Yea, I installed all the drivers at once without a reboot, installed them one by one and rebooting inbetween each driver install, no go. I even used HP's supplies XP disk and still had the same issue.
I finally finished installing all the security updates via rebooting after each single update. Everything was fine. I've came to the conclusion that when I join the pc to the domain, somthing is hammering the profile rendering it useless. All the same error and missing icons, etc happen all over again. So tonight, I will take it home, reinstall update everything at once, and then join it to my domain and see what happens.
