Terminal server does not have any installed licenses


  • Good morning! Faced with a some trouble while configuring Terminal Server (Windows Server 2012 based). I selected licensing mode "Per User" and now I see this message:

    “The Remote Desktop Session Host server is in Per User licensing mode and No Redirector Mode, but license server “server name” does not have any installed licenses with the following attributes:

    Product version: Windows Server 2008 or Windows Server 2008 R2

    Licensing mode: Per User

    License type: RDS CALs”

    So this is trial using of terminal server - I have 25 days yet but already today I can't connect to server using RDP. There is an error message about absent licensing server. How can I activate licenses in trial mode? Thank you for support.

  • Hi,

    Thank you for posting in Windows Server Forum.

    From the error description it seems that your issue caused by setting up different Licensing mode. We need to install the proper RDS CAL on the License server.  If the license server has installed licenses of the other mode, changing the licensing mode for the terminal server may also resolve the issue. 

    To change the Licensing mode we can use RD Licensing diagnoser or by PowerShell command. 

    To change the licensing mode on RDSH/RDVH:

    $obj = gwmi -namespace "Root/CIMV2/TerminalServices" Win32_TerminalServiceSetting
    $obj.ChangeMode(value) - Value can be 2 - per Device, 4 - Per user

    Please refer below article for information.
    RD Licensing Configuration on Windows Server 2012

    Have you installed License server on Server 2012 and you have RDS CAL of Server 2008 R2?
    If that’s the case then first you need to purchase the RDS CAL for server 2012 and then you can configure on server 2012 because server 2012\R2 RDS CAL can work with lower version OS but Server 2008 R2 RDS CAL can’t work on Server 2012\R2.

    Please check computability matrix.

    Hope it helps!
