DC Crashed after installing windows updates, I have a full backup of the C: but I don't have a system state. The Active directory appears to be corrupted.  In active directory domains and trusts there are no items to display, also the Exchange server cannot contact a domain controller. Any help that you may provide will be greatly appreciated. We are in a work environment and people are highly dependent on their e-mails

Do you have another domain controller available, even if it is on a different site?

I have one on site but it seems to have replicated the corruption. I have a full backup of the c: on the original DC however I am unsure as to whether it has a system state backup included in the backup . To Answer your question yes we do have another domain controller, but I would prefer to fix this one if possible.

From the command prompt, change your directory to the directory that you have your SupportTools on. (If you don't have them, you can get them from the 2003 Server disk). Once in the right directory in the command prompt, type: dcdiag.exe and hit enter. (If you are already familiar with dcdiag - I apologize as some are not).

See from the results of the diag if there are any problems that stand out.

It may be easier to remove the DC from the AD, rebuild it, then dcpromo it again. oBdA suggested these links to remove the Dc from the AD. At least then you would be sure the AD was intact, rather than risk the corruption spreading to your good DC.

How can I delete a failed Domain Controller object from Active Directory?

It could be something like permissons if it is replicating. either way I wouldn't want to risk it contaminating the rest of th directory.

Do you have a backup copy of: c:\windows\ntfrs...? If so, suggest replacing the current file with it...then demoting the dc and promoting it back again.
