A Client Access License ("CAL") is a kind of software license distributed by Microsoft to allow clients to connect to its server software and use the software's services.
A Client Access License (CAL) is a kind of software license that legally permits client computers to connect to Microsoft server software. They usually come in the form of a Certificate of Authenticity (CoA) and a license key, which is sometimes attached to the certificate itself. The various editions of most of Microsoft's server software usually include a small number of CALs, and this allows the software to be used by either a few users or a few computers, depending on the CAL licensing mode. If more connections to the server are needed, then additional CALs must be purchased.
Microsoft offers flexible, cost-effective options for licensing the Windows Server 2003 family of products, including Windows Server 2003 R2 editions. Similar to previous Windows Server licensing models, one server license is required for each copy of the server software installed. In addition, a Windows Server 2003 Client Access License (CAL) is required for each user or device (or combination of both) that accesses or uses the server software. The same Windows Server 2003 Client Access License is used to access both Windows Server 2003 and Windows Server 2003 R2 servers.
