Windows Server 2008 - 20 User CALs through the Microsoft Open Business Program
This product comes pre-bundled with 20 CALs. If you need additional CALs you may order them seperately.
Windows Server 2008 builds on the success and strengths of its Windows Server predecessors while delivering valuable new functionality and powerful improvements to the base operating system. New Web tools virtualization technologies security enhancements and management utilities help save time reduce costs and provide a solid foundation for your information technology (IT) infrastructure. A Windows Server User CAL permits one user (using any device) to access or use the server software. User CALs are likely to be more cost effective than Device CALs if there are multiple devices per user (for example a user has a laptop and handheld computer accessing Windows Server)
A Server License is required for each operating system environment running Windows Server. A User/Device CAL is required when a user or device is directly or indirectly accessing a Windows server. Additionally if the user or device is accessing or using the terminal services functionality of Windows Server a TS CAL is also required. This product comes pre-bundled with 20 CALs. You can order additional CALs if needed.
