I configure DNS on Windows 2000 Server, what should the settings be on the NIC for DNS on the DNS server. I see by default it is set for loopback. Is there any reason why I wouldn't want to change that to my DNS servers IP address. if you change it to the DNS servers IP, you can't replace it with the loopback address. ANY IDEAS??

The DNS service running on this server is set up for any other machine that references it in their DNS server settings. The DNS IP setting in TCP/IP properties on the server itself is for users that go to the internet from the DNS server itself. If this server is going to be used only for DNS resolution and not for maintaining records for web/ftp/mail servers you operate it is fine to leave it pointed to itself, and in fact will be faster once a sizeable amount of cached sites have been builtup in the DNS database.

The only reason you would want to change this is if this DNS server resides on a public subnet and the users that reference it are on a private (10., 172.16., or 192.168.) *AND* if the DNS server is referencing a webserverthat is on the private IP with its public address. Because of the peculiarities of NAT and routing this setup wouldn't work.

Hope that helps,
