Hello,

     The attachment piece is the wireshark capture on the subnet 2 
network interface of the gateway.
     We could find at packet number 46 server list, in response to the 
winsgw2 request, contain only 3 entries but it reports 4 records in nmbd 
logs (see above).

     If I shut down server "RTRT", on subnet 2, it will never be removed 
from browse list on the two samba server even it's down state is 
detected by winsgw2.
[2011/06/08 18:14:05.803665,  3] 
nmbd/nmbd_serverlistdb.c:195(expire_servers)
   expire_old_servers: Removing timed out server RTRT
[2011/06/08 18:14:05.803938,  3] 
nmbd/nmbd_serverlistdb.c:423(write_browse_list)
   write_browse_list: Wrote browse list into file 
/var/cache/samba/browse.dat
Attachment winsgw2_sync_rowse_RTRT.pcap is showing sync after the 
timeout message in nmbd log file.
At packet number 29 winsgw2 say that it has only him in his subnet but 
browse.dat is still containing all the 5 lines (as above).
At packet number 54 winsgw say it has 3 server himself, winsgw2 and RTRT.
The browse.dat file is as above for winsgw.

     I don' t know where to search now, any one could give me any advice ?

    Thank you.

Best regard,
