No connect - error 111

[Figmo]

I have MySQL 4 running on a Win2K3 Server. I can connect to it from
MySQL Control Center running on a client PC on our network. But I
cannot connect to it from the outside world. Get the "can't connect
(111)" error.

The permissions table has a user "user@%" in there and this user has
global access to everything.

If I Telnet to the MySQL port from the outside world I do get a
connection and the MySQL version echoed back to me so the port appears
to be open (not a firewall issue).

But trying to connect with the following command will not work:

mysql -h server.name.com -p 8123 -u user

It prompts for password - then gives the "can't connect (111)" error.

Neither can I connect to it from the outside world through code in PHP
(same error returned)

This error number seems to be a catch all - meaning "can't
connect"....period

Is there some way I can get more meaningful information as to WHY it
can't connect? Bad password?? Bad user name?? No permissions??

It would really help me track this problem down if I knew more about
why it is unable to connect.
