body: <p>I'm using IIS 7.5 on Windows Server 2008 R2 x64 Enterprise Edition. In the project we have developed with ASP.NET 4.0 we used WCF Service. But it doesn't run over domain when the software is running from local computer. Otherwise, I am getting the following error:</p>
  
  <blockquote>

    <p>The page you are requesting cannot be served because of the extension
    configuration. If the page is script, add a handler. If the file should
    be downloaded, add a MIME map.</p>
