Internetworking browsing problem

[Andrei]

Hello all!
We have a network with about 50 computers. One of them is a Linux 2.0.31,
the rest are Windows95. I tried to make the Linux PC to be a router, so I
can split the network. So I put two NE200 cards on Linux and asigned two
IP addr : 
eth0 192.168.18.1 netmask 255.255.255.0
eth1 192.168.19.1 netmask 255.255.255.0
It worked OK, but we have a problem with Samba.(1.9.7p4). If I am browsing
the Network Neiborhood I am only seeing the workgroups from one network
and the server. The "find computer" from Windows95 reaches the computer
from the other network pretty fast. When I make a double click it show the
shares on that computer. The trouble is when I click "up one level". After
a couple of seconds it says "Qualite is not accesible" (Qualite is the
name of workgroup).
The log.nmb file keep repeating this message:

Name query from 192.168.19.9 for name FDS<0x1b>
Search for QUALITE(1b) - types 0x20 0x0 only: name not found

For the computer (TOM) in that workgroup (qualite) it says:

Name query from 192.168.19.9 for name TOM<0x20>
Search for TOM(20) - found with DNS: 192.168.18.101

I have the following global section in smb.conf:

   workgroup = servers
   interfaces = 192.168.18.1/24 192.168.19.1/24
   dead time = 30
   debug level = 3
   wins support = yes
   domain master = yes
   preferred master = yes
   os level = 255
   domain controller = yes

The Windows95 computers are configured also to point to samba wins server.
The wins.dat contains: 
.....
QUALITE#1e 880415108 255.255.255.255 ffe0R
QUALITE#00 880415108 255.255.255.255 ffe0R

TOM#20 880415109 192.168.18.42 60R

The browse.dat contains:
