Some of our users are getting new profiles created when they log in to the domain, and of course they don't see the desktop they're used to, etc. These are local profiles, not roaming.
Our users all log in using our domain name in the login screen (user;password;domain). Their existing profiles are shown in Documents and Settings as 'username' and the new profile being created is 'username.domain' (so even though they've been logging into the domain for months, the profile being used does not have the .domain extension) . The existing profile has been in use for a long time, but on random days and random pc's, a new profile gets created.
It seems all of the effected pc's are Windows 2000 pro sp4. Our original domain controller is Windows 2000 sp4, and we added a second DC running Windows 2003 sp1 in January. Everything seems to be running fine from the DC standpoint - dcdiag shows no errors. The login script seems to run properly, as all their mapped drives appear.
Re-creating the users old profile is getting annoying.
What is causing the second profile to be created and how do we stop this behavior?
