What is RDS and why are RDS CALs required?

Remote Desktop Services lets users connect to Windows Server; a CAL licenses each user or device.

What RDS does

RDS lets businesses provide remote access to Windows Server desktops, applications and shared work environments. In older Windows Server environments, this remote access was commonly called Terminal Services.

Why CALs are needed

When users or devices connect to Remote Desktop Services, they need the correct Microsoft RDS CALs for that Windows Server RDS environment.

How CALs are managed

In a standard RDS deployment, RDS CALs are installed and managed through the Remote Desktop Licensing role in Windows Server.

Choose whether access follows a user or a device

User CALs when access follows people; Device CALs when it follows shared machines.

RDS User CALs

Best when the same named users need Remote Desktop access from more than one device. User CALs require Active Directory.
Best when
  • Named users connect from different devices
  • Access is tied to employees or regular users
  • The environment uses Active Directory

RDS Device CALs

Best when access is tied to the machine rather than the person. Works with or without Active Directory.
Best when
  • Multiple people use the same workstation
  • Access is tied to fixed devices or terminals
  • The server is in a Workgroup environment

No. Our RDS CALs are approved for worldwide deployment and are not region-restricted. You can install and deploy these licenses on servers located anywhere in the world.
Can I use these RDS CALs on cloud servers?
