http://localhost/w_wordpress/wp-admin/install.php died!

I am using IIS server on Windows7, I am trying to set up word press but run into problems with MYSQL. Can someone please give me some pointers? Thanks in advance.

Trying to point to my installation at: http://localhost/w_wordpress/wp-admin/install.php

I got this

***********************************************************************
Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

I confirmed that the user is set up in mysql.
