I am not 100% sure, but I would think they would both just need to be on the same workgroup. To do that, goto System Properties in Control Panel (Or windows-break for short), and then go to the "Computer Name" tab. Then just click on the Network ID button and follow the step by step instructions. Another thing that may cause your computers not to see each other is the actual cable. Make sure it is a cross over cable, thats the only real concern with the cable (that and its not frayed beyond all recognition). Hope this helps a little bit.
