I have on DC called DC1 and one backup DC called DC2
Both are running Windows Server 2003 SP2
DC1 is the also FMSO holder.
I want to have another DC later with windows server 2008.
I will run Adprep on DC1 but need recovery plan if something goes wrong.
Do I need to backup both dcs system state data DC1 and DC2?
Say after run adprep both DCs give problems how can I restore my dc please explain.
