I have multiple lan segments with Novell and Nt 4.0 servers on them. The Novell servers have no problem seeing each other accross the routers, but the NT 4.0 servers cannot see each other accross the routers. I can ping the individual machines and can find them by ip address, but I cannot locate the domains. I have two domains on one lan segment which can see each other fine. Can anyone tell me what protocols need to be passed by the router besides tcp/ip?
