What Is a User CAL for Windows Server 2019 RDS?

Organizations running Windows Server 2019 require Client Access Licenses (CALs) to fully unlock the system’s capabilities. A User CAL grants one individual user the rights to remotely connect to the server and access its services from any compatible device.

• Use RDS services for secure remote access to the server
• Connect to session-based or VM-based desktops
• Access server-based applications from any location

A User CAL is required for each individual user who needs remote access to the server environment. It’s ideal for employees who frequently connect from multiple devices or locations. For organizations with more devices than users, User CALs also offer significant cost efficiency by simplifying license management and reducing administrative overhead.

User CAL vs. Device CAL – What’s the Difference?

Choosing the right CAL type is essential for maximizing value and minimizing costs. The main distinction lies in what entity — user or device — the license covers.

• User CAL: Best for employees who use multiple devices (PCs, laptops, tablets, or smartphones) to access the server from different locations.
• Device CAL: Ideal for environments where several users share the same physical device, such as in shift work or hot-desk setups.

Both license types grant access to the same Windows Server features — the choice depends on how your organization operates. Selecting the correct model ensures compliance and the most efficient use of your IT budget.
