Windows Server: An Overview of Remote Desktop Services Licensing
Summary: This article provides information about licensing for the Remote Desktop Services role in Windows Server.
Instructions
Remote Desktop Services has three licensing modes:
- Remote Desktop for Administration: This licensing mode allows for up to two administrative sessions, including the local console session, to run simultaneously on a Windows server. This is the only licensing mode that does not require Remote Desktop client access licenses (RD CALs) or a license server. It is intended to allow administrators to connect to a Windows server remotely in order to perform administrative tasks. A server is in Remote Desktop for Administration licensing mode if the Remote Desktop Session Host role service is not installed.
- Per User: This licensing mode requires an RD CAL for each unique user that connects to a Remote Desktop Session Host server. This is true regardless of the number of devices from which that user connects.
- Per Device: This licensing mode requires an RD CAL for each unique device that connects to a Remote Desktop Session Host server. This is true regardless of the number of users that connect from that device.
Per User and Per Device licensing modes require that a server in the environment be configured with the Remote Desktop Licensing role service. RD CALs must be purchased and installed on the license server.
There are two types of RD CALs, corresponding to the two license modes that require them. A Remote Desktop deployment must use one license mode or the other. A license server can support multiple deployments and can have both types of CALs installed simultaneously.
RD CALs are installed using the Remote Desktop Licensing Manager console. The same console can be used to convert RD CALs from one type to the other. For information on installing and converting RD CALs, see How to Install and Convert Windows Remote Desktop Client Access Licenses.
