Source: NDPS, Notification Service NLM program
Explanation: The ENS could not find the NLM program that implements one of the delivery methods.
Possible Cause: An NLM program that implements a delivery method did not exist in the system directory of the server.
Action: Make sure that the all NLM programs that implement all delivery methods (files with the .enm extension) reside in the system directory of the server.
