I also have to deal with users trying to run P2P programs or IM applications on my network all the time. Other than running anti-virus software or spyware applications on each system, I would recommned deploying an IPS appliance on the network in a few places to anaylze the traffic that traverses the network. I have a few these on my network and they catch P2P traffic all the time, in addition to providing information on the source and destination address, hostname, ports, etc.

You may need to install the program to find out what port is uses. Once you know what port is uses, you can block it.

If you are running group policy you can use software restrictions to block the programs. Here is a link to a microsoft article about doing it.
