I have about 10 computers that are going to a Blue Screen of Death when a user logins. All of the machines are connected to a Windows 2000 Active Directory Domain. We are using roaming profiles. After some troubleshooting, it seems to be associated with user accounts somehow. I have replaced one of the computers with a brand new computer running Windows XP SP3. It worked fine yesterday and now it is blue screening again. I'm about ready to start deleting user profiles etc. but wanted to see if there were any ideas out there. Thanks in adavance for your help.
