You need a cross over cable (unless the LAN ports on the PCs autodetect MDI/MDX). Autodetect ports are typically only on newer switches. If you connect the two PCs, does a light come on (typically an orange or green light right next to the cable plug).
You can't use a cable like that without a switch or hub. Hub/switches have the TX and RX on the ports reversed.
If you go PC to PC that will just be TX to TX and RX to RX which will not work. You need a cross over cable, so TX goes to RX and RX goes to TX.
