xRDLicenseConfiguration: ConnectionBroker required.

[NemoDima]

Details of the scenario you tried and the problem that is occurring

For my purposes, I need to set a few settings in gpedit.msc Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Licensing:
1.
a) Use the specified Remote Desktop license servers parameter switch to Enabled.
b) License servers to use , set localhostname or its own IP-address.
2.
a) Set the Remote licensing mode parameter switch to Enabled.
b) Specify the licensing mode for the RD Session Host server field set to Per Device.

I planed to use xRDLicenseConfiguration to set these settings but it requires installed RDS-Connection-Broker component and set ConnectionBroker.

But all this result I can get manually only with installed RDS-Licensing, RDS-RD-Server and using gpedit.msc .

Tell me please, how I can get same result using xRDLicenseConfiguration only?

Suggested solution to the issue

Make ConnectionBroker as optional parametr.
