browser service

Hello friends!
We have 3 subnets in our network.
192.168.42.xxx
192.168.52.xxx
192.168.62.xxx
Routing is Ok , so I can ping the workstation
on every segment from any other workstation.
Active directory is not activated.
On the windows 2003 server ( on the segment 62)
is IsDomainMaster in the registry set as True
hoping that it will become the domain master browser collecting browser
lists from master
browsers on the other segments.
We are still viewing only the workstations on the segment we are on.
Is it possible to set up the whole network to see all workstations on all
segments , or it is impossible without active directory?
Thanks
.
