we had a power outage twice and this is the result.

the main domain controller is broken.
ERROR[/B]:
-WINDOWS CANNOT OBTAIN THE DOMAIN CONTROLLER NAME FOR YOUR COMPUTER
NETWORK. (THE SPECIFIED DOMAIN EITHER DOES NOT EXIST OR COULD NOT BE
CONTACTED. ). GROUP POLICY PROCESSING ABORTED. -
*THE SECOND DOMAIN CONTROLLER IS GIVING THE SAME ERROR*.

BOTH ARE UP AND WORK, BUT REMOTE DESKTOP DOESNT WORK (BECAUSE AD IS
BROKEN TOO), AND MAPPED DRIVE TO CLIENT WORKSTATIONS ONLY WORK IF I
MANUALLY ENTER MY ADMIN CREDENTIALS.


[B]I RAN DC DIAG:

Domain Controller Diagnosis

Performing initial setup:
* Verifying that the local machine CAPSER13, is a DC.
* Connecting to directory service on server CAPSER13.
* Collecting site info.
* Identifying all servers.
* Identifying all NC cross-refs.
* Found 2 DC(s). Testing 1 of them.
Done gathering initial info.

Doing initial required tests

Testing server: Default-First-Site-Name\CAPSER13
Starting test: Connectivity
* Active Directory LDAP Services Check
The host
5b8046ce-3d47-4d21-bb7a-6485ssssb83._msdcs.CA1.CAPACITY could not be
resolved to an
IP address.  Check the DNS server, DHCP, server name, etc
Although the Guid DNS name

(5b8046ce-3d47-4d21-bb7a-6485ssssb83._msdcs.CA1.CAPACITY)
could not be

resolved, the server name (CAPSER13.CA1.CAPACITY) resolved to
the IP

address (192.168.7.20) and was pingable.  Check that the IP
address is

registered correctly with the DNS server.
