What is RDS, and why are CALs required?

What RDS does

RDS provides remote access to Windows Server desktops, applications and shared work environments. In older releases the same role was called Terminal Services.

Why CALs are needed

Every user or device that connects to Remote Desktop Services needs an RDS CAL matching that Windows Server version.

How CALs are managed

CALs are installed and tracked through the Remote Desktop Licensing role in Windows Server.

What a CAL is not

An RDS CAL does not include the Windows Server operating system, application licenses, hosting or server setup.

Will these RDS CALs work on my server?

Yes, as long as it runs a supported Windows Server with Remote Desktop Services turned on. It does not matter where the server runs.
