I would recommend that you set up your new domain on an isolated
network
and get it working properly on its own subnet using its own DNS and DHCP.
When that all works, set up a virtual machine (not the DC) as a router
between that subnet and your existing physicalLAN. You will need extra
routing so that the existingLANknows where the new subnet is and how to
reach it. You will also need to set up your DNS on the new domain to
forward
to a DNS server which can resolve public URLs.- Hide quoted text -

Working like a charm so far.. All i had to do was add a static route
in my router to the RAS server on my virtual network.. and on that RAS
server have a secondary nic with an ip address in the real domain..
all machines in the virtual realm have the gateway set to the RAS
server address..

Now onto secondary thing.. DNS.. what is the usual way to hack this
one.. should i just put for the secondary dns addresses on every
machine in the Virtual Network, the dns of the real network? Or can I
just do a forward from within the DNS manager (right click server
name.. forwards tab.. enter ip address of the opposite dns servers?)
on the Virtual network and the same on the real.. i think this one
would be simpler?

I can only ping by ip as of now naturally.

UPDATE: Tried adding the real domains ip addresses to the forwarders
tab, recycled things, waited, i still cant ping them by name as of
now. Actually.. i can ping the other domain.. but only if i add the
domain suffix.. ie: ping serverA.domain.local I'm guessing i can tweak
the settings to fix this.. hoping i dont need to add this suffix to
every machine in the virtual realm. This ping with the suffix actually
works without doing anything to DNS on either side too.

Have you tried simply setting the new DNS to forward all requests to the
existing DNS on the physical network? Another solution would be to make the
new DNS a secondary for the original DNS so that it had a local copy.- Hide quoted text -

I think at first i did try the forwarding option, just adding the ips,
but...

I fixed the problem.. on the server properties for each dns server on
each side.. i had to add a new dns domain for the opposite domain (not
just add the ip), then the dns server(s) ip addresses.. once i did
this.. they started communicating from either side.. but only by
FQDN..

I cant run DHCP on the virtual LAN, or so i think, because if i do..
it may give out those .227.x addresses to the .100.x machines by
mistake (hence I think, naturally, the test domain machine names dont
auto get put into DNS, with their A records).. so everything is manual
on the virtual side.. meaning now to ping either side.. i use the
FQDN, but name nonetheless (\\server.domain.local)- Hide quoted text -

Actually I have a new problem.. for some reason my virtual lan cannot
access the internet.. I cant even ping via internet ip addresses.. so
i dont think it is a dns issue, more likely a routing issue.
