Symantec Endpoint Protection Manager (SEPM) offers an option to use Host Groups.
SEPM 14 RU1 MP1 does not allow deleting of Host Groups despite not being used. The following error is observed when trying to delete unused Host Group:
"The host group can not be deleted because it has been applied to the location "XXXXX" in the group "My Company\XXXXX"
The local policy reference in a group location was not removed when the location no longer applied the local policy, and the unused local policies still exist in SEPM database.
The problem has been fixed in Symantec Endpoint Protection Manager version 14.2.
