This is an old post, but I found a GREAT fix for this issue detailed in this article >> http://www.adrogen.com/blog/wordpress-wp-blog-headerphp-causes-404-in-ie/

The code I finally replaced the “wp-blog-header.php” is here.

/***********************************************************************

* Blog Header Error Fix *

***********************************************************************/

// Include WordPress functionality

$currDir = dirname(getcwd());

// Make sure this isn’t install or admin (go up if it is)

if(!file_exists(“$currDir/wp-config.php”))

$currDir = dirname($currDir);

if(!file_exists(“$currDir/wp-config.php”))

die(“Cannot find WordPress integration files.”);

// ***** OLD Blog Header Line *****

//require_once(“$currDir/wp-blog-header.php”);

// ***** New WP Integration stuff *****

require(“$currDir/wp-config.php”);

$wp->init();

$wp->parse_request();

$wp->query_posts();

$wp->register_globals();

/***********************************************************************/

Made my life ALOT better….
