How to set up having 2 Domains 2DCs and 2DNSs on one LAN for 1-2 weeks

I'm moving from one set of 10clients&1server to another set.
In the meantime I'm running all machines on one LAN.
What do I need in terms of DNS settings to make it work?
In particular, my W2012Essentials can't see its own domain.

Old:

mfk.atlas
sbs2003  at 192.168.1.2

new

ldm.local
win2012 at 192.168.1.215

I've put in a forwarder to win2012 for ldm.local in the DNS on sbs2003...
and a conditional forwarder for mfk.atlas to sbs2003 in the win2012 DNS.



ipconfig /all on w2012

you could set static ip addresses on the clients so they can only talk to the correct server, etc.

and a conditional forwarder for mfk.atlas to sbs2003 in the win2012 DNS."

This is what you need for cross-domain DNS queries to work.

Every domain controller in the mfk.atlas  domain  should have a conditional forwarder setup for the other domain to the other  AD domain's DNS server's and  Vice-Versa.

So that each  DC can ping the  other AD domain name.

This provides access to the other domain's  DNS names, for various uses.



It does not provide actual authentication access from a user or computer one AD domain to resources in the other ----   which requires trusts, a feature that requires Windows Standard edition or higher.     Which SBS and Essentials, definitely are not.
