 O/S: Windows Server 2008 with IIS7.0

 Symptom:
 Every time a redirect happened a 404 error page would show up before the
 redirected page comes up.

 in wp-includes/pluggable.php:
 {{{
         if ( $is_IIS ) {
                 header("Refresh: 0;url=$location");
         } else {
                 if ( php_sapi_name() != 'cgi-fcgi' )
                         status_header($status); // This causes problems on
 IIS and some FastCGI setups
                 header("Location: $location");
         }
 }}}

 Sending a Refresh  to the IIS server caused it to happen.  So to fix it I
 basically just did header("Location: $location"); as below but that didn't
 seem too sanitary so I instead went to the wp-includes/vars.php where it
 determined what was exactly IIS and just put this in:

 {{{
 /**
  * Whether the server software is IIS or something else
  * @global bool $is_IIS
  */
 if (strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS')) {
         if  (strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS/7.0')) {
                 $is_IIS = false;
         } else {
                 $is_IIS = true; // (strpos($_SERVER['SERVER_SOFTWARE'],
 'Microsoft-IIS') !== false) ? true : false;
         }
 } else {
         $is_IIS = false;
 }

 }}}}
