Maverick 10.10, but I think should be the same on 10.04:

$ ls /etc/samba
dhcp.conf  gdbcommands  smb.conf  smb.conf~  smb.conf.ucf-dist
$ locate smbpasswd
/usr/bin/smbpasswd
/usr/sbin/mksmbpasswd
/usr/share/doc/samba-doc/htmldocs/manpages/smbpasswd.5.html
/usr/share/doc/samba-doc/htmldocs/manpages/smbpasswd.8.html
/usr/share/man/man5/smbpasswd.5.gz
/usr/share/man/man8/mksmbpasswd.8.gz
/usr/share/man/man8/smbpasswd.8.gz
/var/backups/smbpasswd.bak

Is nmbd running?

$ service nmbd status

should appear as:
$ service nmbd status
nmbd start/running, process <pid>


Are they both using the same workgroup name?
