in general it would be easier to make the clients limited users and only allow Administrators to run the P2P programs.
Using Software Restriction Policies to Block Spyware-Adware
 open the run cmd> gpedit.msc,  go Computer Configuration > Windows Settings > Security Settings > Software Restrictions
You can set it up to disable software from running by a number of different factors.

You could  use spybot S&D  tea timer

Setup a firewall and simply block the ports the programs use.  Make sure the firewall is password-protected so they can't get in and open the ports again.  They can install and run the program, but it simply won't connect
Use ZoneAlarm if you want an all in one solution (Firewall, Antivirus, Antispyware, Parental Filter, ID Blocker (Prevents things like credit card numbers being used over the internet).,

add the P2P to the hosts file
block the ports in your cable / dsl router
Another i have seen here on EE is limit the internet access coud stop them in thier tracks.

Hello there,

I recommend using ISA Server from Microsoft. I think it is one of the best softwares to manage your network.

Take a look here:

Good luck.
You can try disabling UDP on your firewall. This will disable ping into machines on your network. Do you have a hardware firewall (please say yes)? If you do this should be easy to configure on it. Ping is relied upon by most P2P software.
