PHP/MYSQL Error

I've installed PHP 4.4.1 and MYSQL 4.1.10 onto a server machine but upon running a simple login script (that works fine on a test machine running PHP 4.4.1 and MYSQL 4.0.23) I get the below error.

Upon checking mysql.com it's says to upgrade to MYSQL 4.1.10 or above but I am already running that version. Does anyone know how I can overcome this error and connect to my database?

PHP Code:

Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client in C:\Apache Group\Apache2\htdocs\poll\db_connect.php on line 19
