Windows CAL

Question

Hi Microsoft Team,

I'm planning to purchase a Windows CALS for my Windows server 20212 R2 but, I don't have an idea and still confuse about RDS user CALS and User CALS.

It will be helpful for me if you can elaborate more and explained the things that I need.

I do appreciate your quick response.

Thank you!

Hello @jomark bancale

A Windows Server CAL gives a user the right to access the services of the server.

CALs are used in conjunction with Microsoft Windows Server OS licenses to allow Users and/or Devices to access and utilize the services of that server OS:

• User CALs allow a single user access to Windows Server from an unlimited number of devices
• Device CALs allow an unlimited number of users to access Windows Server from a single device

Windows Server Client Access Licenses

When comes to RDS CAL, it is different than CALs stated above but required for users or devices that want to utilize Remote Desktop Service functionality on Windows Server, which also consists of types of Per Device and Per User.

RDS Client Access Licenses

Keep me posted how it goes. Thank you and have a great day!
