What kind of DNS Problem is this and how bad is it?

I was testing some group policies, and tried to run the group policy results wizard in GPMC against a pc and got

the following:

RPC Server is unavailable.

I read and used some steps in this article:
http://technet.microsoft.com/en-us/magazine/cc138001.aspx. Good article but didn't help me.

On our primary DC, which runs Windows 2k sp4, I ran repadmin /showreps and all the replication came back ok.

I also ran the following with the results below:

dcdiag
Skipping all tests, because server SERVER1 is
not responding to directory service requests

dcdiag /test:connectivity
Starting test: Connectivity
SERVER1's server GUID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name (3bdc1b6f-776e-4652-9fe8-518e4515860d._msdcs.domain.name)
couldn't be resolved, the server name (SERVER1) resolved to the IP address
(192.168.*.*) and was pingable. Check that the IP address is registered correctly with
the DNS server.
......................... <SERVER1> failed test Connectivity

Our Second DC is running Win2003 R2 SP2. Ran DCDIAG on this domain controller, SERVER2

dcdiag /test:dns
Running enterprise tests on : DOMAIN.NAME
Starting test: DNS
Test results for domain controllers:

DC: SERVER2.DOMAIN.NAME
Domain: DOMAIN.NAME

TEST: Basic (Basc)
Warning: adapter [00000003] Intel(R) PRO/1000 MT Network Connection has invalid DNS server:

TEST: Forwarders/Root hints (Forw)
Error: Root hints list has invalid root hint server: l.root-servers.net. (198.32.64.12)

TEST: Delegations (Del)
Error: DNS server: SERVER3.DOMAIN.NAME. IP:192.168.SERVER3.IPADDR [Broken delegated domain SERVER3.ic.internal.]

Summary of test results for DNS servers used by the above domain controllers:
