404 CustomError redirect with an aspxerrorpath QueryString

 I have written a redirection 404 page that will take a user to their user page (HTTP://www.DOMAIN.com/USERNAME) . The problem is that it works well in the webdev server but not in IIS6. In web.config I have

<customErrors mode="on" defaultRedirect="Redirect.aspx">
    <error statusCode="404" redirct="Redirect.aspx"/>
</customErrors>
 Could someone please tell me what I am doing wrong...
