Many Thanks. 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.
Ahmed

Salaam Nabil,
I know itz very annoying, but don't worry, here are few steps which you need to
follow. 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.!

Good morning All,
This is very annoying issue. 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.
Thanks,
Ahmed

Is there a way to configure so as to have the message screener scan outbound as
well as inbound?
