Hi,

I have a little problem migrating from virtualbox to hyper-v

My host OS is Windows-10, got hyper-v installed and running a guest Windows-10
Within the guest OS i'm trying to setup a remote connection to another desktop, which fails, saying its not supported. (it has connection to the internet and can ping th e desktop and the desktop can be accessed with rdp)

Is there a workaround for this ? (in virtualbox this setup works)

Kind regard
Andre

    Hi,

    Please check if the following method could work:

    Go to Run –> gpedit.msc to open Group Policy Editor.
    Go to the following policy path:
    Computer Configuration -> Administrative Templates -> System -> Credentials Delegation

    From the right-hand pane, open Encryption Oracle Remediation.
    Select Enabled and set the protection level to Vulnerable.

    Go to command prompt and run the following command:
    gpupdate /force
    This will apply the group policy immediately and you will be able to use Remote Desktop without restarting the computer.

    Thanks for your time!
    Best Regards,
    Anne

    I managed to solve it by updating Windows to the latest version (my mistake not doing this imediately after install)

    Thanks for the help!

    Kind regards,
    Andre

    Hi,

    On the Windows 10 VM, please check if we enable remote desktop in the below setting:

    Open file explorer > right click "This PC" > "Remote Settings" > "Remote Desktop" :

    If after enable the remote desktop, we are still unable to connect to the VM, please provide the detailed error message when connect.

    Thanks for your time!

    Hi,

    I checked the setting and it allows remote connections with Network Level Authentication.

    The NLA seems to be the issue. I cannot disable it (company policy).
    26406-error.png

    I forgot to mention that from the guest OS I connect to my company's network (cisco anyconnect VPN)

    Message from eventviewer :
    Application and Services Logs->Microsoft->Windows->
    TerminalServices-ClientActiveXCore:

    RDPClient_TCP: An error was encountered when transitioning from TcpStateExpectingX244CC to TcpStateFailure in response to TcpEventErrorProcessingX224CC (error code 0x80004005).

    RDP ClientActiveX has been disconnected (Reason= 519)

    RDPClient_SSL: An error was encountered when transitioning from TsSslStateHandshakeInProgress to TsSslStateDisconnecting in response to TsSslEventHandshakeContinueFailed (error code 0x80004005).

    The weird thing is that it all works on Virtualbox (no changed settings) and the same thing not working on Hyper-V

    I tested it on a hyper-v type 1 and type 2 Windows 10 enterprise installation.

    • checked that NLA service is running.
