problem with lan browser in kde3.2.2 and suse 9.1

Folks, I just installed Suse 9.1 and with kde3.2.1 and kde 3.2.2 the lan browser does not work at all. smb:/ in Konqueror says something like internal error (Interner Fehler Bitte senden Sie einen ausführlichen Problembericht an http://bugs.kde.org Unbekannte Fehlerbedingung in stat: Das Netzwerk ist nicht erreichbar) and lan:/ says something like "internal error". (Protokoll wird nicht unterstützt lan). The lisa setup in the KDE control center is missing. Setting up Samba client in Yast does not help. Obviously I did somethig wrong during the installation or I forgot something. Any idea how to fix that is appreciated ! many thanks Chris
