Hello there,
If you have 50 Client Access Licenses (CALs) for Remote Desktop Services (RDS), it should allow you to have 50 simultaneous RDS sessions, not just 25. Each CAL grants one user or device the right to connect to the RDS environment.
If you are experiencing a limitation of only 25 simultaneous RDS sessions, there could be several reasons for this:
License Configuration Issue: Double-check your RDS license configuration to ensure that all 50 CALs are properly installed and activated on the license server.
License Expiry: Confirm that the CALs you have are still valid and have not expired. CALs typically have an expiration date, and you need to renew them before the expiration.
Per User vs. Per Device CALs: Verify whether you have "Per User" or "Per Device" CALs. "Per User" CALs allow a user to connect to the RDS environment from any device, while "Per Device" CALs allow any user on a specific device to connect. If you have "Per Device" CALs and multiple users share the same device, it might lead to a limitation of simultaneous connections.
Connection Limit on the RDS Host: Check if there is a connection limit configured on the RDS host. Some versions of Windows Server have default connection limits that need to be adjusted manually.
