I have a laptop that runs Hyper-V on it for development of applications. Yesterday all of the sudden I lost network connection inside one of my virtuals.
I went to the Hyper-V manager and clicked on the Virtual Switch Manager. It comes up displaying an alert box that says 'An error occurred while trying to retrieve a list of virtual switches. The operation on computer 'localhost' failed.
After some fiddling I noticed that in the device manager there are 5 anomalies.
-Under Network adapters, the 'Microsoft Hyper-V Network Switch Default Miniport' has an alert by it because it's driver is giving a code 39
-There is now an unknown device listed. It traces to ROOT\VMBUS. This device is not there in between installing Hyper-V so it is related to it somehow.
-3 devices under 'system devices' have the yellow alert and give a code 39. Hyper-V PCI Server, Hyper-V Virtual Disk Server, Hyper-V Virtualization Infrastructure Driver.
Trying to update the drivers does not work. Windows reports back that the drivers are current and up to date. I cannot uninstall the Network Switch Default Miniport. I try to click it, it asks if I want to uninstall, but does nothing. Tried again making sure that Hyper-V service was not running to no avail.
Tried uninstalling and re-installing Hyper-V but it always comes back the same.
