I have IIS installed with an existing MySQL version on my server computer. Now I want to install WAMP to host magento sites.

After I installed WAMP and changed the apache port from 80 to 8090, all the magento sites siting on wamp server works fine. But all my IIS php sites cannot connect to the old MySQL database.

So I was requested to change the port of the new MySQL in WAMP.

I changed the my.ini file with the new port number 3307, then I restarted wamp service. The server icon is green, but when I visit the phpMyAdmin page, I got an error message saying "#1045 - Access denied for user 'root'@'localhost' (using password: NO)".

I searched on goolge and changed the config.inc.php file with port = 3307, restarted service again. But I still got the same error.

Is there anything else needs to be changed to get it working on the phpMyAdmin page? Thanks in advance.
