Has anyone else noticed that the password expiration notification doesn't alert the user when their password is about to expire?

We have blocked access to the taskbar for students so they cannot see the keys which display. To be honest, staff are even missing it and we are missing the pop up which tells you how long you have left until you need to reset your password.

I was wondering if anyone has found a way to show this message as a notification at logon?

I see that there is a vbscript that can run at user login but i would really like a pop up box to display where they can change their password if needed like in windows xp.

Thanks
