    Is DNS scavenging enabled? Are dynamic DNS updates working?

    Yup, we had it when I found that DNS scavenging hadn't been turned on. Check your DNS settings - this may also be causing some other oddness around the place too!

    Once you have done the above use nslookup util to confirm that the hostname / computer name is resolving to the ip address that it should be and not someone elses computer.

    Does this happen on all machines or just yours? Could be an "ipconfig /flushdns" resolves your issue as the stale record is cached on your machine.

    If not, maybe a static record is in DNS that is causing your problems? "nslookup" is your friend.
