Mysql - access denied for user

I have a big problem with the Mysql server running as a service.
I work with IIS, php, Mysql and installed mysql-4.0.16-win.
IIS works fine. The rootdirectory is d:\wwwroot (localhost)
With an anonymous login and using Mysql Control Center a made a database with 2 tables with are stored in the directory c:\mysql\data.
I tried to make a connection in Dreamweaver 2004 but DW generated an internal server error.
I cannot login the mysql server although I installed a user (see the my.ini).

When I log in at the command prompt (c:\mysql\bin\mysql.exe -uroot -pazerty) I get the message: Error 1045 Access denied for User <Using password: YES>
When I log in anonymous I get the Welcome message.

This is the my.ini:
#This File was made using the WinMySQLAdmin 1.4 Tool
#19/12/2004 19:33:41

#Uncomment or Add only the keys that you know how works.
#Read the MySQL Manual for instructions

[mysqld]
basedir=C:/mysql
#bind-address=192.168.0.143
datadir=C:/mysql/data
#language=C:/mysql/share/your language directory
#slow query log#=
#tmpdir#=
#port=3306
#set-variable=key_buffer=16M
[WinMySQLadmin]
Server=C:/mysql/bin/mysqld-nt.exe
user=root
password=azerty

Can anyone help me?

Try: c:\mysql\bin\mysql.exe -uroot -p

Then you will be prompted twice for your password...
I hope you didn't post your password here, and swapped it with a fake password...
It would be a huge security flaw if you had...
In the future, avoid doing that =)

I am only prompted for a password once and ... still 'Access denied'.
I have to start ASAP with DW but I cannot begin until this problem is solved.

My mistake, it only prompts once...

Try omitting the -p altogether.
Perhaps you don't have a password set on the root account.

Try: c:\mysql\bin\mysql.exe -uroot

I have now the solution:
I don't think you've created a user. Try logging on as root with no password (this is the default) setting. If you can log on as root with no password, you can change it by doing this:

Code:
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
To make another user read this: dev.mysql.com.

i've experienced da same problem once i change my username and my password. When i reinstalled mysql, i jus use root as da username with no password because i dunt want to face da same problem when i try to log in mysql in da future. i know it is not secure but how can i guarantee that once i update the user and da password, i wont face any problem to log in mysql?
