Several of my Windows 7 client computers on our school network have been giving an error since rejoining them to the domain. I do not know if the error was occurring at the end of the school year before summer vacation or not but here is what I ran into today. We upgraded our server hardware and installed Windows Server 2008. Once that upgrade was complete I started removing clients from the old domain and joining them to the new one. All was going well for awhile until I got to several systems in the Primary Grade school building. I was able to remove them from the domain but when they rebooted the error on the screen was "The User Profile Service Failed the logon. User Profile cannot be loaded." In order to join them to the domain and in hopes of resolving this error I logged on in Safe Mode with Networking. From there I was able to add them to the new domain but I still get the same error when trying to log on to a user account. What do I need to do to resolve this problem?
