We experienced a power failure last night that caused all of our DCs in our forest root domain to go down. After booting everything back up, AD refuses to work correctly for the entire enterprise. AD, DNS, DFRS, NETLOGON, Kerberos, Intersite Messaging, etc services all start and stay running.
However, DNS will not function because it cannot talk to AD, and AD won't function because neither server can contact a domain controller in the domain. Of note is DNS event id 4013 "The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller..."
Server 2008 R2, all DCs in our enterprise are GCs.
I feel like I've dealt with this before, but cannot recall how to "trick" AD and DNS into starting up on either server without first talking to another DC in the domain. Any help would be awesome.
