samba - Jan 2005 - multi-homed server: trouble hiding private interfaces

How can I effectively and completely hide private interfaces on my Linux 
Samba servers?  (PDC and file server)

Even when I use the "interfaces" option and even "bind interfaces
only",
  "net lookup dc" still returns IP addresses from the private 
interfaces, and for that matter another machine that is not even running 
Samba (once was, no longer).  Seems like the info is cached somewhere I 
don't know of.  I'm running Samba 3.0.7.

My PDC's interfaces are as follows (eth0 is down and unused):

eth1: 192.168.10.193/24
eth1:0: 192.168.10.230
eth2: 192.168.20.2/24

Another machine that backs up the PDC - normally not running samba at 
all, but takes over the .230 address if the PDC goes down has:

eth1: 192.168.10.194/24
eth2: 192.168.20.1/24

When I type net lookup dc, here's what I see:
192.168.10.230
192.168.10.193
192.168.10.194
192.168.20.1
192.168.20.2

Ideally I'd like to have it show just the .230 address.  Beats me where 
all the others are coming from.  I've tried:

interfaces = 192.168.10.0/255.255.255.0 127.0.0.1
bind interfaces only = Yes
  - seems to actually hose things up; clients say a DC is not available

interfaces = 192.168.10.230 127.0.0.1
bind interfaces only = Yes
  - works ok but I still see output from net lookup as above and clients 
trying to talk to the .20 network

interfaces = eth1* 127.0.0.1
bind interfaces only = Yes
  - same result as #2

Thanks in advance for any help.

Figured this one out too - /var/cache/samba was the answer (in 
particular, wins.dat and gencache.tdb).  I stopped samba, removed the 
files and restarted.  Now net lookup dc returns the single IP address I 
wanted.

Sorry for the wasted bandwidth...
