How to configure

[bhhyh]

Hi,good morning every one.
I configured a samba server on linux system,when I test the samba server by 'smbclient -U% -L localhost',the wrong message is :tree connect failded:ERRSRV-ERRbadpw(bad password - name/password pair in a Tree Connect or Session Setup are invalid).
On the other hand,when I visit the samba server by Win2000 professional client,I can see the icon of the machine which have installed samba server.but when I double clicked the icon , the wrong message is ;can not find the network path.I configured the [public] in /etc/samba/smb.conf.below is my configuration file,please tell me what's wrong with it and how to add a new user to smb database?
