    Network adapter not working after setting up hyper-v lab


    Hi, I saw an article on your website regarding issue with hyper-v and was hoping for help with my issue.
    Basically I have created a lab environment on my laptop with:
    1) one 2019 server VM, AD DS installed and domain created and static ip for the DC
    2) two win10pro VMS
    3) One Virtual switch used for external connectivity to server and other VM's using my computer's NIC
    4) One private switch for VM's to join to internal domain.

    The issue is it completely messed up my computer's NIC, it has no connectivity no matter what I have tried. I then tried an external usb adapter and restarted and it did exactly the same. I ended up removing all the switches and there is no change.
    I have done a fair amount of googling but nothing really helps.

    I hope you can help

    Regards

  2. Hyper-v feature

    Hello,

    I am using Hyper-v to create virtual machines (windows/linux) for testing

    I did enroled to a class and we have to use virtualBox to import ready machines (*.ovf) files for our training and labs.

    I did disable Hyper-v feature in my windows but all Hyper-v network adapters still exist and i cannot remove them.

    Hyper-v network adapters causing conflict with virtualBox adapers and its not working at all.

    How I can clean all Hyper-v network adapers please ?

    Hyper-V Network Adapter Bridge Mode?


    I'm running successfully running Android BlueStacks in a Hyper-V machine and have network connectivity through the host adapter. However, one Android app I run does not fully function because it believes the device is not on the same subnet as the actual host machine. Someone on another forum indicated that the host adapter needed to be in bridge mode, thus ensuring that the virtual machine is on the exact subnet as the host and other device attached to the router. They suggest using something busybox for the VM and set the network adapter to bridge mode, but I really don't want to add that to my machine.

    So the question is: does Hyper-V provide a bridge mode setting for the (virtual) network adapter?

  4. Network adapter not working after setting up hyper-v lab

    Hyper-V networking

    Windows 10 Pro, Build 10586.71. Hyper-V installed. All was working well, and then I got a chipset update from Dell. Installed the update and rebooted computer. After that networking was not working correctly, windows showed limited connectivity. I looked
    a little to roll back the driver update, but Windows did not show a new Nic card driver and the chipsets I looked at also did not show a current date. The Dell Command update program does not provide a way to uninstall updates.

    I tried to access hyper-v switch manager but it returns an error that "an error occurred while trying to retrieve a list of virtual switches". Also tried using the powershell cmdlet but got a general error.

    I accessed the networking center and deleted the Hyper V adapter, then edited my LAN card's config disabling the two Hyper V protocols and enabling the rest. This let me get back on-line with my computer. I have tried uninstalling the Hyper V feature,
    reboot, reinstall - but I am still unable to access the switch manager. I then removed the feature again, re-named the C:\ProgramData\Microsoft\Windows\Hyper-V directory, rebooted, added the feature again. This time (obviously) none of my VM's show up but
    I'm still unable to access the switch manager.

    There is no critical data in my Hyper V, I use it for testing, re-creating issues, learning, etc. Is there a way for Windows 10 (or something designed for server 2012 that will apply) that I can use to fully reset the Hyper v networking, or fully rest all
    of hyper v so I can get it working again? I do use the workstation heavily, it's my work computer so it would be very difficult to impossible to reinstall the OS.

    Thoughts and suggestions appreciated.
