title: System.Management.ManagementException
body: <p>I am running following code: </p>
  
  <pre><code>System.Management.ManagementClass wmiNetAdapterConfiguration = new System.Management.ManagementClass("Win32_NetworkAdapterConfiguration");
  System.Management.ManagementObjectCollection wmiNetAdapters = wmiNetAdapterConfiguration.GetInstances();
  Log.logInfo("Net adapters:" + wmiNetAdapters.get_Count());
  </code></pre>
  
  <p>And on some machines it is ok, and on some I am getting following error:</p>
  
  <blockquote>
    <p>System.Management.ManagementException: Not found </p>
  </blockquote>
  
  <p>Call stack:</p>
  
  <pre><code>System.Management.ManagementException: Not found

     at System.Management.ManagementScope.InitializeGuts(Object o)
