Just run the network setup wizard on one pc, when it asks if you want to make a floppy at the end, say yes. Run that floppy in pc no 2 and that should set your basic network up between the two pcs.
Make sure that both pcs have the same workgroup name, usually MSHOME.
You will then need to go to each folder that you want to share with the other pc and right click and select SHARING and Security. In that part tick Share this folder on the network and Allow network users to change my files. The second one should allow one pc to send to the other, if thats not ticked you can only drag from one pc to the other
