I have two Domain Controllers, Windows 2003 Active Directory. I have Domain centric roles (PDC,RID, Infrastructure) on DC01 and Forest Centric (Schema master, Domain Naming Master) on DC02. Both run DNS with forwarders to 220.127.116.11 and 18.104.22.168> WHich one should be used as my primary for clients? or does it matter. Alson what order should they be on each other should DC01 point to itself or DC02 as the primary and vice versa.
