I am getting the following error when creating an external switch on Hyper-V:

Hyper-V Error

I am running Windows 8.1 x64.

My switch settings are as follows:

External Switch Settings

Event viewer gives me the following errors in Applications and Services Logs -> Microsoft -> Windows -> Hyper-V-VMMS in the order of logging:

1) Timed out trying to acquire network configuration lock, current owner = 'Binding Engine Task Queue Handler'.

2) Switch delete failed, switch = 'C8486DBE-CFB6-4355-99E3-19CD37C6D606': Operation times out (0x80041069).

3) Failed while removing virtual Ethernet switch.

did you solve this problem? I'm getting the same error and I have the same wireless network card :( –  andrecarlucci Mar 25 at 14:57
    
@andrecarlucci Sorry, no solution yet. I stopped using Hyper-V in the end. It would be nice to learn why this happened though... –  rhughes Jun 5 at 8:19

1)Did you try launching Hyper-V Manager with Administrative rigths? .

2) Try closing the properties Windows because your network adapter might be running another instance which is making some conflicts

None of this helped in my case. I was surprised that I was able to create Internal Virtual Switch worked after I clicked Stop Service in Actions followed by Start Service –  mlt Jun 1 at 1:45
    
I did try those options, thanks, but to no avail. –  rhughes Jun 5 at 8:19

Do you already have a switch bound to that NIC? If you don't see it in the GUI use the nvspbind.exe tool at an elevated prompt as in this Microsoft Article.

Creating V-switches within the hyper-V environment fails

It will show you what virtual switches are attached to the NIC and allow you to unbind them.
