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.

This video is about how to remove concurrent sessions on Windows Server 2008 R2. This method is also applicable for Windows 7 Professional and Enterprise.

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. RDS and TS CAL Interoperability Matrix Hope it helps! Dharmesh Solanki.

Dharmesh Solanki. Hi Guys, The common solution is to delete the “grace period” key from the registry which is essentially a crack to allow the server to have unlimited licensing. What we found to be a working solution to the below error is the following: The Remote Desktop Session Host server is in Per User licensing mode and No Redirector Mode, but license server ServerName.domain.com does not have any installed licenses with the following attributes: Product version: Windows Server 2012 Licensing mode: Per User License type: RDS CALs The fix: Inside of RDS licensing manager right click the server and select the manage licenses option. Select the rebuilt the licensing server option and hit next. It will ask you to confirm that you wish to delete all licenses on the server so make sure you have the info needed to reinstall the RDS CALs. Once done you will have the option to reinstall the CALs, proceed as you would normally. Finally restart the “remote desktop licensing” service and head back to the RD licensing Diagnoser.
