If you’d like to connect two or more computers via LAN, then you should utilize the Network Bridge option provided in Windows XP. There is no configuration required and you do not need to purchase additional hardware such as routers or bridges. IP addressing, address allocation, and name resolution is highly simplified in a single subnet IP network.
To use this feature you have to do this:
1.open Network Connections.Under LAN or High-Speed Internet.
2.select each of the private network connections that you want to be part of the bridge.
3.Right-click one of the highlighted private network connections and click Bridge Connections.
