I am working out DR scenarios and one was making me scratch my head:
Currently our domain has a 2008R2 DC and a 2003R2 DC. I know bringing restoring DCs can sometimes be harmful to an AD if others are there already in place. I have already gone through the AD prep steps to prepare the domain for the eventual move to a 2008R2 native domain but have not completed the process. Right now the domain is in 2003 native
In the event that the 2003R2 DC fails, should i recover it or just delete it from the domain? If I did restore the server from a nightly backup and brought it back up, what might the result be? Should I even attempt it?
I should note that all the domain master rolls have been transferred to the 2008R2 DC in preparation for the move. The 2003 server holds no Operations Master rolls but it is a GC.
