1) Adprep /forestprep as a minimum on the root DC in the Forest - if this is R2 you're adding then use ADPREP off the 2nd CD from R2 under CMPONENTS\R2\ADPREP.
2) Wouldn't hurt to run adprep /domainprep either.
3) Point the new server to the root domain's DNS for now until it's up and running. Add DNS to the new server to host for that domain.
That should get you started. Any additional issues may be due to your configuration there and can be addressed as needed.
