Bear with me as this is the strangest thing I've seen. We have a user on the network I'll call "fred". He logs into 3 different machines. All have been working well for the last 6 months. Suddenly, it's like he's never logged in before. All 3 machines start him off with a fresh profile. We are on an AD domain I'll call MYDOMAIN and on a PC I'll call PC1. He log on to PC1 as MYDOMAIN\fred. He gets a whole new profile. I log in as local admin and look around. This is what I find: Documents and Settings folder contains these folders: fred fred.MYDOMAIN fred.PC1 All of his documents and desktop items are found in the "fred" folder. In user accounts, there's a local user called "fred". How could he have possibly logged into the "fred" account? Although there's a local user called 'fred', it uses the folder 'fred.PC1'. My only guess is that someone snuck in here and joined all 3 machines to the domain. But they've always been joined to the domain. He says he always logs in as 'fred', under our domain. He could be mistaken and logging in as a local user in the past but if he was, that would use the fred.PC1 folder, not the 'fred' folder. I can just transfer the one user profile to another but much of his software becomes unlicenced because he changed user profiles (for whatever unknown reason). It's a real mess but I can't figure out how he logged in as 'fred' in the past and why suddenly all of his machines are behaving that way. Anybody have any thoughts on this? Thanks!

I assume you have checked in your AD where does fred profile points to? can you check the folder details of FRED, when was it created?

The 'fred' user folder was created on July 9, 2009. The newer one's (fred.MYDOMAIN) were created today. His AD user account doesn't specify a profile location.
