DNS Setting for 2 active directory servers

I am tring to provide redundancy to our domin by installing another domain controller. We currently have a Windows 2003 DC that is functioning properly (as far as I can tell). I have added a Windows server 2008 R2 server, joined it to the domain, activated the DNS role, and then activated domain services. Everything seems to be OK - no error during install, active directory users and computers are visible; however it seems that the new domain controller is not discoverable on the network (maybe DNS issue?). I run dcdiag /test:registerindns /dnsdomain:FQDN /v and I get this:
Starting test: RegisterInDNS
This domain controller cannot register domain controller Locator DNS
records. This is because it cannot locate a DNS server authoritative for
the zone FQDN. This is due to one of the following:

name are not responding or contain incorrect delegation of the DNS zones;
2. The DNS server that this computer is configured with contains
incorrect root hints.
The list of such DNS servers might include the DNS servers with which
this computer is configured for name resolution and the DNS servers
responsible for the following zones: FQDN
Verify the correctness of the specified domain name and contact your
network/DNS administrator to fix the problem.
You can also manually add the records specified in the
I see some suggestions to fix the issue, but could really use a more basic/direct example of what needs to be done or a better way to determine the root of the problem. Any help is greatly appreciated.
