Error upgrade php 5.3.x and cannot connect to MySQL 4.1+

[SystemError]

I recently installed the Plesk 9.3.0
and upgrade php 5.3, mysql 5.5.33 and phpmyadmin 3.4.10.2.
i try connect mysql and get results:

#2000: mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file

i use windows server 2003 sp 2
here is my php.ini and my.ini file:
