Lost domain controller and need to add exchange back to domain
Posted on 2011-03-12
I have a network that had only one domain controller, 2003 standard, and one exchange server 2003. The domain controller died by having 2 drives of a 3 drive raid go out at the same time. The server is dead and no chance of recovery by backup and will need to be rebuilt. I did have a secondary DC that was offline for probably 3-4 months and was scheduled to be replaced with new HW. I have brought the backup DC back online and have reset and added all servers and workstations back to the domain. All servers and workstations are working fine now but I still have the exchange server to go. The DC does have all the users and groups and the AD is in good shape.
The backup or second DC was and is a GC but was not running the FSMO roles. I will need to do the metadata cleanup and assign the roles to this DC and then add the exchange server back to the domain. I do have a solid backup of the mailbbox store.
1. what's the best way to reassign the FSMO roles to the secondary or other DC i resurrected? Can i do it through the AD MSC in the properties or do I have to go through the metadata cli?
2. How do i add the exchange server back to the domain? Should I do the metadata cleanup first or can i just remove the exchange server from the domain into a work group, reboot, then add back to the domain and reboot like the other servers? I would like to do the exchange server first before the FSMO role cleanup as the longer I wait, the longer the email server is offline.
