at this point system repair finds issues and fixes them it is highly likely it will have removed the trust relationship between the computer and the domain. Essentially the startup repair causes the computer to lose its trust relationship between the workstation and the domain.
If you wish, you can prevent the computer from using the automatic startup repair:
You need to run this command on the computers in your domain: C:\Windows\System32\REAgentc.exe /disable
Here is some simple visual basic script (vbs) that you can run to disable the startup repair:
On Error Resume Next
Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run "C:\Windows\System32\REAgentc.exe /disable"
