Hello,
Thank you for posting in the Microsoft community forum.
By default, Windows Server 2022 Standard supports only two concurrent RDP connections. To allow all six users to use the Remote Desktop Services on Windows Server 2022 Standard Edition at the same time, you need to install the RDS role, configure the license server, and purchase the Remote Desktop Services Client Access License (RDS CALs).
The following article will help you understand how to deploy a remote desktop environment:
