I think we’ll need some more detail.
When you enroll in MCM, you can have two distinct types of devices for each endpoint - the ‘native agent’ which is the BESClient service running in the endpoints native OS, and the “MCM Agent” which is the MCM functionality. These two endpoints can be represented in a single “correlated” computer object but still operate independently.
When you send an Action, you might be sending an “MCM action” (like ‘Wipe Disk’ or 'Lock Device) that is targeted & processed to the MCM agent, or a “native action” (like “install a patch”) that is targeted & processed by the native agent.
So, first - do you have both the ‘native agent’ and ‘mcm device’ agent for these endpoints? And what kind of Action are you sending?
