Hello
Thank you for your question and reaching out. I can understand you are having query related to RDS Licensing.
A license that grants users access to Windows Server is known as a Windows Server CAL. To enable Users and/or Devices to access and use the services of that server OS, CALs are used in conjunction with Microsoft Windows Server OS licenses:
• A single user may access Windows Server from an infinite number of devices thanks to user CALs.
• Windows Server can be accessed by an unlimited number of users from a single device thanks to device CALs.
RDS CALs, which also exist in Per Device and Per User varieties and are distinct from the CALs mentioned above, are necessary for users or devices who wish to access the Remote Desktop Service feature on Windows Server.
