A CAL is needed for every device or user accessing the server for using file services, printing services, remote access service, or terminal services, or any authenticated users accessing Windows Server as a Web server or an application server. For a significant number of authenticated Internet users, an external connector license is available.
This user CAL authorizes a user to access Windows Server from any device (for example, when an employee accesses the server from a computer at work and another at home). Device CALs are also available. A device CAL authorizes one computer to access Windows Server, regardless of the number of users (for example, on a shared workstation).
Under the Software Assurance Programme, customers acquire the right to install any new release of products covered in the agreement during the term of their coverage.
