Upon booting up the server after shutdown for the weekend, the system boots normally, the login screen is normal, but when you enter your name and password and hit enter, the screen goes black. I can bring up the task manager and log out to try logging in again, but get the same thing. The network seems to function ok as all the workstations and printers are working fine. Tried rebooting 5 times, no good. Even tried the revert to last known operating system, no good. Tried to repair with NT setup disk, but it could not read the emergency disk and says it can not find nt on the hardrive. Don't know what else to try, Any Hints???? Also tried to login with different users, same thing, but on some, if the background was set to a pattern the pattern would come up, no icons are any other features.
