User Profile keeps loading TEMP Profile

I am having a difficult time with an issue that our support staff won't support (as they will not support Vista). I am able to log into our domain without any issue, however, when I go home and log into my domain account (disconnected), everything works great. I log out that night, redock my computer on our domain network and BLAMO, I get loaded into a TEMP profile.

When I look under the event view, I get the following messages. There are 3 others that follow it, relating to this event, however, I don't want to spam the threads unless you deem it necessary.

I'm just frustrated that I can't get support and most of the search articles I came across had to do with local accounts. I did make a backup of the "functioning" profile, in hopes to restore that once everything is back to normal.

I've logged in as a local admin to the box and renamed the "corrupt" profile in hopes that it would simply be rebuilt when I logged back into my domain account. However, when I did that, it STILL logged into the TEMP profile…grr!

Thanks in advanced,
Aaron
