This WINS problem is baffling. I have built Samba from the source and the make install did not seem to put the libnss_wins.so.2 anywhere. Here is the ./configure command I used. Perhaps someone can enlighten me ./configure --prefix=/usr/local/samba --with-configdir=/etc/samba --with-privatedir=/etc/samba/private --with-piddir=/var/samba --with-lockdir=/var/samba/locks --with-logfilebase=/var/samba/logs --with-acl-support. I am running Debian Sarge release and I have the following development libraries installed: libpam0g-dev, libldap2-dev, and libnss-dev. I don't need ADS support. Something is going wrong but no errors are being thrown on the screen or in the syslog. WINS resolution is totally broken. I have the correct settings in nsswitch.conf. What else could I be missing? What further info do you need from me?
