you need to get to the mysql console

through DOS or your terminal or whatever you are using


and use the OLD_PASSWORD algorithm

G:\mysql\bin>mysql -u your username -p

Enter password: your password

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 1091 to server version: 4.1.14-nt


Type 'help;' or '\h' for help. Type '\c' to clear the buffer.


mysql> SET PASSWORD FOR 'your username'@'localhost' = OLD_PASSWORD('your pasword');

//If your doing it for a remote user use their IP or domain name for the localhost part

Query OK, 0 rows affected (0.03 sec)
