RDP more than two Simultaneous Access Limitations to Windows 2016 Server

I have stood up a VM Windows 2016 server which hosts an application multiple users need to access simultaneous. Currently RDP only allows 2 simultaneous connections at a time.

I really need to know can I install an RDP license on this server which will allow anyone to access without them needing a license on their end. These users are RDPing from Mac's, Linux, and a few Windows PCs. These users are not always the same and change all the time.

I ran across a configuration to allow more than two but that did not work. After researching I see that an RDP license is needed. So as I mentioned above I am hoping all I need is a license on my server to expand the number of simultaneous users.

Thank you for any answers.

Bob

Hello @BobFord-6570 ,

Thanks for your query.

1.If you want to allow more than 2 simultaneously sessions, RDS deployment with appropriate RDS CALs installed is necessary.
(1) RD Connection Broker
(2) RD Session Host
(3) RD Licensing server – there is 120-day licensing grace period, appropriate RDS CALs should be purchased and installed before it has expired.

License your RDS deployment with client access licenses (CALs): https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-client-access-license

RDS cals can be purchased from Microsoft volume licensing service center:
https://www.microsoft.com/licensing/servicecenter/default.aspx

2.You could either do it with Group Policy:
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\ Remote Desktop Session Host\Connections\
Restrict Remote Desktop Services users to a single Remote Desktop Services session value: Disabled
Next, double-click on Limit number of connections and then set the RD Maximum Connections allowed to 999999.

Or you could edit the registry as follows:
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server
fSingleSessionPerUser value: 0
fdenyTSConnections value: 0

@LeilaKong-MSFT I followed the steps to add the RDP services to the 2019 datacenter server (activated with the default trial device license) and also updated the group policy and registry but I'm still getting an error when trying to do more than 2 simultaneous RDP sessions. Anything else I need to set?

I also noticed that there is only Windows 2000 TS license set in the license list, is there a trial license for Windows 2019? I thought RDS 2019 came with a 120 day trail?

Thanks
