Answer 2

Hi,
Thank you for posting your query. According to your description, here are some hints for you.

A Windows Server CAL is a license that allows customers to access Windows 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

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.
