10060 is a Winsock error code meaning "connection refused".  It means 
the server is either a) not running, b) running but not listening on the 
port number you're using, or c) running but bound to a different IP 
address than the one you're using.

After reading your subsequent message, it's 'c' in your particular case: 
the server is listening only on the localhost IP address, so only 
programs running on the same machine can connect to it.  The connection 
is being rejected down in the network stack; the MySQL server never even 
sees the attempt.
