No Login Prompt (XP)
So I have about 150 computers on my network and for some reason some of them enter a state (While no one is logged in) where there is no login prompt and no amount of ctrl-alt-del fixes the issue. Once I reboot, everything is fine and someone can log in however, the next morning the same issue is present. These are all baselined from the same image and all machines receive the same updates (Microsoft, 3rd party). This is becoming an issue as all the users are complaining and it is affecting my ability to update the machines. Any thoughts?
