Hi All, I'm trying to find a free program that scans the PC for any P2P software and removes it. Anyone know of a good reliable program for this? Or some way of working out which PC an my LAN is downloading/uploading my ISP is telling me somthing is downloading at 154kb but I don't know which PC it is??? Please Help!!

Hi Matt, if you want to stop people from using P2P software at work - block all ports except 80, 8080, 3389, 25 and 110
These are the general office ports - such as http, RDP, smtp and pop3

Thank you GaRHaR for some reson I new it would be you that answered this one "GaRHaR the top gun!!" I will do it now and see how it goes I will post back here shortly
Thanks Mate

Lol, it's because i'm at work and have to deal with this sort of poo for 25 seperate networks

GaRHaR I endup assiging all internet pc's with a static ip address and only letting the specified ip range out through the router which seems to have disconected the rouge computers access. With blocking of the ports as you mentioned is there an easy way of donig this at the router or duz it have to be done to each PC? My router is a BESFX41 linksys all the PC's are XP pro.

easiest way to block specific ports for the whole network - is to close the router completely. Don't let anything through.

Then forward any port 3389 request through to the domain controller or gateway machine

And open ports 8080, 80, 25 and 110 - this will give you enough functionality that only people doing naughty stuff will be caught.

And you can then setup etheral to monitor those ports specifically and when you're getting reduced internet speed - bang...find the ip...and do what you want with it.

Thankyou for the excellent advice it has been very usefull .
