I have a customer that has an existing Windows 2000 server setup. I believe that DNS is setup incorrectly on this server. Most machines have the IP Address of the server as thier primary DNS server, and the ISP DNS server as thier secondary DNS server. Sometimes these machine are unable to connect to the Internet. It is my understanding that you only want the server IP in the DNS setting and then you let the server do the rest. What is the proper way to do this?
