I have server 2003 with Active Directory and it serves as the DNS server. It has run perfectly within our small network (a couple computers) until I put a public static IP on it. Now I have no connectivity to the DSL modem (router). The DSL modem has a public and private IP on it. The server is the primary domain controller and its DNS points to itself. The gateway is the public IP of the DSL router. It is not the connection, as I changed it back to the old IP and it then works (private IP). I remade the DNS zones to reflect the new IP's. It did not work before I did that, nor after. What am I doing wrong?
