This policy setting allows you to specify the type of Remote Desktop Services client access license (RDS CAL) that is required to connect to this RD Session Host server.

You can use this policy setting to select one of two licensing modes: Per User or Per Device.

Per User licensing mode requires that each user account connecting to this RD Session Host server have an RDS Per User CAL.

Per Device licensing mode requires that each device connecting to this RD Session Host server have an RDS Per Device CAL.

If you enable this policy setting, the licensing mode that you specify takes precedence over the licensing mode that is specified during the installation of Remote Desktop Session Host or specified in the Remote Desktop Session Host Configuration tool.

If you disable or do not configure this policy setting, the licensing mode that is specified during the installation of Remote Desktop Session Host role service or specified in the Remote Desktop Session Host Configuration tool is used.
