Windows Server 2012 Used: Error Message from Windows 7 PC: Remote session was disconnected because there are no remote desktop license servers available to provide a license. Please contact the server administrator. RRS feed

  • Question

  • We are using Windows Server 2012 Standard installed in VMWare / Virtual machine and to access this we use vSphere client and Remote Desktop Connection / service was already enabled and was working fine with User PCs / laptops remote desktop into the server 2012, until it gave an error message of: Remote session was disconnected because there are no remote desktop license servers available to provide a license.  Please contact the server administrator. whilst logging into the server. 

    We DON'T use Active Directory nor and we don't use domain and not looking to use it any-time soon. 

    I checked the RD Licensing Diagnoser and it says the grace period has expired and the licensing mode for the remote desktop session host server is not configured.  I have checked the Remote Desktop Gateway has been stopped and I tried to start it and it resumed to stop, here I assume its where the licensing part comes in to re-enabled this. 

    I have been trying to follow these articles online: and  the overview part that I cannot get into, because I think we have to be is AD DS for this which we don't.  Is there a way around this for non domain / just standalone set-up?  Is it a must / requirement we need to be in a domain in order for Remote Desktop Connection to work? 

    Also, we have a Windows Server 2012 RDS CALs - 10 (software and licence key), will the licence key work for the Windows 2012 Server Standard?  We do not want to install the other Server mentioned which comes with CAL / licence key as its time consuming to reinstall other programs.  I have installed  Server role service of Remote Desktop Licencing and automatically installed other associated services needed.  in the RD Licencing Manager, the Server had a red cross and I "Activate Server" where I followed: in Install Licences section and I have used the licence key of CAL - 10 mentioned above; it stated I have successfully completed the install licences wizard and displayed: 10 Windows Server 2012 - RDS Per User CAL installed, and in the RD Licensing Manager the server turned into a green tick and added the licence.  

    I then tested the Remote desktop connection from my PC and the same error message was there and checked the RD Licensing Diagnoser and the same error messages was there.  I haven't restart the services of Remote Gateway / the server itself; do I really need to reboot server?  

    Any advice / guidance would be very much appreciated and this is a urgent matter.  

    Thank you for your time.
