RE: Off topic ... blocking chat programs
Well you almost got it but you have to be a little more tenacious to really block it effectively. On AIM you have to block every port going to those addresses. In the AOL IM setup you can change the port number to 80 for example and connect to the servers. Then you have to take into account that users can go to http://www.aol.com/aimexpress/ <http://www.aol.com/aimexpress/> and use the web client. So, depending on how strict you get you might have to block access to all of the www.aol.com <http://www.aol.com> IP's. So, basically... it's a losing battle to say the least. I would recommend getting management to do their job and proactively enforce policies... rather than trying to block access to the wide gamut of chat clients.
