WINS - any way to force it to always reply via DNS

[Nathan Neulinger]

Two questions:

1) Is there any way to get nmbd to always reply and do it's lookup using a 
DNS query?

2) Is it possible to turn OFF dns caching in NMBD?

Here is an example of two queries from the log:

----------------------------------

Stooges does not have a nmbd or smbd running on it, but I do want it to 
resolve.

I have had odd behavior with this, where nmbd doesn't always seem to 
work. In one case, when I brought up the nmbd on a ethernet segment, it 
made all the PC's on that segment unable to browse the network at all.

Our setup:

Multiple subnets. All the subnets are forwarding broadcasts to one 
specific host that is running an nmbd.

There are lots of machines on the network out of our control, so it is 
likely that there will be other nmbds and NT stations, etc. I'd like to 
be able to override all of them and force our central server to be the 
master server.

Any ideas?
