Hyper-V Virtual Switch Manager cannot create an External Switch RRS feed

  • Question

  • My system has two network connections, one is physical and one is Wifi.  I get the same result for both network connections whenever I attempt to create an External Switch and attach it to one of the network connections.

    The error result is:

    Error applying Virtual Switch Properties changes
    Failed while adding virtual Ethernet switch connections.

    Ethernet port
    '{2B7542A2-8652-4B62-944F-C063D6A059FD}' bind failed: {Access Denied} A process has requested access to an object, but has not been granted those access rights. (0xC000022).

    So far I have tried uninstalling/reinstalling all the network drivers and Hyper-V as well.  This is a brand-new installation of Windows 10, but the previous installation on the same hardware worked perfectly before it was re-imaged.

  • Hi Steve Sj,

    1. What is the account used to create the virtual switch, please ensure the account has rights to manager hyper services;

    2. Is the win10 patched with the latest windows updates, if not, please install updates on the windows 10;

    3. Test if disconnecting Wifi Connection could make effects to create external vswitch;

    4. Also check if re-enable the physical network adapter could help.

    Best Regards,

    Anne

  • Hi, I solved this by: In PowerShell type: netcfg -d This WILL DELETE all network adapters AND network SETTINGS! Physical adapters will NOT be LOST. Then i restored my network settings and created new External Virtual Switches. This worked for me fine and fast. Windows 10 64bit there.
