Unplanned change of Credentials

URGENT!

Running server 2003 std. w/latest srv pack and updates.
 
We have encountered a very mysterious problem.
Our fileserver was working with the shared folders policies etc., however a sudden change occured without having interacted with the server. On logon attempt to one of the shared folders mapped as a drive, we were prompted for credentials. This never was an issue before, and what baffles us the most is, that the credentials entered arent accepted. No errorcodes are displayed, the credential boz just remains prompting us again and again.
Another mystery occours when trying to connect to another share. The credential box looks different, being that the username field is grayed out with the servername\guest entered. Our guest account is naturally disabled so we are wondering where in the world that derrives from. No code admitted will work ofcourse. What went wrong? Up til this error, we have done nothing, not updated, not installed nor tampered with the server, and yet the problem still occured.

TIA
