           DC3               PASS WARN PASS PASS PASS PASS n/a  

How do I correct the warning?

Answer 1

Talked to Dell support.
Was told the problem is a new interface that allows the iDRAC to be accessed through an USB port.
I decided not to use the new interface that allows the iDRAC to be accessed through an USB port. I went into Network & Internet Settings, Change adapter options, selected the Remote NDIS Compatible Device and disable it.
The disable did not remove all messages like Warning: Delegation of DNS server DC2.domain. is broken on IP:fde1:53ba:e9a0:de11:906e:5a09:5d53:ed19
Selected iDrac Settings, Management USB Settings, Disable USB Managment Port

Warning

Additional information

Warning: Adapter <adapter name> has dynamic IP address

Static IP addresses are recommended for all DNS servers.

Warning: Adapter <adapter name> has invalid DNS server: <name> <IP address>

DNS server may not be reachable.

Warning: No DNS RPC connectivity (error or non Microsoft DNS server is running)

Disregard this warning if the DNS server is a BIND or other non-Microsoft DNS server.

Warning: The Active Directory zone on this DC/DNS server was not found

N/A

Warning: Root zone on this DC/DNS server was found

How do I identify which of the number of causes listed above is causing a dcdiag warning?

This may be due to when the DNS was bought up there was a dynamic IP Address. Maybe this is a matter of clearing stored DNS errors

Answer 3

ipconfig /flushdns, ipconfig /registerdns, restart the netlogon service did not solve the problem.

I will try uninstalling DNS and reinstalling.

Answer 4

Uninstalling and reinstalling DNS did not work.
