MySQL 5.1.31 running on Windows XP.

From the local MySQL server (192.168.233.142) I can connect as root as follows:

>mysql --host=192.168.233.142 --user=root --password=redacted

From a remote machine (192.168.233.163), I can see that the mysql port is open:

# telnet 192.168.233.142 3306
Trying 192.168.233.142...
Connected to 192.168.233.142 (192.168.233.142).

But when trying to connect to mysql from the remote machine, I receive:

# mysql --host=192.168.233.142 --user=root --password=redacted
ERROR 1045 (28000): Access denied for user 'root'@'192.168.233.163' (using password: YES)

I have only 2 entries in mysql.user:

Host         User     Password
--------------------------------------
localhost    root     *blahblahblah
%            root     [same as above]

What more do I need to do to enable remote access?

EDIT

As suggested by Paulo below, I tried replacing the mysql.user entry for % with an IP specific entry, so my user table now looks like this:

Host             User     Password
------------------------------------------
localhost        root     *blahblahblah
192.168.233.163  root     [same as above]

I then restarted the machine, but the problem persists.
