After MOM failed over successfully, EM Service (Windows service) will not start.
EMService log has no ERRORs but exception:

The Account assigned for EM Service does not have access to the Shared drive used for APM High Availability.
Seems like the user logged into launch the EMService (local account) does not have access /permission to the NAS drive.
