Might be a bit of a long shot but I'm stumped, along with the ICT Manager for the school I'm working it.
In one of the IT rooms when you switch a computer on it will boot through BIOS fine, but when it gets to "applying computer settings" it can hang for a long time (~15 minutes). If you unplug the computer from the network it starts up fine, gets to the login screen, then you can plug the network cable in and it will work fine.
I don't think it's anything to do with the fact we've been coming close to running out of IP addresses or a problem with our DHCP. Microsoft KB says apply the latest service pack, which we've done, and check a service.
Servers and domian controllers are S2003, Computers and Desktops are XP.
Does anybody have any thoughts on what to try?
EDIT: The logs have shown a problem with folder re-direction for mapping My Documents to the "U" drive.
