Home network

I am trying to set up a home network using 2 pcs running XP pro. One, the host has a DLink PCI 10/100 card and the over has an Intel m/board (8020) with on board ethernet. I am using a cat 5 cable. I ran network set up wizard from both computers and everything seems to be working but I can’t ping either computer from the other or see them in network places. Any suggestions where I am going wrong
