Additional Tree DNS Question

[Guest]

I currently have one AD domain (headquarters.company1.com) and I need to add
an additional tree complete with different namespace
(headquarters.company2.com).

How should I configure the DNS server that will reside on the DC in the new
tree, so that it can connect to the DNS server that resides in the existing
AD domain?

This was a slight problem with Win2k, you cannot forward the DNS servers to
each other to allow resolution of both domains from each DNS server, this
will set up a DNS loop. The best you can do is have a secondary zone for the
other domain on each DNS server.
This was solved in Win2k3 by adding support for Stub zones and conditional
forwarders.

Thanks for your response.

Should I switch off forwarding, and create an additional name server in each
domain?

Forward all DNS servers to your ISP, then on the new DNS server for the new
tree, create a secondary zone for the forest root DNS zone on it.
After the new domain tree is set up create a secondary zone for the new
domain tree on the forest root DNS server.

Or- alternately, you can let the forest root DNS server host the zones for
both domain trees. Unfortunately the zone will not replicate through AD to
the DC for the new domain tree in Win2k. This is why you need to use
secondary zones if you want each domain tree on its own DNS server.
Win2k3 does a much better job in this situation because Win2k3 supports
forest wide DNS replication, conditional forwarders, and stub zones.

Hello Kevin

I followed your instructions with regards creating secondary zones, and have
made some headway, however, I'm now getting an error, which says: The DNS
server encountered an error while attempting to load the zone. The transfer
of zone data from the master server failed. ANY IDEAS

On the properties of the Primary zone, Zone transfers tab, set allow zone
transfers to the IP of the secondary.
