DHCP Mysteriously Unauthorized

Good day Experts. I'm a novice Administrator and this issue haunts me. I have a DC running Windows Server 2003. It runs DHCP and Active Directory. DHCP was mysteriously unauthorized, and the authorize option from the Action Tab is not present. I went into Active Directory and the following error message popped up:

Naming information cannot be located because:
The target principal name is incorrect.
Contact your system administrator to verify that your domain is properly configured and is currently online.

I tried running a dcpromo to remove/reinstalling Active Directory and but after following the steps in the wizard, the following error message popped up:

The operation failed because:
Managing the network session with rbgrdc.CFLSLU.COM
"Logon Failure: The target account name is incorect."

(rbgrdc.cflslu.com being another DC on the netwprk).

All the troubleshooting has been done while logged in as an enterprise admin. Not sure what my next step should be from here. Any assistance would be much appreciated.

Check your DNS. Are there any duplicated
records, both A and PTR ?
- Make sure you have one-to-one mapping between IP and host name for
all DC and affected servers.
- make sure all your SRV records are registered properly
