Tom, Do you mean the Socks filter under Extensions - Application filters. I was thinking of blocking the 1080 port. What do you think ?

It worked fine. What about the MSN Messenger. I blocked it on the ISA but when I play around in the connections TAB and I check I use proxy then I choose Socks and in the IP address I add the loop back address, it works fine !!!!!!! Any suggestions ?? Thanks again.

The problem with Yahoo Messenger is once you block port 5050 Outbound, it will keep trying other ports which will also slow down your network. Here you go... 1. In ISA MMC, browse thru Policy Elements - Destinationset- Create New Set- Deny Yahoo- ADD- A) shttp.msg.yahoo.com B) shttp.msg.yahoo.com/notify C) insider.msg.yahoo.com D) update.messenger.yahoo.com E) us.dl1.yimg.com F) us.update.companion.yahoo.com G) ypager.exe (IMPORTANT) H) yupdater.exe (IMPORTANT) 2. Now, browse thru Accesspolicy-Site&ContentRule-NewRule-Deny Yahoo-Deny-Custom-Specified Destinationset-Deny Yahoo to any request You are done, You may want to restart isactrl, and try to login to your Yahoo Messenger. This shuld work...! Good Luck.!

How can I block Yahoo Messenger for Web Proxy clients. I created a protocol rule and I blocked the TCP 5050 for inbound and outbound but still the users can access Yahoo messenger. Please advice.
