title: Can't read from RSOP_RegistryPolicySetting WMI class in root\RSOP namespace
body: <p>The class is documented in</p>

  <p>And from this page it seems it's not an abstract class:</p>
  
  <p><a href="http://msdn.microsoft.com/en-us/library/aa375084%28VS.85%29.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/aa375084%28VS.85%29.aspx</a></p>
  
  <p>But whenever I run the code below I get an "Invalid Class" exception in ManagementObjectSearcher.Get(). So, does this class exist or not?</p>
  
  <pre><code>ManagementScope scope;
  ConnectionOptions options = new ConnectionOptions();
  options.Username = tbUsername.Text;
  options.Password = tbPassword.Password;
  options.Authority = String.Format("ntlmdomain:{0}", tbDomain.Text);
  scope = new ManagementScope(String.Format("\\\\{0}\\root\\RSOP", tbHost.Text), options);
  scope.Connect();
  ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, new ObjectQuery("SELECT * FROM RSOP_RegistryPolicySetting"));
  foreach (ManagementObject queryObj in searcher.Get())
  {
      wmiResults.Text += String.Format("id={0}\n", queryObj["id"]);
      wmiResults.Text += String.Format("precedence={0}\n", queryObj["precedence"]);
      wmiResults.Text += String.Format("registryKey={0}\n", queryObj["registryKey"]);
      wmiResults.Text += String.Format("valueType={0}\n", queryObj["valueType"]);
  }
  </code></pre>
  
  <p>In the first link above, it lists as a requirement something called a "MOF": "Rsopcls.mof". Is this something I should have but have not? How do I obtain it? Is it necessary in the querying machine or the queried machine? Or both?</p>
  
  <p>I do have two copies of this file:</p>
