title: How to restore DNN Backup
body: <p>I have taken DNN 6 backup in the following ways</p>
  
  <ol>
  <li>Copy the DNN folder from C:\inetpub\wwwroot</li>
  <li>Take Sqlserver 2008 Enterprise edition database backup</li>
  </ol>
  
  <p>When I try to restore it, I am getting error:</p>
  
  <blockquote>
    <p>Connection Error(s): Index #: 0 Source: .Net SqlClient Data Provider
    Class: 14 Number: 18456 Message: Sql login failed</p>
  </blockquote>
  
  <p>I am using the following link for restoration:</p>
  
  <pre><code>.../Install/InstallWizard.aspx
  </code></pre>
  
  <p>Note !!! When i change the database and username, it will install the fresh installation but not restoring backup database.</p>
  
  <p>How to solve this problem?</p>
