Hello, I use samba 3.0.22 on my two PDCs. On both domains I see in windows network neighbourhood workgroups from long long time ago. E. g. when I use a computer with a workgroup of any name and samba discovers it, then its shown in that list. The workgroup stays there forever. But computer inside workgroups are removed from that list if samba can`t discover them any more. Any idea what could be wrong and how I can cleanup this?
