Windows 10 Enterprise virutal machines frequent disconnects due to RemoteFX on Hyper V RRS feed

  • Question

  • Hello,

    We run Windows server 2016 on our host machines, and we connect to our hosts through an remote desktop gateway, we have run into an issue where users who remote in through the gateway are getting disconnected for about 5-10 seconds and then their session is restored. This happens about once every 30-60 minutes.

    Event viewer is throwing the following errors

    Disconnect trace:CUMRDPConnection Disconnect trace:'calling spGfxPlugin->PreDisconnect()' in CUMRDPConnection::PreDisconnect at 4726 err=[0xc], Error code:0xC

    'Failed GetConnectionProperty' in CUMRDPConnection::QueryProperty at 3015 err=[0x80004001]

    I get flooded with these events about 100 times a minute, (not each event, just a collection of related events in one minute).

    I'm looking for a way to disable remotefx so the host will not allow the client computers to use remotefx anymore. I tried a few things such as 

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations
    DWORD: fEnableRemoteFXAdvancedRemoteApp: 0x00000001 (0) - On remote gateway server

    The DWORD above is not on any of my host machines, I was concidering adding it and setting the value to zero, but I'm not sure if this will do the job.

    I also tried to disable this in group policy,by disabling everything remoteFX related other than the remotefx entry related to compression algorithms.

    Has anyone delt with this before? I would greatly appreciate any guidance.
