Remote Desktop Licensing (RD Licensing)
Remote Desktop Licensing (RD Licensing), formerly Terminal Services Licensing (TS Licensing), manages the Remote Desktop Services client access licenses (RDS CALs) that are required for each device or user to connect to a Remote Desktop Session Host (RD Session Host) server. You use RD Licensing to install, issue, and track the availability of RD CALs on a Remote Desktop license server.
For more information about RD Licensing, see the Remote Desktop Services page on the Windows Server 2008 R2 TechCenter (
The following topics are covered:
In Windows Server 2008 R2, a terminal server is now called an RD Session Host server. Also, Terminal Services client access licenses (TS CALs) are now called Remote Desktop Services client access licenses (RDS CALs). In these Help topics, these new terms are used, even when referring to previous versions of Windows Server. Note that security group names have not changed in Windows Server 2008 R2.
