Error Import database

[dc25]

I have just intalled Apache 1.3, Mysql 4.0, and PHP 4.3.4 on my Windows 2000 server. After I entered info in the OsCommerce install.php, the database import page, I get the following error.
------------------------------------------------------------------------------------
New Installation

Database Import

A test connection made to the database was NOT successful.

The error message returned is:

Access denied for user: 'admin@server1.HSCHEN.COM' (Using password: YES)

I have created a blank database called oscommerce from the mysql prompt and used WinMySQLAdmin to set username and password in my.ini. I am not sure where I did wrong. Any help will be greatly appreciated! Thank you.
