MySQL Installation Problem

[timbr8ks]

So, I just got a new computer (excellent), but I cannot connect to MySQL via my PHP pages.

Running Windows XP Pro, I've installed IIS and MySQL 4. I can connect to the database from the Command line, and PHPMyAdmin works fine. But when I try to run this code from PHP:

$link = mysql_connect('localhost', 'gareth', '[password]') or die("Could not connect");
mysql_select_db('test');

I get this result:

Warning: mysql_connect(): Access denied for user: 'gareth@localhost' (Using password: YES) in c:\inetpub\wwwroot\tbrooks\TMP2j9oqxq230.php on line 7
Could not connect

I've checked everything. Running WinMySQLAdmin, I can see that I have the user and password right. Can anyone offer any suggestions?

Make sure you have created the user "Gareth" within MySQL and grant user "ALL" privileges

Pardon me for being numb, but how do I do this? Running winmysqladmin, it tells me that gareth is the user. How do I determine whether he has the right permissions? And how do I set them?
