Hyper-V - "Video Remoting Was Disconnected" Error

Started to get the error "Video Remoting Was Disconnected" when connecting to a Hyper-V VM using the Admin Console on a local machine (Connecting to the VM via RDP worked fine). All of the more relevant fixes talk about changing the settings on the NIC card which seemed a bit far fetched however I tried them all and none work.

First off my config.

  • Windows 10 device connected to an AD domain
  • My domain login account has domain admin privileges
  • My domain login account is part of the local computers Builtin Administrators group

The problem eventually was solved by resetting the C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys folder permissions using the following commands

md c:\temp

icacls C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys /t /c > c:\temp\BeforeScript_permissions.txt

takeown /f "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys" /a /r

icacls C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys /t /c /grant "NT AUTHORITY\System:(F)"

icacls C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys /t /c /grant "NT AUTHORITY\NETWORK SERVICE:(R)"

icacls C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys /t /c /grant "BUILTIN\Administrators:(F)"

icacls C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys /t /c > c:\temp\AfterScript_permissions.txt

Restart-Service TermService -Force

I also rebooted the machine just in case.

I think that something must have been weird-ed out when I joined the computer to the domain / renamed it or something along those lines.

This is not a definitive way to solve this problem as it was a last attempt to fix the issue when all other suggestions failed. You have been warned! lol

Windows 7 on my HP EliteBook 8530p

I was able to install Windows 7 Professional (x64) on my Dev laptop today.  It didn’t take that long to install and once up and running I had 6 Unknown Devices present in the Device Manager.  All I had to do for 4 of them was right click on the device and Update Driver from internet.  Windows Update recognized the 4 devices and downloaded drivers for them.  This is a list of the drivers that had to be downloaded or installed manually:

  • Ricoh Memory Stick Host Controller (driver downloaded from windows update)
  • Ricoh SD/MMC Host Controller (driver downloaded from windows update)
  • Ricoh xD-Picture Card Controller (driver downloaded from windows update)
  • AuthenTec Inc. AES2810 (Finger print sensor) (driver downloaded from windows update)
  • HP Drive Guard Driver (download HP 3D Driveguard (Vista) softpaq sp39410.exe)
  • Direct Application Launch Button (download HP Quick Launch Buttons (softpaq sp43616.exe))

Once the drivers where updated manually I noticed that I had 4 new Windows Updates to download all of which were the following drivers:

  • A newer AuthenTec Inc. AES2810 driver
  • A newer ATI Mobility Radeon HD 3650 driver
  • A newer Intel(R) 82567LM Gigabit Network Connection driver
  • A newer Agere Systems HDA Modem driver

All in all a pretty clean and simple install.  That probably more so because the the hardware is fairly new.

The only thing that does not work properly is the mute button (part of the quick launch buttons).  Not a big deal I will probably just have to update the software when HP updates its library for Win7 in October.  Other than I am really liking Win7 so far on this laptop, it runs very well alongside the 8GB of RAM I have installed.

Update: 2009-08-08 - Seems I was wrong about the mute button it does work, however it does not register to Windows that the mute button is enabled so Windows does not display the little red disabled symbol on the speaker icon in the notification area.

Update: 2009-08-29 – I was able to get the AuthenTec Inc. AES2810 finger print reader setup to login to Windows 7 with my fingerprint, it works like a charm.  To do this you will need to download the BETA version of the enrolment software here:

The blog site Three Wise Men has a tutorial on how to actually install, setup and enroll your finger print so you can start using this feature.

Update: 2009-10-22 - HP has started to release updated drivers for the 8530p which the new audio driver has fixed my mute button issue listed above.  As of todays date (2009-10-22) there are no Windows 7 Professional (x64) drivers.  I have installed the Windows Home (x64) drivers and they seem to work as expected.  Visit the HP site here.

Site up up up and away

Finally got a real site up, decided not to roll my own but try out a ready made blog engine.  I already rolled a home brew site willyd.ca which I will be slowly moving away from that site over time.

I have added some of my tech blogs from my other web site just for content, look for some interesting topics and items soon.
