Have networked 3 computers and all can see each other, but only 2 are able to share cable (Road Runner) connection.I have all 3 connected to a hub and the cable modem connected to the uplink port of a router. I am figuring the problem is in the configuration of "something" , but I have it set up the same as the other client. It has a 3Com etherlink III 16 bit ISA adapter, which is about 4 years old. Wondering if updating these drivers would help? Keep getting "can not find server or DNS error"
