Vista Ultimate to 2003 AD Domain ---Problems

Interesting problem...set up a Vista Utimate box at home, took it to
work joined our W23K domain no problems. Tried to add several
different networked printers all failed with error 0.0000005
something. Did some research and discoverd you can't add a networked
printer to a standard TC/IP port with UAC disabled. When I enabled
UAC and rebooted the system ...no joy... system hung at "crcdisk" in
safe mode.

I my frustration I rebuilt the machine, but left UAC enabled
everything works fine until I join the domain, which it does no
problem. The problem is once I reboot I get the "configuring desktop"
message it goes away and then I get a light blue screen with just the
mouse cursor setting in the middle.

I've let it set like this for several hours thinking it would
eventualy give me a desktop ...never happens. The other strange thing
is that the local administrator accout has been disabled in AD. If I
enable the admin accout in AD I can log on locally to the box but am
still unable to get my profile or desktop wihen I try and login to the
domain.

Any one have any Ideas on this?
Thanks in advance
