Licensing Issues

[wightsupport]

Where you have licensed your server but it is complaining that it has either expired or that you do not have enough clients.

Try the following

PowerShell
$obj = gwmi -namespace "Root/CIMV2/TerminalServices" Win32_TerminalServiceSetting

$obj. SetSpecifiedLicenseServerList("licserver.domain.local") 

Regedit
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\Licensing Core\LicensingMode

Change the DWORD to 2 for Per Device or 4 for Per User.

Reboot
