rerunning checkconfig doesn't reset admin account

[Mads Rasmussen]

In the manual it says that rerunning the checkconfig script resets the 
admin account, but it doen't for me.

Sorry for the lame question, I know what password I chose for the admin 
account (I'm not that lame) but what is the login?

I have tried "admin", "administrator" and other wild guesses, but it 
keeps failing.

So I wanted to rerun the checkconfig script to reset, which it doesn't.

How do I go about resolving this?

Regards,

Mads
