BIND 9.2.4rc8 Multithreading on Win32

[Vinny Abello]

I've been reading that threading is enabled by default on certain platforms 
with the newer BIND 9 versions and you can also manually enable it when 
compiling it. However, what about the Win32 binary package available from 
ISC? Is it enabled by default? If not, how do you enable it? Is this 
related to the the -n option?

I have three servers running BIND. One has two processors with 
hyperthreading (and BIND correctly identifies 4 CPU's in the event log when 
starting). On the other two servers there is only a single processor and 
BIND reflects that in the event log. If I start named.exe from the command 
line with -f -n4 it will show 4 processors in the event log. If I modify 
the image path in the registry to do just -n4 and start it, it only shows 1 
CPU. Is this possibly a bug in named or at least the Win32 version? Does it 
require the -f to listen to the -n switch making it only useful when not 
running as a service?

More importantly, am I even barking up the right tree doing this? Is this 
how you "enable" threading on Win32? Thanks in advance for any help, advice 
and/or answers!
