title: DotRas error enumerating devices - RasException (Error code 1070)
body: <p>Then trying to execute the following line:</p>
  
  <pre><code>ReadOnlyCollection&lt;RasDevice&gt; list = RasDevice.GetDevices();
  </code></pre>
  
  <p>I get a very non-helpful <code>RasException (Error code 1070)</code>.</p>
  
  <p>This is also thrown when executing </p>
  
  <pre><code>RasDevice.GetDeviceByName(...);
  </code></pre>
  
  <p>I have ran the application as administrator.</p>
  
  <p>Is there a reason why enumerating the available devices may fail?</p>
