[Samba] Error messages when trying to access a share

[Fábio Soares]

Hi everyone!

Does anybody know what each of the error messages "ERRinvnetname" and
"ERRbadpw" mean?

The first one I get when I type my password after each of the
following commands:
smbclient -L localhost -U fabio    
//it only asks me for a password (I think it's to be my password)
smbclient -L localhost -N
//it doesn't ask a password. what/who is the username? 

The second one I get when I try this command:
smbclient -L localhost
//it does ask a password. but whatever password I type, the ERRbadpw
error message arises on my screen. Why?? where does samba take a
username for this password from?

my smb.conf file is attached. you might want to take a look at it.
