This could also be related to a recent windows update. I recently updated to 2004 to be able to run WSL2. When I virtualized the machine I followed the recommended Oracle Virtual box steps, which included running a script to remove the disk adapter drivers. then I imaged the disk over to a VMDK. Everything on the machine runs fine, there are the occasional bugs, that don't seem related to this.

When I RDP in I get the error message below.

I have found several error messages in the Event Viewer on the Remote Machine. All of the interesting ones seem to be under RemoteDesktopServices-RdpCoreTS. Here are some of the more interesting ones in order.

  1. 'Failed GetConnectionProperty' in CUMRDPConnection::QueryProperty at 3344 err=[0x80004001]
  2. 'Connection doesn't support logon error redirector' in CUMRDPConnection::GetLogonErrorRedirector at 4657 err=[0x80004001]
  3. 'Failed GetConnectionProperty' in CUMRDPConnection::QueryProperty at 3344 err=[0x80004001]
  4. Disconnect trace:CUMRDPConnection Disconnect trace:'calling spGfxPlugin->PreDisconnect()' in CUMRDPConnection::PreDisconnect at 5073 err=[0x12], Error code:0x12
  5. TCP socket WRITE operation failed, error 64
  6. TCP socket READ operation failed, error 64

Here are some of the things I have attempted so far.

  • Confirmed IP Address
  • Disabled Firewall Attempted to disable RemoteFX via GPO https://serverfault.com/q/886027/95189 then
  • attempted to disable it via Registry. Added and then removed
    • Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\fEnableRemoteFXAdvancedRemoteApp with 0x00000000
  • Attempted to increase the Max Outstanding Connections
  • Changed RDP host hostname
    • Some research indicated something about cloning machines could confuse the network.
  • Install VirtualBox Extension Pack
    • Running 6.1.6 on everything
    • 6.1.10 seems to be the latest via Oracle, but with the Ubuntu repos 6.1.6 seems to be what they have available.
  • Disabled Nested VT-x/AMD-V
    • Something about RemoteFX requiring this feature, so I attempted to disable RemoteFX by removing its requirement.
  • Disable URCP
  • Attempt to update Hyper-V Virtual Machine Bus Provider but it failed.

  • That's too bad. My issue sounds similar... superuser.com/q/1598296/28834 Nov 1, 2020 at 1:06
  • I took a look at your first few lines... my issue isn't freezing, but rather wont connect at all. Some of those error messages are similar though. I might work on it again soon. Thanks for reminding me, I'll ping your question if I make any headway.

Solved for me:

The last thing I tried in VMware was a checkbox for that specific machine. "Accelerate 3D graphics" <- Uncheck this box.

This was a real computer that I virtualized. Windows 10 (Guest) Running on WMware Workstation 14 Pro. The host computer is running windows 7

I have been down the path of everything you have already tried. Wish I could restore every little change and just hit that box. Lost a day of work too.

  • Ok, that sounds like something I would do. Not sure if I still have that VM around, even if, I am moved on to qemu.

  • Oh wait I was using virtual box. Even still I am pretty sure I would have clicked the accelerate 3d graphics.

We noticed we had installed a VPN client on our Windows Server 2016 (Netmotion) which was also having a problem loading. Uninstalled netmotion and problem solved.

but I had also applied the registry entry you mentioned above.

so which one fixed it? don't know, but we can now RDP into our server.
