What are the correct settings for DNS for server 2003 when have a secondary DNS server? I have a Windows 2000/2003 Domain running DNS, WINS, DHCP with two different subnets. I have one DNS server at each subnet. I am not an expert at DNS, but would just like to know if I should have both DNS and WINS running and should I have a DNS server at each subnet or Primary and Secondary DNS on the same subnet. I paid a geek to help set this up but have had problems ever since. IP addresses are not updating or refreshing properly so some setting is not right.
