i do have 2 computers connected via modem/router.Both have internet connections of which one is getting via usb, the other one is through lan cable.I would just like to have access from the other computer with nba game installed on it.I want one to play nba games too thru the one which has it installed on it.or i want even to set-up a peer-to-peer network so one another can do file transfer and other network stuff.Thanks in advance.

The first thing you should do is assign and IP to each computer if your on a router. once you do this just go to start>run and type //192.168.1.2// or whatever the IP of the computer is your trying to access. Also make sure you have a folder or drive shared so the other computer can access it over the network.

Thank you.
