The global
remote
browse
sync
option specifies that Samba should synchronize its browse lists with local master browsers in other subnets. However, the synchronization can occur only with other Samba servers, and not with Windows computers. For example, if your Samba server was a master browser on the subnet 192.168.235, and Samba local master browsers existed on other subnets at 192.168.234.92 and 192.168.236.2, you could specify the following:
remote browse sync = 192.168.234.92 192.168.236.2
The Samba server would then directly contact the other machines on the address list and synchronize browse lists. You can also say:
remote browse sync = 192.168.234.255 192.168.236.255
This forces Samba to broadcast queries to determine the IP addresses of the local master browser on each subnet, with which it will then synchronize browse lists. This only works, however, if your router doesn't block directed broadcast requests ending in 255.
