On one of my Windows 2000 Server DCs, the event "Windows cannot determine the user or computer name. Return value (14)." with Event ID 1000, Source Userenv shows up about once every few weeks. When the event shows up, the server becomes more and more unresponsive; printer queues, file shares, etc. stop responding (over the network). If the system is not rebooted from the console, it will eventually become completely unresponsive, and a hard reboot is needed.
What can be done to solve this problem?
