OK...I've read the articles and the consensus is that it's OK to use the loopback OR the actual IP address on the DNS settings for the IP properties of the DC's network connection as long as the loopback isn't at the top of the list. But what about putting the actual IP address of the DC you're configuring at the top of the list? I've inherited a couple of Windows 2008 R2 servers that are both DCs and the guy who set them up is using each DC's IP address at the top of the list of DNS servers in the TCP/IP properties and the IP of the other DC as secondary.
If it's not OK to list the loopback first, why would it be OK to list it's own actual IP address first?
