session value not passing

[shaky]

session registered value is not passing to other script pages.
i'v already initialize php.in file as
i'v edited php.ini file for session managment as,

session.save_handler = "files"
session.save_path = "/Sessions"
session.auto_start = 1
session.use_trans_sid = 1

i'm using session_start(); as a first statement where i'm fetching.

i'm working on Win2000 and IIS server
is there any other changes in php.ini file ?
Plz help me

this is my php.ini (linux though)
session.auto_start = 0
session.cookie_path = /
session.serialize_handler = php
session.use_trans_sid = 1

so something like this doesn't work?

file1.php

$var = "Hello";

$_SESSION['var'] = $var;

file2.php

session_start();
echo $_SESION['var']." world";

or you can alternatively show us some of your code.
