Source: NetWare GroupWise Message Transfer Agent.
Explanation: The MTA cannot start because the agent engine (gwenn4.nlm) is not compatible with the MTA itself (gwmta.nlm).
Possible Cause: Some agent files have been updated but the update is not complete.
Action: When updating the agents, make sure all agent files are installed. For a complete list of files, see "Agent Installation Directories" in GroupWise 6.5 Troubleshooting 3: Message Flow and Directory Structure.
Possible Cause: The agent engine (gwenn4.nlm) was not unloaded prior to updating the agent software. The agent software cannot be successfully updated if the agent engine is still loaded.
Action: After exiting all the agents, unload the gwenn4.nlm, then perform the update. See the "Updating Secondary Domains" in "Updating Your GroupWise 6.x System to Version 6.5" in the GroupWise 6.5 Installation Guide.
