I presume that you are talking about the network setting on the server hosting the DNS server. Either use the server's IP address for the DNS entry or else 127.0.0.1; either will work.

Do not leave this setting blank.

Do what ijack said, but don't set the loopback address as the primary DNS server.

Could you expand? What is wrong with using the loopback address?

Tony missed that the asked about dns entry was for a dns server.

You are correct with having the dns server point to itself for dns

No I didn't miss that, I assumed (wrongfully) that this was also a Domain Controller. If that was the case:

DNS: DNS servers on <adapter name> should include the loopback address, but not as the first entry

This does appear to be a issue with 2008 server and windows 7. I know I never had a problem with 127.0.0.1 as dns in tcp/ip properties with 2003 and below servers.

I suspect it also does not pertain to SBS since it is a standalone DC


The inclusion of its own IP address in the list of DNS servers improves performance and increases availability of DNS servers. However, if the DNS server is also a domain controller and it points only to itself for name resolution, it can become an island and fail to replicate with other domain controllers. For this reason, use caution when configuring the loopback address on an adapter if the server is also a domain controller. The loopback address should be configured only as a secondary or tertiary DNS server on a domain controller.

What I find a bit amazing about this is replication should be pulling from AD and not from a local ip address listed under the local tcp/ip properties. Name resolution shouldn't involve the local tcp/ip properties.

Not sure how it works I guess. If I had to guess I'd say it probably queries DNS for an SRV record.
