We send alerts from our App manager server to our supervision console by using the action “SNMP trap Action”. Normally the action works without any problem, but recently it has stopped working. When I execute the action manually by clicking on the button "Execute", I get the message “Action Failed” see screenshots included.

Build number = 8602

Operating System = Windows 2003, 5.2  

I have tested the port snmp (162) & there is no problem.
