Hello Ahmad,
That was my initial attempt. The issue I ran into was that the dnsmasq
settings on the Virtual Router seem to block the traffic that was required for
the machine to join the domain. I played around with the settings a little bit
and was able to get it to find the domain, so I would imagine that I could
tweak it some more to not be an issue. However, any changes I make on the
virtual router only last until it is restarted, so without a way to make those
permanent I have to circumvent it entirely. The blog post that Murali linked
for how to set up a network without DHCP and DNS seems like it was probably the
correct way to do it, but as far as I can tell would require me to start my
zone from scratch, so I am trying to avoid that if possible.
Thanks, David Ortiz
