 * Hi,
 * I’m installing WordPress in IIS.
 * I’ve installed MySQL on my PC. I’ve setup IIS and downloaded WordPress.
 * I can browse to the website using localhost and the WordPress setup begins.
 * The issue is, I’ve tried every possible combination of information for the Database
   Name, UserName, PassWord, DatabaseHost but I keep getting “Error establishing
   a database connection”
 * If I’ve setup a new instance of MySQL on my PC, what information do I need in
   these boxes in order for WordPress to continue the setup?

 * try using 127.0.0.1 instead of localhost
    for DB_HOST make sure you allow mysqld.
   exe to listen on port 3306 (windows firewall) make sure mysqld is running, check
   the mysql.err (error log) for possible debug information. make sure you can use
   mysql.exe (command line client) and connect to DB server `mysql -h 127.0.0.1 -
   u user -p password` from windows command line console
