Terminal server licensing is a feature of Windows Server that allows you to provide remote access to desktops and applications hosted on a server. Terminal server licensing requires two types of licenses: a Windows Server license and a Remote Desktop Services client access license (RDS CAL). In this article, we will explain how terminal server licensing works in Windows 10 and how to install and manage RDS CALs.
Windows 10 supports two modes of remote access: Remote Desktop and RemoteApp. Remote Desktop allows you to connect to a full desktop session on a remote server, while RemoteApp allows you to run individual applications hosted on a remote server. Both modes require a Windows Server license and an RDS CAL for each user or device that connects to the server.
There are two types of RDS CALs: per device and per user. Per device RDS CALs are assigned to each device that connects to the server, while per user RDS CALs are assigned to each user in Active Directory. Per device RDS CALs are tracked by the license server, while per user RDS CALs are not enforced by the license server, but by the administrator's responsibility. Per device RDS CALs can be revoked up to 20% of the total number of licenses, while per user RDS CALs cannot be revoked.
When you use the per device mode, a temporary license is issued the first time a device connects to the server. The second time that device connects, as long as the license server is activated and there are available RDS CALs, the license server issues a permanent RDS CAL. When you use the per user mode, each user is granted a license to connect to the server from any number of devices. The license server issues licenses from the available RDS CAL pool or the over-used RDS CAL pool.
To install and manage RDS CALs, you need to install and activate a Remote Desktop license server on your network. You can use the same server that hosts the Remote Desktop Session Host role or a separate server. You also need to purchase RDS CALs from a Microsoft partner or reseller and enter them into the license server.

Terminal server licensing is a feature of Windows Server that allows you to provide remote access to desktops and applications hosted on a server. Terminal server licensing requires two types of licenses: a Windows Server license and an RDS CAL. You can choose between per device and per user RDS CALs depending on your needs. You need to install and activate a Remote Desktop license server on your network and enter the RDS CALs that you purchased into the license server. You can also manage and monitor the RDS CAL usage on the license server.
