Description Windows Server is Microsoft's solution for workgroup file, print, and communication servers, as well as for Internet content delivery. A user client access license (CAL) is needed for every user accessing Windows Server for file services, printing services, remote access service, or terminal services. It is also needed for any authenticated users accessing Windows Server as a web server or an application server. This offer provides one user CAL that 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 for licensing computers 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. License OnlyThis license does not require media, license keys, or setup codes.CALs, ECLs, and management licenses (MLs) offered through TechSoup are always for the currently offered version of the server software. However, these licenses can also be used with earlier versions of the server software.Microsoft Requires a Certificate of Eligibility for Discounted ProductsTo receive discounted Microsoft products, you must first register at Microsoft's nonprofit portal.
