When a Primary Domain Controller machine fails, it really helps to have at least one Backup domain controller so that Active Directory Users in the network may continue using the domain. However, most shared fodlers and files also reside inside the PDC and if the PDC machine itself is rendered physically unusable, these shared folders and files would also be unusable to domain users even if they could still log on to the domain thru the BDC. So to speak, should a PDC physically fails, the only way to allow domain users to have access again to those folders is to rebuild the PDC from the backup tapes. Would somebody advise on how to rebuild the Active Directory list for the PDC from a BDC machine in order that a manual recreation of the Active Directory wouldn’t be necessary? And how about the access privileges on the domain folders and files, will there be a way to recreate these automatically?
