title: Web.config Authentication Error
body: <p>I am using SQLServer2005 and VS2008.  My connection string in web.config is:</p>
  
  <pre><code>add name="library" connectionString="Data source=KMT; Initial Catalog=Library;Integrated Security=SSPI"
  </code></pre>
  
  <p>Here, KMT is my server name, Library is my database.</p>
  
  <p>When I run my page through VS2008 localhost, it's fine.  However, when viewing through IIS it shows an error message like "login failed for user, 'KMT/ASP.NET'".  My sqlserver authentication mode is windows and it's ok in web.config.  What will be the solution?</p>
