I finally solved it, I am now blocking the Instant Messenger through the Cisco Router. I got all the IP addresses that it tried to access (through my packet sniffer) and I entered them into my extended ip access list.<br>I read everything I could on the subject today and gave myself a lesson in Router 101. If you would like the list I made, you can email me at <A HREF="mailto:jjasper@world.std.com">jjasper@world.std.com</A>
