strange session problem!

[mfacer]

hi,

I use the following to set the login session:

$_SESSION["login"] = $username;
$_SESSION["security"] = "1";

then on my admin.php page, I use this:

if ($_SESSION["security"] != "1")
{
header("Location: login.php?error=2");
exit();
}

now.... the above works perfectly on my personal web server (IIS) using WinXP, PHP version 4.2.2

but it doesnt work on my W2k server (NT5.0, php4.2.2)

any ideas why??
register_globals are both ON on both servers...

cheers.....
