Description Windows Server is Microsoft's solution for workgroup file, print, and communication servers, as well as for Internet content delivery. A device client access license (CAL) is needed for every device accessing Windows Server for file services, printing services, remote access service, or terminal services. It is also needed for any authenticated devices accessing Windows Server as a web server or an application server. This offer provides one device CAL that authorizes one computer to access Windows Server, regardless of the number of users (for example, on a shared workstation). User CALs for licensing individuals and external connector licenses (ECLs) for licensing a significant number of external users are also available. Additional Information For additional information about the available editions of Windows Server and the server and client licensing requirements, see the Guide to Windows Server Editions and Licensing.
