Alright I do not understand what is going on here. I am onboard a vessel that has internet on it. The domain server is also the DHCP and DNS server for this network. When I go to the client PC and open the network connection settings they are configured automatically. So I change them to set the ip address / subnet / default gateway / and dns server and the internet works. If I take the DNS server out, internet will not work. Also if I disconnect the server, internet stops working on all client computers. Why do you think this is? I even plugged one of the client computers into the same port on the switch that the server was plugged into just in case that port was configured in some way and still nothing. I need to take this server down to rebuild it and I cant have them with no internet while I'm doing it... Any ideas? Why do these computers require this server to get internet?
