I have 4 Windows Server 2008 Domain Controllers (all the same Hardware/HP Proliant Server) on my single Domain network. I read the Microsoft Technet article (http://technet.microsoft.com/en-us/library/cc816584.aspx
) about Backing Up Active Directory Domain Service, but I wanted to ask the experts if this was necessary since I have 4 Domain Controllers that replicate with each other.
I have three quick questions:
#1: What would be the best practice with Backing up these Domain Controllers, and how would you have it set up.
#2: Also, lets say that one of the Domain Controllers crashed, how would I get it back up and running? Would I use the backup I created from the Technet article, or would I start from scratch, then have that server rejoin the domain and replicate with the other Domain Controllers?
#3: What if the Domain controller that held all of the roles crashed, what would be the best way to get him back online.
I would just like to know what is the quickest, safest, and easiest way to get a Domain Controller back online after it has crashed.
