samba - Jul 1998 - If WAN is broken I have a problem with local connect

We have two subnets with two samba servers (div0 - 150.10.10.1 and div8 -
150.18.18.1 ).
If I break the connection between subnets, clients belong to div8 cannot connect
locally.
All clients have set up wins server to 150.10.10.1 ( div0 ) .

If subnets are connect, all is ok ( connecting, browsing).
We are using samba 1.9.18p7.

smb.conf in div0 is
[global]
 workgroup = LANGROUP
 domain logons = yes
 logon script = netlogon.bat
 wins support = yes
 domain master = yes
 local master = yes
 preferred master = yes
 os level = 65

smb.conf in div8 is
[global]
 workgroup = LANGROUP
 wins support = no
 wins server = 150.10.10.1
 domain master = no
 local master = yes
 preferred master = yes
 os level = 65
 domain logons = yes
 logon script = netlogon.bat
