samba - Jun 2008 - 'remote browse sync

Is 'remote browse sync' only for syncing browser lists between SAMBA
systems.   I currently have 'remote browse sync' pointed at a W2K system
(browse-master) on another subnet and I see from the nmdb.log that a request was
received from that system for ' ...process_name_query_request( ...'  
and then   '... Sending backup list for ...'.

But the Browse lists never get synced, why ?

Thanks
