An application server running on Windows NT 4.0 Workstation used to login using a domain user account and authenticate to a Windows 2000 Server. When that server's RAID array began to fail, a new PDC running Windows 2003 was installed. The old failing server is still in place. The domain name remained the same.
After the changes, I am no longer able to authenticate at the NT4.0 workstation. Upon startup the machine reports that "No DC is available to authenticate, cache values being used" or something to that effect.
I need to keep this NT4.0 box limping along for a little longer. I suspect that when the 2003 Server was promoted to PDC, that it doesn't by default allow authentication from the NT4.0 workstation.
Is there a means of allowing it?
