RDS Licensing Problem - Windows Server 2012 VDI

Hello,

I am preparing this POC for Windows Server 2012 VDI infrastructure.

• 1 VM hosting RD Web Access
• 1 VM hosting RD Connection Broker
• 1 VM hosting RD Licensing
• 2 Clustered physical servers hosting RD Virtualization Host (Hyper-V)

I'm facing RDS Licensing problem

• I have installed and configured  the RDS licensing server (I've installed Windows Server 2012 RDS Per Device license).
• All RD Virtualization Hosts (Hyper-V) can see the licensing information.

The problem is no VM is asking for a certificate from the RD licensing server, nor the RD Licensing server is getting any request.

Thanks in advance
