Is the database running? Is it running on port 3306? Is there a firewall active blocking the port? Are you attempting to connect to the right host? Are you attempting to connect to 3306? Are you using the correct tablename in the connection url? Is the username and password correct? Is MySQL configured to allow that user, with that password, to connect from where the user is attempting to connect from?

I think that pretty much covers the possibilites.
