We have Domain at our corporate office that is the parent domain, lets say
corp.com. Then we have a child domain, childdomain.corp.com. They each have
their own Dns server. I want to beable to ping computers in the child domain
by using the computer name. I think I can use dns forwarding to do this. My
question is will there be any preformance issue for user in the parent
domain. Right now forwarding is setup to first forward to the parent
domain's DNS server then to our ISP dns server. I want to set it up like
this
parent domain's DNS server then childdomains dns server then to our ISP dns
server. Will this cause performance issues? I am running Win 2003 domain.

I think you are making this more difficult than it needs to be.
You simply need to create a delegation record for childdomain.corp.com in
corp.com zone.

You using delegation for parent to child zone relationships.
You use forwarding for child to parent zone relationships.

As was stated in earlier post, just delegate the zones to the
children domains and all will be well for users of the parent
domain DNS. If you are purely W2k3 AD, then leverage the
_msdcs being a forestwide application partition and let is
reside on the children's DNS. This will allow client of those
DNS servers to access any name in the forest, while the
delegations in the parent DNS will let clients of the parent
DNS server find any name.

However, there are implications in what you have said that
seem to indicate you have deeper issues.

but I had thought you were talking about the Forwarders

defined on the parent DNS server - so you would not forward
to themselves.
I just want to make certain you are not speaking about the
DNS servers defined in the Tcp/Ip config.

At any rate, remember that no DNS server should forward to
the outside unless it is able to resolve any name in the forest,
and that you must not set up a forwarding cycles in how you
have defined who forwards to whom.
