I have a Windows Server 2003 machine that is our domain controller. It is the only domain controller (I know bad practice). It is having some hardware issues so I want to move the domain controller to a Windows Server 2012 machine. I ran the following
dcdiag command just to make sure the domain was healthy before migrating the DC:
Dcdiag /v /c /d /e /s:SERVER001 >c:\dcdiag.log
Looking through the log, all the tests passed except for the
VerifyEnterpriseReferences test. I am receiving the following:
Starting test: VerifyEnterpriseReferences The following problems were found while verifying various important DN references. Note, that these problems can be reported because of latency in replication. So follow up to resolve the following problems, only if the same problem is reported on all DCs for a given domain or if the problem persists after replication has had reasonable time to replicate changes.

AMPNT1 just happens to be an old Windows 2000 Server machine. A while back I had the DC functionality moved from it to the SERVER001 machine. I am guessing it did not get demoted properly.
Looking at the Q312862 article referenced above in the log file I noticed it is for recovering missing objects. I am thinking I don't need to recover the objects, but rather completely remove them. So with a little searching I found How to remove completely orphaned Domain Controller.
I was working through the steps and I am getting stuck on step 13. I am not seeing an entry for server AMPNT1. Here is what I am getting:
What might I be doing wrong? How do I go about fixing the
VerifyEnterpriseReferences failed test? Am I moving in the right direction? Does this need to be corrected before moving the DC functionality to the Windows Server 2012 machine?
You can see in the following screenshots AMPNT1 is not found in The Domain Controllers object of Active Directory Users and Computers nor under the Servers node of Active Directory Sites and Services:
