MySQL Error#: 1045 Not Explained

Question

I have had this error, and found a zillion posts on the web
asking for a solution, and never found a solution. But I've kind of
figured out what's going on and I'd like to know exactly how and
why it does what it does.
I have a Linux box lemon running MySQL, and a Windows XP
client orange. From orange I can connect using mysql command line
client (mysql -u root -p -h lemon mydatabase). I can also connect
using ODBC (by creating an ODBC connection in Control Panel and
testing the connection).
When I try to connect to lemon/root/password in Dreamweaver
CS3 by creating a MySQL Connection it fails with...
MySQL Error#: 1045
Access denied for user root@lemon (using password:YES)
(This is what a ton of posts complain about with lame
responses like - you got the password wrong).
So what I discover is that in Dreamweaver I have to set up
the connection using localhost instead of lemon. (NOTE: Dreamweaver
is running on orange - not lemon, where the MySQL server is
running!)
So I wonder - what the!!! The database is not on localhost.
So I fiddle a bit and find that if I go into Manage Sites and
change the name of the FTP host under Testing Server that the
connection to localhost breaks - so somehow the MySQL connection is
being made using the FTP host.
How is Dreamweaver making a MySQL connection using lemon as
the FTP server and localhost (orange) as the MySQL server, when it
is lemon that is the MySQL server???

You know that working on a DB as root is a bad idea? You
should create a
normal account for the daily work and login as root only for
maintenance
or configuration stuff.

Every machine is a localhost from its own point of view.
Since the DB
and probably your scripts both run on lemon, from their point
of view
that machine is the localhost and PHP has to open a
connection to
'localhost' in order to connect to the DB. This is the most
common setup
if PHP and MySQL run on the same machine.

But one thing confuses me. You said you can connect from your
Windows
box, using the command line:
mysql -uroot -p -hlemon mydatabase
Does the same command also work if invoked directly on the
Linux box or
does it cause an "Access denied"?

FTP is used to transfer the scripts to the server.
