Unable to install hyper-V role on my remote desktop server

Hi,

I'm trying to add Hyper-V to our remote desktop server: we have another machine that is specifically an Hyper-V server, and one of the virtual machines is our phone system. I would like to have the Hyper-V role added to our remote desktop server used to manage our accounting software, so that if the hyper-V server was to crash, we can start the phone system machine on the RDP server through Hyper-V.

This is the message I'm getting, trying to add Hyper-V:

PS C:\Windows\system32> Install-WindowsFeature -Name Hyper-V -IncludeManagementTools

Install-WindowsFeature : The request to add or remove features on the specified server failed.

Installation of one or more roles, role services, or features failed.

The referenced assembly could not be found. Error: 0x80073701

At line:1 char:1

  • Install-WindowsFeature -Name Hyper-V -IncludeManagementTools
  •

    Exception

    + FullyQualifiedErrorId : DISMAPI_Error__Failed_To_Enable_Updates,Microsoft.Windows.ServerManager.Commands.AddWind

   owsFeatureCommand

Success Restart Needed Exit Code Feature Result

False No Failed {}

DISM function (/RestoreHealth) and SFC /scannow did not help.

Thanks,

Frank

    Hello,

    If you are not using a core-mode windows system, we could install it via server manager, so that we can know the process more clearly. If there's any error, we will know the process it occurred on.

    Ultimately, before proceeding, ensure you've checked your server's requirements as certain features might not be activated by default.

    Hi - I have tried installing Hyper-V from server Manager. It fails unfortunately.

    I have verified requirements, here's the result:

    Hyper-V Requirements: VM Monitor Mode Extensions: Yes

                           Virtualization Enabled In Firmware: Yes

                       Second Level Address Translation: Yes

                       Data Execution Prevention Available: Yes

    Would you have a next step you'd like me to look at?

    Thank you for your help,

    Frank
