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
Is the problem I am trying to solve. Suggestion is to make changes to the my.cnf file which I cannot find on my PC using search facility or navigating to specific directories.
Using Vista changed programme defaults to open .cnf files in notebook. Error message is from Dreamweaver CS4
Looked in mysql/bin/
I am a novice so would appreciate any help in as simple terms as possible to sort out missung file and more importantly to solve initial problem
