I have one DNS server setup internally in my 2003 domain using AD. All the clients in the preferred DNS entry have the IP address of my DNS server in them and nothing else. The local suffix is also filled in. On the DNS server under Local Area Connection, the only DNS IP address entered is it's own. I have a pointer I created called Internet that has the IP address of external isp dns server. All clients and servers have internet access when the preferred dns entry is my local server. I just want to understand why? Is the pointer named Internet the reason? How does it know where my gateway is?
