Hi everyone - I'm having a bit of an issue with RemoteFX in a VDI deployment utilizing the RDWeb and RDGateway roles.
I have a VDI deployment in a Windows Server 2012 environment where my Connection Broker and Virtualization Host are on the internal network and my RDWeb and RDGateway server (combined roles) sits in the DMZ (between two Cisco firewalls). Firewall rules are properly opened (although I think I don't have the UDP port open that RDGateway uses)
I'm using a Cisco UCS box with 256GB of RAM, plenty of storage and an nVidia GRID K2 card for RemoteFX. The drivers are installed on RDVH. RemoteFX is enabled and working on all the virtual machines (the adapter is added and being used) and it seems to run fine if I launch an RDP session from my local client to a VM in the VDI collection/pool. As a note I am running Win7 Ent SP1 w/RDP 8.0 client with local group policies modified to allow RDP 8.0. Local group policies were also modified on the RDVH, RDCB, and RDWeb/Gateway server for RemoteFX and RDP 8.0.
In addition, I also know that the RemoteFX adapter is working because when I launch an RDP session from my local client to a VM in the VDI pool I see the RemoteFX adapter in Device Manager. I also ran dxdiag and I can see that is properly using "Microsoft RemoteFX Graphics Device - WDDM" with driver version WDDM 1.0. My settings on my RDP client (mstsc.exe) is set to use LAN 10mbps or higher. Oh, and Aero Glass works via RDP.
Alright, here's where the strange issue appears:
I deployed the RDWeb server (as per the requirement of the VDI deployment option in Server 2012) and continued to install the RDGateway role on the same server that sits in the DMZ. I force my clients to connect via SSL using the RDGateway with firewall rules opened and the SSL cert working properly. Connections to my VDI pool work just fine and I can connect to the SAME VM that I previously mentioned above. My VMs in the VDI pool are assigned and managed. And as far as I know I am connecting via port 443. Of course, the RDCB manages all the connections so it appears that I'm "technically" connecting to the RDCB and not my previous VM, even though I know I am connected to my assigned VM via the Hostname command.
Anyway, When I connect to the VM via the icon that get's published in the VDI deployment, I can see that in the logs that I'm connecting at 10mbps.
When I check device manager I see the "Microsoft RemoteFX Graphics Device - WDDM" is available but when I check dxdiag it does NOT appear that I am using WDDM. Instead it shows that I'm using "RDPUDD Chained DD" with an "Unknown" driver model.
To further troubleshoot this I checked in the RemoteDesktopServices-RdpCoreTS application log on the VDI VM and noticed this warning that leads me to believe that RemoteFX is not working via RDGateway/RDWeb. There were no events whatsoever in any of the other RemoteDesktopServices logs.
"The client computer does not support RemoteFX. The connection will be made with the RDP Graphics. The relevant status code was 0x10a." - Event ID 5 - RemoteFX Module
Anyone have any ideas what the issue could be? Is RemoteFX not supported via RDGateway? Which would kind of be silly.
