title: HTTP Error 403.14 - Forbidden in asp.net visual studio 2012
body: <p>I was editing my CSS code and every thing was OK for hours but just for once i saved the code and reloaded the web page  this error (HTTP Error 403.14 - Forbidden) appeared. 
  i don't know what's wrong with it and why such problem appeared suddenly.
  - I tried to use microsoft suggestion:  <a href="http://support.microsoft.com/kb/942062" rel="nofollow">http://support.microsoft.com/kb/942062</a> but directory c:\windows\system32\inetsrv is empty (!) so inetmgr.exe could not be opened. - adding these to web.config:</p>
  
  <pre><code>&lt;system.webServer&gt;
      &lt;modules runAllManagedModulesForAllRequests="true"/&gt;
    &lt;/system.webServer&gt;
  </code></pre>
  
  <p>wasn't useful too.and setting the <code>&lt;modules runAllManagedModulesForAllRequests="false"&gt;</code> does not make any changes.I updated visual studio 2012 and it wasn't useful too.
  (IIS 8.0 express  seems to be installed correctly , also visual studio 2010 is installed on my machine).
  later I found out that if more than one vs2012 is opened this error could be displayed.</p>
  
  <p>thanks in advance...</p>
