Ed Bott’s Microsoft Challenge–8/31/00

A Windows 2000 network admin is baffled by an overload of Event Viewer errors. Can you help? The errors appear several times a day in the Application Log and always take the following format:

Source:Userenv
Event ID: 1000
User: NT AUTHORITY/SYSTEM
Description: Windows cannot determine the user or computer name. Return value (1722).

The system in question is properly joined to its domain and has no problem accessing shared network resources. He can’t find any sign of this error in the Knowledge Base. I’ll give special preference to anyone who can provide links to comprehensive resources that he can use to decode other Event Viewer messages.
