To resolve this issue, you can either disable the policy setting (Method A), or edit the permissions to provide the Licensing Service the required permissions (Method B).

  1. I can only click on the properties (popup menu) of the service name “Plug and Play”. It is not possible to disable it although the permission is set to “Not Defined”. There is no “Edit Security” button or “Advanced” button. In the properties window there is only the button “View Security” that is disabled. Could you help me, please?
