Easiest way is to use Windows Update to find/install all the drivers you need. Just need to get the network driver. Easiest way to do that is to install a USB network adapter that has a known winXP driver that you can instal from disk. The usb adapter needs to be in the laptop just long enough to run windows update, that will get the built in network adapter running.
(Each device identifies itself. Windows recognizes and provides driver. If windows doesn't have driver then you are out of luck. The fact that windows installed says windows found all of the important parts)
