About This Item

A Windows Server 2019 Remote Desktop Services (RDS) CAL allows users to unlock the full range of Remote Desktop Services features within Windows Server 2019.
This CAL is purchased in addition to standard Windows Server CALs and enables session-based desktops, Virtual Desktop Infrastructure (VDI), and remote access to applications from anywhere with an internet connection.

Description

Windows Server 2019 RDS CALs provide users with the ability to access desktops, applications, and Windows features remotely and securely. By adding an RDS User or Device CAL to your existing Windows Server installation, you gain access to a powerful desktop and application virtualization platform.

RDS allows users to:

• Connect to virtual desktops

• Access applications hosted on the server

• Work securely from any location

• Use Windows features via a reliable, internet-connected environment

This makes RDS an essential component for organizations that rely on remote work, virtualized workloads, or centralized application delivery.

Safe & Reliable Remote Work

Windows Server 2019 includes multi-layered security to protect your environment from modern digital threats. With built-in intrusion prevention, Windows Defender, encryption services, and powerful administrative tools, users benefit from:

• Strong protection against attacks

• Secure remote access

• Reliable and encrypted workflows

• Continuous monitoring and threat detection

Whether users are working remotely or on-site, Windows Server 2019 ensures a secure and dependable experience.

Licensing Requirements

Remote Desktop Services is a core component of Windows Server 2019.
To use RDS features, the following are required:

1. Windows Server 2019 License

A valid license for each installed copy of the server software.

2. Windows Server 2019 CAL

Per User or Per Device CAL for general server access.

3. Windows Server 2019 RDS / Terminal Server CAL

Per User or Per Device CAL for remote desktop and virtual session access.

A Windows session is any session where the server hosts a graphical interface on a device.

User CAL vs Device CAL

RDS User CAL

Allows one user to access the server from any number of devices.

RDS Device CAL

Allows one device (used by any user) to access Windows Server sessions.

Both CAL types can coexist in your environment and can be managed by the license server simultaneously.

Technical Licensing Notes

• In Terminal Services Configuration → Server Settings → Licensing, you can choose Per User or Per Device mode.

• Windows sessions are not permitted in Pro Server mode.

• You do not need an RDP CAL when connecting to the console session, which refers to the physical primary keyboard and display of the server.
