Ask AOL, Yahoo, etc. Or just check the preferences tab. They have that information available to the user (and available to be changed). And the standard port for AOL IM is 5190. Justin C.

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. Angie Wawrzaszek M.I.S.
