Kevin-

Without making any changes, I noticed that I can ping by name across
domains; however, it needs to be fully qualified. Meaning if I want to ping
PC01 in domain abc.def.com, I can successfully ping PC01.abc.def.com, but I
cannot ping PC01. I don't know where to go with this one (will this
involved WINS?).

I've also noticed an inconsistency in the DNS settings on the new DC and
existing DC.

In the new DC, the only forwarder is the existing DC. The new DC's NIC has
its own IP and our gateway to the internet for that subnet as DNS servers.

For the existing DC, the forwarders are the gateway to the internet for that
subnet, a public DNS server for our ISP, and the new DC. The existing DC's
NIC has its own IP, its subnet's gateway to the internet, and the same ISP
public DNS server.

Which one is configured correctly???

Also, when using nslookup, how do you determine where the resolution
actually occurred (sort of like a trace)? I'm curious to see if requests
for external domains to our new DC are incorrectly being resolved through
our existing DC.

Thanks...getting close now!
