What is a Client Access License (CAL)?

A CAL is a license that allows a user or device to access resources on a server. There are two main types of CALs:

  • User CAL: Allows one user to access resources on the server, regardless of the device they are using.
  • Device CAL: Allows one device to access resources on the server, regardless of the user who is using the device.

What is Microsoft Windows Server 2016 5 Device CAL?

Microsoft Windows Server 2016 5 Device CAL is a device CAL that allows five individual devices to access resources on a Windows Server 2016 Standard or Datacenter edition server. This license type is ideal for organizations with multiple devices that need to access resources on the server, such as:

  • Laptops: Employees can use their laptops to access files, folders, printers, and other resources on the server.
  • Desktops: Desktops in the office can be used to access resources on the server.
  • Virtual machines: Virtual machines hosted on the Windows Server can use this CAL to access resources on the physical server.

Benefits of using Microsoft Windows Server 2016 5 Device CALs:

  • Increased flexibility: Users can access organizational resources from any authorized device, regardless of their location.
  • Improved management: Device CALs make it easy to track and manage which devices have access to the server.
  • Reduced costs: Compared to purchasing user CALs for each device, using device CALs can save money for organizations with many devices used by different users.

Important notes:

  • You need a Windows Server 2016 license to use CALs.
  • You need a CAL for each user or device that accesses the server.

Microsoft does not currently offer direct downloads for CALs. A Microsoft Authorized Reseller will provide you with the license and activation instructions after purchase.
