User logs into PC with same credentials and into same domain daily. Today user performs same login and windows creates a new profile for existing user. I have seen it create a username.domain profile and today it created a profile named TEMP. Had the user log off and on and it was back to the correct profile. Why is this happening? We have been on a Windows 2000 domain for the last 3 years and this just started happening in the last couple of months. Also has happened on both W2K and XP machines. Can someone help?
