I am running SBS 2003 and using it as DHCP, exchange and a domain controller. It is a farely powerful system with 2GB RAM and a 3.6GhZ CPU. It only has 3 client computers connected and after installing exchange and setting it all up I decided to do a reboot as exchange was playing up a bit. I haven't even got to the logon screen yet and it is at a screen saying "Applying computer settings", it has been on this screen now for about half an hour and I don't know if this should happen. I have tried restarting it again by using the button on the case as I thought it had simply hung, it is at that same screen again. Should it take a long time to start? Any ideas anyone?
