Source:  NDPS, Broker NLM program

Explanation:   An application requested the Broker to enable a service that is already enabled or to disable an unknown service.

Possible Cause:  The application you are running encountered a programming error.

Action:  The application should ensure that the service is currently disabled before sending the Broker's request to enable that service.
