My ISPConfig keeps stopping at the mySQL login

;
Code:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
ERROR: The provided MySQL password is wrong! The installation routine stops here!
Should my mySQL user be "server1" since that is the subdomain name for this computer?
I don't recall setting a user name specific to MySQL when Ioaded it. I did write down the passwords, keys, passes, and challenges so I am sure I have that part correct.
I enetered localhost for MySQL server: and root for MySQL user;. When I log into the console as root it is shows as [root@server1].

p.s. can I use #mysqladmin -u root password mypassword
to reset the password just in case...
