This blog post introduces the Windows PowerShell cmdlets for configuring Remote Desktop licensing settings on a RemoteFX-enabled RD Virtualization Host server in Windows Server 2008 R2 SP1.

Until Windows Server 2008 R2, in a Virtual Desktop Infrastructure (VDI) deployment, the RD Virtualization Host server was not aware of licensing settings because only the RD Session Host server participated in licensing and performed license validations for the client session/connection requests. But the new licensing model for the Microsoft VDI solution (in Windows Server 2008 R2 SP1) requires that the Remote Desktop licensing mode and the list of Remote Desktop license servers be specified on all RD Session Host servers (configured in virtual machine redirection mode) as well as on all RD Virtualization Host servers (with RemoteFX enabled), because the RD Virtualization Host servers can also participate in VDI licensing.

Because there is no GUI interface for specifying licensing configuration on an RD Virtualization Host server, support has been provided in Windows PowerShell to enable this scenario. As a result, a VDI administrator who does not want the (RemoteFX-enabled) RD Virtualization Host server’s licensing settings to be centrally managed (from the RD Connection Broker server) can manually configure these settings on the RD Virtualization Host server(s) in the VDI deployment by using the following Windows PowerShell cmdlets:
