I have a W2K Server that gives the error message(The system cannot log you on due to the following error: The network request is not supported.) I have to reset the server for the error to go away. I can then log on and it will work fine for about 3-5 hours and then I will start getting the error message again and cannot log in Also when I can logon, the event viewer logs are blank. I did do a virus scan and a spyware scan. It found a minimal amount of spyware (couple of registry entries) and on the virus scan, no viruses.
