RD Licensing Configuration on Windows Server 2012 Have you installed License server on Server 2012 and you have RDS CAL of Server 2008 R2? To change the licensing mode on RDSH/RDVH: $obj = gwmi -namespace 'Root/CIMV2/TerminalServices' Win32TerminalServiceSetting $obj.ChangeMode(value) - Value can be 2 - per Device, 4 - Per user Please refer below article for information. To change the Licensing mode we can use RD Licensing diagnoser or by PowerShell command. If the license server has installed licenses of the other mode, changing the licensing mode for the terminal server may also resolve the issue.

We need to install the proper RDS CAL on the License server.

From the error description it seems that your issue caused by setting up different Licensing mode. Hi, Thank you for posting in Windows Server Forum. How can I activate licenses in trial mode? Thank you for support.
