Apache moved to IIS6... Frontend login fine but admin loop

[samatgopublic]

I am sorry I know there are so many related topics already... But I 've tried most of the methods but still not work.

Actually I even tried,

1. installed a clean Joomla 1.5, but have the same admin loop problem.
2. asked hosting to ensure the session.save_path is writable.
3. Write a simple code to test "Does the SESSION really work". The result is YES. The code as below,

if ($_SESSION['counter'] == "")
$_SESSION['counter'] = 1;
else
$_SESSION['counter'] = $_SESSION['counter'] + 1;

echo "<p>SESSION TEST: ".$_SESSION['counter']."</p>";

The counter changes every time I refresh the page.

So I guess the server 's SESSION does work, but just failed in the Joomla backend admin.

I also print_r($_SESSION) at the bottom of administrator/index.php

the session doesn't store my login info.

But I also print_r($_SESSION) in the admin.login.php, it did save the user info to SESSION before redirect to index.php. Just after redirected, all session killed....

I am not familiar with IIS. I used to Apache only. It never happens in Apache.

Please advise... Many Many thanks.

Makes sure that all of the options concerning SEO are turned off (set to 0) in global configuration. If you can't get into the administrator side you will need to edit the configuration.php file directly.

Hi dhuelsmann, thanks for your help!!!

I am sure I didn't turn on the SEO options. And I have installed a clean Joomla 1.5. But still have the same problem.

I just don't understand why the SESSION works on standalone php scripts but Joomla.....
