I've set up GPOs for all our computers to use an internal WSUS server to get updates and automatically re-boot if necessary at scheduled times. I've used the same GPOs and settings for Member Servers, Workstations and Domain Controllers except the scheduled reboots are at a different time. The Member servers and workstations are working properly. The Domain Controllers are not applying updates automatically. The updates apply fine if I manually click on the little windows update icon in the system tray. How should I troubleshoot this? There's nothing obvious to me in the event logs.
