samba - May 2007 - BDC keeps taking over and not allowing logins from NT PDC

Hello, thanks for looking over my ramblings...

We have an NT4 PDC with and NT4 BDC on 192.168.132.X, these boxes are
very very old and overloaded.  I am trying to replace them with a nice
shinny new Samba box.  My problem is that while I am trying to test it
out to make sure it plays nice it keeps winning the elections.

I find this weird as I have set the box to domain master = no and turned
the os level and announce values to really low values.

When it does win no one can login to the domain (and therefore their
workstations) and I have to stop samba to get users back logging in and
able to work.

I joined it to the domain via:
net rpc join -S [NT netbios name or IP] -UAdministrator%password

I got BDC rights and ran:
# net rpc vampire -S [NT netbios name or IP] -W [domainname]
-UAdministrator%password

About the time that users reported login problems I got lots of copies
of 
[2007/05/11 08:01:14, 0] lib/util_sock.c:get_peer_addr(1225)
  getpeername failed. Error was Transport endpoint is not connected
in /var/log/log.smbd

To add further complexity the samba box is on a 10. address while the
PDC and BDC are on 192.168. addresses.  Is this a problem?

Any ideas why it is winning the election, why users cannot login to
their systems, is my switch to a different address space a problem?

Thanks!
