One common error message that you might encounter when testing a PHP database connection to MySQL 4.1 is “Client does not support authentication protocol requested. Consider upgrading MySQL client.”

You may have to revert to an earlier version of MySQL, or install PHP 5 and copy some dynamic link libraries (DLLs). For detailed instructions, see Install a PHP application server.
