We have one office with a seperate windows 2003 server acting as a domain controller. This morning it would not boot up and there was an error message "system32\config corrupt or missing". When we booted using Recovery Console we discovered that the 'default' file within the system32\config folder was missing. We managed to replace the missing file with a copy of the default.sav file and now the server boots up but not as a domain controller.
Is there any way of restoring the domrain controller settings or do we have to run dcpromo again and recreate the active directory? We do not have any windows back ups to fall back on, although our files are backed up elsewhere (even though these seem to be in tact)
Any help would be gratefully received
