DNS server netlogon.dns file invalid entried

Hi all
I am running server 2003 ent edition domain.  My netdiag was failing over dns test with "DNS test . . . . . . . . . . . . . : Failed
       [FATAL] File \config\netlogon.dns contains invalid DNS entries.       [FA
TAL] File \config\netlogon.dns contains invalid DNS entries.       [FATAL] File
\config\netlogon.dns contains invalid DNS entries.       [FATAL] File \config\ne
tlogon.dns contains invalid DNS entries.    [FATAL] No DNS servers have the DNS
records for this DC registered.

I looked at this file and found that it takes lots of values of our OLD DOmain name.  Can I remove those entries or simply rename this file? if not whats the easist way to fix this issue.

Used the Domain Rename tool?

You might find you can get away with Find / Replace in the netlogon.dns file to correct the entries.

I backed up the copy of this netlogon.dns and removed all entries of our old domain name.  did ipconfig /flushdns, restarted dns and then ipconfig /registerdns.  Looked at the file and the old domain name came back.  I wonder where this file is getting the entries from, is it adsiedit??
Help plz

Nope, that would be too easy. Did you try replacing the entries with entries for the new domain? Or does it have duplicates in there?

I completly removed the entries of my old domain name.

As you said, I renamed the entries in netlogon.dns and now the DNS test in netdiag is passed and all NICS are properly registered.

Good stuff, glad it worked out :)
