Description:
------------
there is a problem with session variables management on my hosting solution . my hosting solution is runnig under windows 2000 and IIS 5.x and i cannot change the hosting plan at this time , the bug is that my session variables are set when i moves between pages in same folder in which i have set the session but when i travese to a page which is in the subdirectory somehow my session variables are lost and they appear again when i jump to parent directory  .... this problem is only under windows 2000 because i am running windows xp and IIS 6 on my home PC and the session variables are working fine reagrdless of how much i traverse .... can i remove this bug somehow on windows 2000  .... following is the code i am using to check to initialize and check session variables .... my session.cookie_path = / is set and u can vies my php.ini at www.smartqatar.com/test.php

Reproduce code:
---------------
////// to initialize session variables
$row = $db->sql_fetchrow($result);
setcookie("loggedin", "TRUE", time()+(3600 * 24));
setcookie("mysite_username", "$username");
echo "You are now logged in!<br>"; 
session_start();
$_SESSION['username'] = $username;
$_SESSION['password'] = $password;
$_SESSION['fullname'] = $row['fullname'];

///// to chech session variables
   session_start();
   session_cache_limiter('private');
   header("Cache-control: private");
// session variables are not set
   if (isset($_SESSION['username']) && isset($_SESSION['password']))
        {
            $username = $_SESSION['username'] ;
            $password = $_SESSION['password'] ;			}

Expected result:
----------------
session variables should be under windows 2000
