The mechanism that governs this access is the Remote Desktop Services Client Access License (RDS CAL). There are two primary types of RDS CALs available, and choosing between them requires a strategic analysis of the organization's workforce. The first is the Device CAL, which licenses a specific physical device to access the server. This model is cost-effective for organizations where multiple employees share the same workstation, such as in a call center or a manufacturing environment with shared kiosks. The second type is the User CAL, which licenses a specific individual to access the server from any device. In modern, mobile-first workplaces where employees might connect from a laptop at home, a tablet on the road, or a desktop in the office, User CALs are generally the preferred and more practical choice. It is important to note that these RDS CALs are additive; they are required in addition to the standard Windows Server CALs, effectively doubling the licensing investment for remote access. remote desktop server license
Best for: Modern offices with remote or mobile workers who use multiple devices.
