I have installed a single 2008 R2 server as an Active Domain Controller and when I run the Best Practices Analyser I get the error - " DNS servers on Local Area Connection should include the loopback address, but not as the first entry". I have set DNS1 to the computers IP '192.168.1.199' and DNS2 to the loopback '127.0.0.1'. I'm not sure what the error message means. Does it mean I should set DNS1 to an external DNS address? There is only one DNS machine on this network so any other entry would have to be external. When I do that I get many more errors.
Can anyone tell me what I'm missing in this configuration?
