Browsing problems

[Matt Claridge]

Hi, I'm hoping someone can help with this - we're having some spurious 
Win95/98 browsing problems and although I'm continuing to experiement 
with things, I'm really not sure whats causing the problem. I've read 
the docs and various Samba books, but I'm no closer to a solution at the 
moment.

We currently have three subnets and five workgroups in our network, 
arranged like this:

Subnet 1:
workgroup 1
workgroup 2
workgroup 3
workgroup 4

Subnet 2:
workgroup 5

Subnet 3:
workgroup 1

So workgroup 1 spans two subnets.
Subnet 1 is the main subnet. Subnet 3 routes through subnet 2 to reach 
subnet 1 (does that make sense worded like that???)

Workgroup 1 - Samba LMB, Win9x workstations.
Workgroup 2 - Samba WINS server, Samba LMB, plus two other Samba print 
servers, configured NOT to be browse masters.
Workgroup 3 - Samba DMB (controlling domain logons.
Workgroup 4 - Win2000 server(!!!), Win9x workstations.
Workgroup 5 - Samba LMB, Win9x workstations.

I hope that makes sense! SO, here's the problem:
WIndows clients in subnet 1/workgroup 1 can browse all five workgroups. 
The only problem they have is not seeing the machines on subnet 3 (same 
workgroup).
The Win200 server in workgroup 4 can only browse its own workgroup.
WIndows clients in subnet 2/workgroup 5 can browse all workgroups EXCEPT 
workgroup 1 (this results in a "share name not found" error)
WIndows clients in subnet 3/workgroup 1 can only browse machines on that 
subnet.

smbclient -L localhost -U% on any samba machine returns a correct list 
of servers and master browsers.

All Samba servers and Windows clients are configured to use the WINS 
server and there's no problem accessing shares either by mapping drives 
or using net use in DOS. I'm not sure of two things though - maybe the 
Win2000 server is interfering with the Samba servers? and maybe I 
misunderstood the Samba browsing docs :o)

If anyone has any pointers for this I'd be most grateful - I know 
browsing can be a pain in the backside, and it isn't exactly essential, 
but it would be nice if I could get this working.

Many thanks in advance
