I met this error today that states my NDISWANIP can not be accessed. The situation was weird that my network interface cards were actually brought up. But when I use IPCONFIG to view them, nothing was shown. I checked the event log and found event 4191.
I tried the solution provided by MS knowledge base but the problem persists. Then I cross compared the registry of a working computer with my non-functional one. I found a registry directory is missing on my non-functional computer, which I guess it went broken due to the enable/disable/setting of Virtual Box.
I was just about to give up but I found a way to solve it: uninstall the network devices and refresh the hardware manager. It starts to reinstall the driver and it is back to normal. I created the missing registry before I uninstall the drivers. I am not sure whether this will cause a difference, but I am happy for now and do not have plan to try it.
