Restoring a DC after FSMO roles moved to another DC in the domain
Posted on 2010-09-23
I need some advice on a failed domain controller. This is basically the scenario of what happened.
We had an HDD failure on the primary DC and the server were taken down.
Whilst the server were down we seized the FSMO roles over to secondary DC, ensured it was a GC and ensured that all the servers point to this DNS.
We are now trying to restore the old DC from Symantic backup, but in order to do this the old DC needs to be a DC so that we can do restore in directory service restore mode. We want to restore the old DC, specifically as this were the CA server. Yes I am aware that bringing this server back into the domain can cause havoc, but we will do the restore and then before the server start back up we will unplug from the network.
My question is basically how feasible does this solution sound and if there is anyone that has done some dort of similar restore before where all the roles has been moved from the primary DC and then trying to restore the primary DC back again from backup?
Looking forward to a response.
