The two forward zones were set up by the AD installation
wizard and both are required.
For your new DC/DNS server, point the DNS settings in
TCPIP at the existing server, install active directory
creating another DC in the domain, then install DNS and
create the two AD integrated forward zones with the same
names as the existing ones on the first server. The zones
will then te. Updates to the zones on either
server will be ted to the other server. Create
backward lookup zone(s) in a similar manner.
