We have an active directory domain that consists of about 15 workstations (windows 2000, and a few xp), and a server (poweredge 2600, running windows 2000 server). Last friday morning, all of a sudden, every computer started taking a long time to boot; It stays a few minutes in the "applying computer settings" screen. After typing in the username and password, it gets stuck in the "loading your personal settings" screen for about 10 minutes before it shows the desktop and finishes starting up.
Now, i've read other threads and mostly everybody seems to agree that this kind of problem has to do with a DNS error/misconfiguration. But i'm not sure if we are experiencing DNS issues, because we have not changed any settings on either the server or any of the workstations.
Does anybody have any suggestions as to what I can do to troubleshoot this problem?
