Description Windows Server is Microsoft's solution for workgroup file, print, and communication servers, as well as for Internet content delivery. If an organization has a large number of authenticated external Internet users accessing Windows Server or utilizing Windows Services, an external connector license (ECL) allows an unlimited number of simultaneous connections. This offer provides one ECL for Windows Server. For a small number of authenticated external users, a more economical solution might be to acquire client access licenses (CALs) for the maximum number of simultaneous connections expected. Please note that an organization with an ECL still has to acquire CALs for the internal devices accessing the server. No license is required for anonymous Internet users. 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.
