What Is a Device CAL for Windows Server 2019 RDS?

Windows Server 2019 is a robust and feature-rich operating system designed for business-critical environments. However, to use all its features and enable remote access via Remote Desktop Services (RDS), Client Access Licenses (CALs) are required. A Device CAL allows one specific device to connect to your Windows Server infrastructure, regardless of who is using it. This makes it ideal for workplaces where multiple users share the same workstation or terminal.

• Access server-based applications
• Connect to session-based or virtual machine (VM) desktops
• Utilize RDS for secure remote server access

Once assigned, a Device CAL permanently licenses that device, allowing any number of users to access the Windows Server environment without additional user-based licensing. This makes it perfect for shared computers or shift-based environments.

Device CAL vs. User CAL – Which Is Best for Your Organization?

When choosing between Device CALs and User CALs, the decision depends primarily on how your organization’s users access the network and server resources.

License Type	Best For
Device CAL	Ideal for organizations where multiple employees share one workstation — such as in shift work, manufacturing, or point-of-sale environments.
User CAL	Best for users who need access from multiple devices and locations, providing maximum flexibility for mobile or remote workers.

Both CAL types grant access to the same Windows Server features. Choosing the right type ensures cost efficiency and compliance according to your organization’s usage patterns.
