I have a small network of 8 computers connected to the internet through a linksys BEFSR81 router. One of the computers on the network is running Win 2000 advanced server and is hosting a domain with active directory. All of the computers behind the router can log into the domain with no problems, but any computers that try to connect to the domain through the internet are unsuccessful. This is all being attempted on a university network. I have the router setup so that the domain server (win 2000 advanced server) is registered as the DMZ host. If I type the ip adress of the router into the search function on a computer outside of the local network, I can find it, and can even access files on the server, but I cannot log into the domain. Every time I try to change the domain of the computer in the network ID properties tab, it comes up as non-existent domain. What am I doing wrong?
