I just replaced our two old 2003 domain controllers with new 2008 DC's.  Both are GC's and both run DNS for our local domain.  I keep reading conflicting opinions on what the proper DNS settings should be in the network settings for each DC.  Should each DC point to ITSELF as the primary DNS server and the other DC as it's secondary?  Vice Versa?  Should the server's own IP, whether it's primary or secondary, be the actual IP od the server or the 127.0.0.1 address?  Thanks.
