You're a bit sparse with information here. When does that error show up? On which Windows version(s) does it show up? What is the exact error text in the event viewer?

At which occasions does this error occur, and is there anything else running on that machine (Exchange, IIS, ...)?
I'm afraid I have no real ideas at the moment; check out those maybe:

The server is a DC, with Wins secondary, dhcp, and global catalog, file and print sharing as well.

The link to the eventID.net  helped me to better troubleshoot the issue, because users were prompted to change their passwords.  :)
