DotRas error enumerating devices - RasException (Error code 1070)

Question

Then trying to execute the following line:

ReadOnlyCollection<RasDevice> list = RasDevice.GetDevices();

I get a very non-helpful RasException (Error code 1070).

This is also thrown when executing

RasDevice.GetDeviceByName(...);

I have ran the application as administrator.

Is there a reason why enumerating the available devices may fail?

Have you found a solution for this?? I'm facing the same issue — Valerio, Jan 06 '15 at 10:04
No I didn't figure this out. I was having the problem on Windows 8.1 x64 and the same code worked without error on XP. Please do post a solution if you find one. — gunwin, Jan 06 '15 at 13:23

In my case the problem was the WAN miniport, so I checked them into Device Manager and had a little yellow Icon on them saying

"This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)".

So after some hours of research I came across this website and it gave a solution that solved my problem. I'll post it here, maybe It can help you.

and these are the istraction you've to follow:

I hope this can help!
