I would change the listening port for the Blackberry component if possible, because changing the listening port for the McAfee Agent will impact all your clients.
To check if it's really the blackberry component that's causing issue you can run "NETSTAT -AB" and verify if port 8081 is in use, and which process opened the port.
This sound like another language. Please, translate to English!
It's German. He has an error in the agentlog that port 8081 cannot be opened, on a server that's running some blackberry software that uses this same port.
@mischaboender: thanks for your reply and the translation. i am gonna suggest to change the blackberry port.
@fichaelmigg: sorry for the confusion. next time i am going to write in english from the start. ;-)
