Hey guys - I am running two domain controllers (just added the 2nd one recently). The 'first' domain controller is 2003 and uses itself for DNS of course, and has forwarders set up for the iSP's DNS. All clients currently use this machine for DNS. The 2nd domain controller (2008 R2) uses itself for DNS. What other DNS settings do I need to change? Should I point the clients to the 1st or 2 domain controller for DNS? Thanks in advance for any help!
