In an environment running mostly client 4.91 SP3 or SP4 on XP-SP3,
suddenly -- apparently after years of working fine -- a number of
machines couldn't automatically find the right server to login the other
morning. Typically the tree & context are filled in on the workstation,
but the server field is blank; nonetheless, the workstations have never
had a problem logging in to the right server.

What could possibly make it change abruptly, for multiple users, so that
the server can't be automatically found, and therefore users can't login?

Once the server name was filled in manually, users were able to login
.... but what might have started this?
