I have followed the instructions on IM Filtering outlined in www.isaserver.org/pages/article_p.asp?id=1247
But I can not get Yahoo IM 6.0 blocked.
I have tried the Http filtering for the signature. I have tried blocking the domains for Yahoo IM. I am fresh out of ideas, and my boss wants this blocked ASAP. Any help would be wonderful.

Thanks

Hi Michael,

Check the log files on the ISA firewall and see what is being allowed through, then disallow it.

HTH,
Tom

I think I have found a way to block it, but yahoo IM is very trickey.
It will go over http or telnet in order to get out. It will also do a random port scan to get out. This makes it almost impossible to block it. I have a few ideas I am trying out. I will let you know if I get anywhere.
