Set the Remote Desktop licensing mode

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 Remote Desktop licensing mode that you specify is honored by the Remote Desktop license server. If you disable or do not configure this policy setting the licensing mode is not specified at the Group Policy level.
