| raju pun, not sure I follow just what you want to do. Are you trying to connect 3 machines together in a network so each can be used independently?|
If so, you can do that with an XP machine acting as a router. The big drawback to that is that the XP machine must be 'on' in order for that to work. A far better solution IMHO is a dedicated router, either wired or better still wireless.
