I have a Windows 2000 server which was running fine until a UPS problem this morning caused it to cut out. When it finished booting back up 5-10 minutes later, ALL of my Windows NT workstations started giving the error "The system could not log you on to this domain because the system's computer account in its primary domain is missing or the password on that account is incorrect" when anyone tries to log on. The WinXP stations are fine.
I have tried..
Restoring the C drive plus system state from backups (I tried both last night's and a two week old backup. Though before it died, the server hadn't been rebooted in 3 months so who knows what setting might have changed that didn't take effect until today's reboot).
Making a workstation leave the domain, reboot, rejoin the domain, reboot again. Same error.
netdom query /domain:[domain] /reset /workstation - Goes through each station reporting "The trust relationship between this workstation and the primary domain failed." That's the Win2000 version on the server
netdom member [workstation] /joindomain - This is the NT4 netdom. On the Win2k server it reports that the RPC server in unavailable on the workstation. When tried on the workstation, it appears to work but after rebooting the machine, I get the same "system's computer account missing/password incorrect" message.
Based on what I've read, I really don't understand why all NT machines would fail at the same time. Has anybody got any ideas? I really don't want to have to go around 100+ NT machines installing XP on them.
Thanks in advance
