I have a client using SBS 2011 server with about 12 users. After a power issue that caused the server to restart without a graceful shutdown. All of the active directory user accounts no longer exist and the domain integrated DNS zone for the local domain won't load.
When I try to open the "SBSUsers" OU in AD users and computers snap-in I get the following error:
"Data from SBSUsers is not available from the Domain Controller Servername.domain.local because:
An operations error occurred."
All of the other OU's open and I can access any other user accounts, groups and computers.
The DNS issue I assume is tied to the problem with AD. I get an error:
"The DNS server was unable to complete directory service enumeration of zone domain.local. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it"
I have run a chkdsk /f and the drive came back clean. I assume that I will need to try and do some type of repair on the AD database but I could use some help pointing me in the right direction to get started. Unfortunately, I don not have a valid system state backup so if the repair doesn't work I will have to start from scratch.
I would really appreciate some help at least trying a AD repair before I do anything else.
