Dude you are faast! Follow the same procedure for MSN too.. Like you need to
identify which file it uses to connect to proxy, may be "msmsgs" and you may
need to do the same steps and create destination set for that.

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?
