Thanks to Thomas.The problem fixed. I download the PHP mysql extensions from mysql.com,put libmysql.dll into ext,and then add "C:\php5\ext" to %path%.

To Wanat, David A: It's unnecessary to modify the target of the form action.Just add "index.php" into the default content document of IIS.

I'm having the same problem.

I've tested my MySQL with the following page http://www.wanat.net/db.php It connects to MySQL and returns a result.

To the guys whose name I can not type... Once you get past that make sure you modify the <form action=" "> to <form action"index.php"> on the login page (and maybe all others) because IIS won't return it to that page unless you specify the action.

Looks like the MySQL extension for PHP does not work correctly. Do you have other PHP applications using MySQL (like phpMyAdmin) on your server?
