This option enables a couple of enhancements to cross-subnet browse propagation that have been added in Samba but which are not standard in Microsoft implementations. The first enhancement to browse propagation consists of a regular wildcard query to a Samba WINS server for all Domain Master Browsers, followed by a browse synchronization with each of the returned DMBs. The second enhancement consists of a regular randomised browse synchronization with all currently known DMBs. You may wish to disable this option if you have a problem with empty workgroups not disappearing from browse lists. Due to the restrictions of the browse protocols these enhancements can cause a empty workgroup to stay around forever which can be annoying. In general you should leave this option enabled as it makes cross-subnet browse propagation much more reliable. yes
