I have a Windows Server 2008 machine on a domain that will not stay powered on. During startup I see:
"Applying Computer Settings" then "Applying Registry Policy" then "Applying Group Policy Registry Policy" then quickly flashes "Please wait for the Local Session Manager..." then quickly flashes "Shutting down Group Policy Client service..." then "Stopping services..." then "Shutting down"
It never reaches the ctrl+alt+dlt screen.
I can get into safe mode with networking and when I try to force a group policy update it says that the user policy update failed. The event viewer shows quite a few group policy failures.
