Microsoft R18-02907 Windows Server 2008 CAL 5 Users

The Microsoft Windows Server 2008 CAL (Client Access License) 5-pack provides user-based access licenses that authorize up to five named users to connect to services running on a Windows Server 2008 installation. In Microsoft's licensing model, every user or device that accesses a Windows Server requires a corresponding CAL, making these licenses a compliance necessity rather than a feature-rich product. This particular pack uses user-based licensing, meaning each license is tied to an individual person who can then access the server from any number of devices — a practical choice for workers who switch between desktops, laptops, and mobile devices.

It is important to understand the limitations of this product. These CALs are version-specific to Windows Server 2008 and cannot be used to access newer server editions. Furthermore, Windows Server 2008 reached its end of extended support in January 2020, meaning the platform itself no longer receives security updates through standard channels. Organizations purchasing these CALs are typically maintaining legacy systems that have not yet been migrated and need to remain compliant in the interim. For any new deployments, current-version CALs and server software should be considered instead.
