User setting forgotten

I have just done a clean install of Vista U, including formatting the HD. I
have installed ffice 2003, and done online update on both.

I added the computer to the domain, logged in and setup up my Outlook
account and my Desktop. The problem occurs when I log out and log back in -
Vista has "forgotten" all my settings. My desktop is back to default, when I
start Outlook it start the first time installation process again.

I have tried this several times, I have even started from scratch and
reinstalled Vista and Office and get the same results.
