I have a network of several old computers. It consists of three Windows 95 machines and one Windows 98 machine. Recently, I added an XP Home machine to it. The machines are connected via a hub that does not distribute IP addresses. They are all operating in the same workgroup. The 98 and 95 can still all see eachother. The XP machine can only see itself. How do I get the XP machine to see the others?
