I have a Windows NT 4.0 workstation that I cannot upgrade due to an application issue. We recently upgraded our Domain Controllers from Server 2003 to 2008. About 3 weeks after the upgrade of the Domain Controllers we had to reboot the NT Workstation and get the followig message "The system cannot 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.". I have removed and been able to rejoin the domain. However each time I keep getting the same error. I have tried resetting the computer account, and recreatling the DNS Entry, no luck. Any suggestions?
