[ActiveDir] Authoritative Domain Problem

[Edwin]

I have my DC setup as a DHCP Server as well as a DNS Server.  I work for a company that has public DNS records (mycompany.net) that are used to reference servers that are accessed daily.  I setup the DC to use mycompany.net as the domain name and now I am having troubles resolving DNS for these daily accessed servers.  So for example, if I needed to access a server I would normally reference it by calling servername.mycompany.net.  I should have used a 3rd level domain for the DC but that is too late to argue about or change now.   Since I have Win2K3 as my DC I tried to do a domain rename.  As I started reading the documentation, I quickly learned that I could not do this because the client machines already on the DC are running Win2K Professional ( easy fix ), but more importantly the MS Exchange Server we have online would not support the domain name change.  Therefore, because of the Exchange server I could not risk performing this task a second time since the Exchange Server was just recently moved to this new domain in question and I received a lot of grief because of the migration process.   So here is my question.  Is it possible to have the DNS server of the DC forward an authoritative request to a public nameserver?  I have tried doing this by configuring the “Forwarders” tab under the DNS propertied without success.  The workaround being used right now is to change the DHCP server order by having the public nameservers listed first and then the DC DNS server listed last. This of course doesn’t sound like a good solution.   If forwarding is not an option, then is it possible for the internal DC DNS server to query the external public nameserver and then pull the data that it does not currently have?  If so, can you please lead me in the right direction?   I hope that I have made my question clear.  If anyone is able to help, I will be more than happy to answer any and all questions that I can.
