Please don't forget to mark your thread solved with whatever answer helped you : ) Rafeeq
Accept that application device control policy is effective, but i cannot block it according to particular time, say after office hours i cannot enable them back, so i am looking at firewall rules.
Move the rule to the top and see if that helps.

Still it remains the same.
Hi
IPS policy is the better way for blocking yahoo messenger. to do that please follow the instruction:
in the policies menu> Intrusion Prevention> Add an intrusion prevention Policy> enter a name for policy and then go to exceptions menu> Click on Add button> Find "Yahoo IM Login" and select it> Click next and select Block as action. then save the policy and assign it to the group.
Why may I ask do you want to disable messenger during work hours, instead of at all times?
Hello there,
The easiest way to do this using Firewall rule is as below:
1. Create a Blank Rule and name it as Block Yahoo
2. Double click on Host List (where Local/Remote option box is checked)
3. Under "Remote hosts that apply to the firewall rule:" click Add button
4. From "Type" dropdown list select "DNS domain"
5. Under "DNS Domain" test field type as below:
*.yahoo.com
6. Click OK and then click OK again
7. From the "Action" set it to Block
(You can also set the logging to traffic log so that you can check if the Firewall Blocked it)
8. Assign the policy to the desired Group.
Note: Your clients wouldn't be able to browse www.yahoo.com as well. But there is many other ways you can do it.
Should be all good.
