[Samba] Problem to have access samba in subnets

[Rogério Oliveira Naressi]

  Still I continue with a problem that I told these days in
the list, but now obtained to identify better. My server with
samba this functioning and my clients correctly makes access
normally, after some days my clients stops to deny access
samba. Only clients with IP in subnets off samba access samba
ok, clients with IP in other subnets not access samba.
  After I restart smbd e nmbd, clients start to have access
the samba again.
  I have Samba 2.2.3a-12.3 for Debian how PDC in network
with 4 subnets, this runing how Wins Server.

  Help, please !!!

  Rogério.
