Do I have to have a registered domain name in order to make RWW or VPN work on SBS 2003. We just have a SBS 2003 file server LAN with dsl internet connection. Phone line to modem to router. All computers including server are connected inside the router's LAN connection ports with workstations connecting through a 7 port switch to the router. The server has a 192.168.x.x address and one NIC.
