Problems using passwords

[Laura Quattrocchi]

Hello,
i have installed samba on a linux 1.3.45 box and i have a problem.
This is the output of the smbclient -L dns:

Added interface ip=195.32.68.130 bcast=195.32.68.191 nmask=255.255.255.192
Server time is Mon Nov 10 09:25:37 1997
Timezone is UTC+1.0
Domain=[EOS] OS=[Unix] Server=[Samba 1.9.17p4]
connected as guest security=share
SMBtconX failed. ERRSRV - ERRbadpw (Bad password - name/password pair in a
Tree
Connect or Session Setup are invalid.)
Perhaps you are using the wrong sharename, username or password?
Some servers insist that these be in uppercase 

and this is the message error in the log file:

bind failed on port 139 socket_addr=0 (Address already in use)
Thanks to anyone who help me.
Laura.
