These guidelines can be applied to a Slackware 13.x. The tests were carried out on several local networks, in particular a "promiscuous lan" with a Windows 200x domain server, 70 PCs with XP/Vista, some Slackware/Linux, 20 iMac Leopard.
Seems that, in recent versions of samba, with Konqueror or Dolphin we cannot correctly browse the Windows network, we get only workgroups names but not PCs names. Also command "findsmb" not works, sometime returns 0.0.0.0 as IP, other times remains waiting for long time and returns only a few names. The problem seems exist also in some installations of Slackware 12.x.
Why this? Here are some tests:
smbclient 2358 root 9u IPv4 173611 0t0 TCP 192.168.0.210:49569->hit-nxdomain.opendns.com:netbios-ssn (SYN_SENT)
kio_smb 2159 root 18u IPv4 12060 0t0 TCP localhost:40561->localhost:netbios-ssn (ESTABLISHED) kio_smb 2159 root 19u IPv4 12789 0t0 TCP localhost:35236->localhost:microsoft-ds (ESTABLISHED
In default smb.conf (smb.conf-sample) there is the correct line that inhibits dnslookup in names resolution but this line seems not sufficient.
dns proxy = no
name resolve order = wins lmhosts bcast host
