If I have SERVER1 with 2 drives DRIVEA and DRIVEB which are software mirrored by Win2000 and I have an uncorrupt version of . Then I break the mirror, remove DRIVEB put in DRIVEC and recreate the mirror. Then 1 day later Active Directory becomes corrupt and replicates across the mirror and to my other domain controllers. Can I then take all domain controllers off-line (or not), remove DRIVEA and DRIVE C from SERVER1 and replace them with a stand-alone DRIVEB (with the uncorrupt AD database) without any problems and rebuild my other DCs (with new names) and replicate AD from DRIVEC? I'm just wondering if this can be used for a disaster recovery situation.
