title: validcfg.dll failed to load but validation set to false
body: <p>I am trying to migrate an IIS server and a web application to my machine. </p>
  
  <p>I've imported the settings from another machine, but some .dll failed to load.</p>
  
  <p>I've just installed them, but now I stuck.</p>
  
  <blockquote>
    <p>The Module DLL C:\Windows\System32\inetsrv\validcfg.dll failed to
    load.  The data is the error.</p>
  </blockquote>
  
  <p>What I really want to do is to install this dll I just do not know, what should I install from windows services.</p>
  
  <p>Under IIS there is no ConfigurationValidationModule or any like this.</p>
  
  <p>Of course I've tried to goole it, and found this <a href="https://stackoverflow.com/questions/4209999/an-asp-net-setting-has-been-detected-that-does-not-apply-in-integrated-managed-p">SO topic</a>.</p>
  
  <p>The only occure is in IIS_schema.xml and I rewrote it to false.</p>
  
  <pre><code>&lt;sectionSchema name="system.webServer/validation"&gt;
    &lt;attribute name="validateIntegratedModeConfiguration" type="bool" defaultValue="false" /&gt;
  &lt;/sectionSchema&gt;
  </code></pre>
  
  <p>I just changed the <code>Managed Pipline</code> to <code>Classic</code> in my application pool to through IIS management console.</p>
  
  <p>Restarted the IIS, but I am still getting 503, and in the Event Viewer the error appears again.</p>
  
  <p>Can anybody help me with this?</p>
  
  <p><strong>EDIT</strong> </p>
  
  <p>All the Health and Diagnostic modules are installed, but there is no file like this.</p>
