title: There was an internal error when querying iis 7.0 for profiling
body: <p>I have a WCF Service that is running too slow.</p>
  
  <p>I wanted to profile it, so I followed the instructions found here:  <a href="http://msdn.microsoft.com/en-us/library/2s0xxa1d.aspx">http://msdn.microsoft.com/en-us/library/2s0xxa1d.aspx</a></p>
  
  <p>When I try to start up the profiling I get this error:</p>
  
  <blockquote>
    <p>There was an internal error when querying IIS 7.0 for profiling. Ensure that you have all of the following Internet Information Services (IIS) and IIS 6 Management Compatibility components installed:</p>
    
    <p>Web Server,</p>
    
    <p>Windows Authentication,</p>
    
    <p>ASP.NET,</p>
    
    <p>IIS Metabase Compatibility,</p>
    
    <p>IIS 6 WMI Compatibility,</p>
    
    <p>IIS 6 Scripting Tools</p>
  </blockquote>
  
  <p>The service runs just fine normally.  Do I really need to install IIS 6 stuff to get the profiling to work?</p>
