DNS error with my Domain controller

When I run a dcdiag /q on my sole DC, i get the following error

the host 1423423-cc80-xxxxxxxx._msdcs.domain.local could not be resolved to an ip address. Check dns, DHCP, server name, etc.

............................ IMDC01 failed connectivity test.

I have deleted the _.msdcs records, all DNS zones, recreated DNS zones, restarted DNS services and netlogon service, which recreated all the _msdcs records. Yet same problem.

Anyone have any ideas? The dns IP is correct on the card.

This was a restore, and I believe there are issue with the recovery. How do I clean up or have the DC fixed?

I have read the netdiag /fix would do the trick, yet I can not locate the executable on windows 2008 R2 to use it.

is this an environment with just a single DC or do you have multiple DCs ?

are there any errors in the directory services event log or the file replication event log ?

Netdiag is removed from Windows Server 2008. Now, you need to use dcdiag.

Please try to run in command-line

dcdiag /fix

Does your DNS on the NIC point to 127.0.0.1?
If this is a recovery of a failed DC you may need to perform a metadata clean-up... http://technet.microsoft.com/en-us/library/cc816907(WS.10).aspx
