Windows Server and CAL Licences

If you want to learn more about what CAL's are and why Microsoft requires them for each user and device that accesses the Windows Server, keep reading.

What are CAL’s and why are they needed?

CAL’s, as briefly described above, are Client Access Licences. These licences allow the user to access the Windows Server and its functions, whether it's the database, mail servers, Power Automate, etc.

There are 4 types of CAL; The User CAL, the Device CAL, the RDS User CAL (RDS=Remote Desktop Service) and the RDS Device CAL.

User CAL (User CAL)

This licence allows a user to access the server, regardless of the device they are connecting to the server with. A User CAL is a licence for a single user.

For companies where users need to access the server from various devices, such as desktop computers, laptops and mobile phones, this type of CAL is ideal to avoid having to buy multiple CAL’s for a single user.

Device CAL (Device CAL)

The Device CAL licence, on the other hand, applies to a single device, regardless of the number of users who use that device to access the server.

This type of CAL is most suitable for companies where numerous users share a single device, such as a kiosk or a shared computer.
