RESOLUTION
=============
If the service is running in an ActiveMatrix Node then you do not need to create a proxy to an end point to manage it. You can directly create policies on the end point.

To be able to create a proxy to an end point that is running in ActiveMatrix Node you need to have Policy Agent installed and an instance of Policy Agent configured to work with Policy Manager.
