I've got a very new primary domain controller (Windows Server 2008 R2) experiencing a crucial issue. I ran a Windows update today and restarted the server. After restarting, the primary domain controller gets stuck for about 10 minutes saying "please wait for the group policy client". The server eventually loads into Windows, however, the server's time is about 8 hours off and the active directory info is basically missing. I checked the server's DNS and it points to itself only. I then checked out the DNS service on the server and that doesn't work either, which explains the missing Active Directory info. I have a backup domain controller, so I configured the NIC with that as the secondary DNS and DNS & Active Directory immediately restored.
I've tried removing the DNS role and adding it back, but that didn't help.
Any ideas would be appreciated. Thanks!
