That I know WINS only resolve IPs to netbios names it is not responsible 
for "browsing", but it registers with the names the record types of the 
machines that it knows about (this is part of netbios), answering who 
acts as what in the network (in that case, who is the LMB and has the 
browse list). The machine that holds the list of "available" machines of 
its network segment is the Local Master Browser of that segment.

Theres a chapter in TOSHARG called "Network Browsing" showing an example 
of a routed network using WINS.

Configured machines in one subnet and a couple of machines in another?
Hmm. A network with a half of machines using WINS and a half not can 
show that behavior.

The Local Master Browsers in each segment of the domain search for a 
Domain Master Browser and ask to sync the lists. Have you sure that the 
machines that are acting as LMBs in each segment are doing this? That 
they can find the DMB and ask to sync the browse list? Maybe one of them 
isnt doing that, maybe you excluded an LMB of using the WINS server and 
its not finding the DMB?

As above, is that machine using WINS and the WINS server knows who is 
the DMB?
