Windows Server – User CALs

A Client Access License (CAL) is required to legally access the functions and resources of Windows Server. There are two types of CALs: User CALs and Device CALs, each suited for different business needs. Choosing the right license ensures that companies both comply with licensing terms and optimize costs and efficiency.

A User CAL is assigned to a specific user, allowing that user to access the server from various devices such as a desktop, laptop, or tablet. This type of license is ideal for companies where employees work with multiple devices. A Device CAL, on the other hand, is assigned to a specific device, allowing any user who uses that device to access the server. This is particularly advantageous in call centers, libraries, or shared workspaces where multiple users use the same device.

The decision between a User CAL and a Device CAL depends on how server access is organized within a company. User CALs are better suited for employees with multiple devices, while Device CALs are a cost-effective solution for workspaces with shared computers. The right choice helps businesses ensure license compliance, control costs, and optimally design server access.
