Resolve Netbios name in Ubuntu

Edit /etc/nsswitch.conf and modify the line that shows something about hosts:

hosts:          files wins mdns4_minimal [NOTFOUND=return] dns mdns4 

Install winbind:

sudo aptitude install winbind

For system with more than one network and with WINS server up and running, edit /etc/samba/smb.conf, like:

wins server = [ip_of_wins_server_here]
name resolve order = lmhosts host wins bcast
wins proxy = yes
