Well, once you create the filter, you can look at your access logs to see what has been 'denied' you would see the source address and using good ol troubleshooting tools, etc you could find out which computer/user is using it!
Just one way in which to skin this particular cat! Another option, is don't give users administrator rights to their machines. Removing this right, stops them from installing the clients, be it MSN, Yahoo, etc? Obviously only works if you your are running WinNT, 2K or XP Manish -----Original Message----- From: Mr piyush shah [mailto:parag_ch2000@;yahoo.co.in] Sent: 31 October 2002 11:17 To: [EMAIL PROTECTED] Subject: Fwd: RE: Yahoo messanger traffic can be seen/blocked?
