Also, I'm no VB expert, but try changing the following code in /archive/global.php

PHP Code:

// check to see if server is too busy. this is checked at the end of session.php
if ((!empty($servertoobusy) AND $bbuserinfo['usergroupid'] != 6) OR $vboptions['archiveenabled'] == 0 OR strpos(SAPI_NAME, 'apache') === false)
{
    exec_header_redirect("$vboptions[bburl]/$vboptions[forumhome].php");
} 


to

PHP Code:

// check to see if server is too busy. this is checked at the end of session.php
if ((!empty($servertoobusy) AND $bbuserinfo['usergroupid'] != 6) OR $vboptions['archiveenabled'] == 0 )
{
    exec_header_redirect("$vboptions[bburl]/$vboptions[forumhome].php");
} 


as the original code seems to specifically check if it is running apache. Surely this cant be the problem!
