Since the time change last Sunday we've found that on some of our Windows 7 SP1 clients the Computer Configuration policies are not being applied. Our DCs are all 2008 R1 Enterprise SP1. The first sign of this is our users need to press Ctrl+Alt+Del before they can login since we've specified "Interactive login: Do not require Ctrl+Alt+Del" = Enabled.
So the user logs in, we run rsop and there's a red "x" on Computer Configuration. If we right-click > Properties > Error Info tab it says
The confusing part is the time in the system tray is correct, but the time in this dialog is 1 hour behind. We have confirmed the time on the DC is correct.
Ideas?
