It would seem to me that if you monitored your OUTGOING ports, that should solve the problem. If AIM uses port 5190 (the setting in my program) it would seem to be a simple matter to stop outgoing traffic thru that port. But then, there are 64K other ports to choose from...

Subject: blocking ports

The instant messengers that come with many browsers like AOL create a security problem. We would like to block the use of instant messengers by blocking the port through TCP/IP that they come in on. Does anyone know how to determine what port these messengers use? Or any other way to prevent use of these. Monitoring that no one installs one on their PC would be a nightmare, and a full time job.
