another (yawn) subnet browsing problem

[Beau Atwater]

OK, I've read BROWSING.txt and NetBIOS.txt and I've been following the
list for almost a year.  Browsing only half works and I'm using
1.9.17p3.

Our network has many subnets but I'm concerned with only three.  Indeed,
it looks a lot like the example in browsing.txt.  Subnet A has the samba
server (domain master for Workgroup W and local master for subnet A) and
several NT workstations all on Workgroup W.  Subnet B has several NT
workstations on Workgroup W.  Subnet C has the WINS server, which is
also the PDC for a huge domain that I'm not part of.  The browse lists
for subnet B are OK:  they contain everyone from W on subnets A and B.  

However, subnet A only sees workstations from subnet A and the browse
list for the samba server (on A) contains only the subnet A NT boxes,
and other workgroup masters also on A.  If I use tcpdump or netcat I can
see lots of communication on subnet A to the WINS server on port 137. I
also see that every 12 minutes the local master of B sends a packet to
samba on A on port 138, which must be the browse list sync for subnet
B.  BUT, I never see the synchronization request sent back from samba on
A to the local master on B.

Other misc. info:
1) everyone has the same subnet mask and correct WINS server address.
2) no one is using lmhosts
3) log.nmb shows correct elections on subnet A and an initial query for
domain master to WINS
4) testparm says everything is ok
5) all tests passed in DIAGNOSIS.txt
6) we use a "0" based broadcast (XXX.YYY.ZZZ.0)
7) here is the relevant smb.conf:

  workgroup = W
  domain master = yes
  local master = yes
  preferred master = yes
  os level = 40
  wins server = XXX.XXX.YYY.YYZ
  wins proxy = yes
  password level = 3

I'd sure like to get this working.  I'm sure I'm doing something dumb so
I've been reluctant to post to this list.  Sorry for the barf.  Thanks
for any suggestions.
