DNS - Help Finding \ Deleting Old DC Records?

I need help in locating an old DNS record for a DC that was decommissioned last week.


I have looked through DNS (forward and reverse zones, all sub directories) and can not find a record of this server's name or IP address.

Yet I know there is an old record present as I receive the warning below when running netdiag:

DNS test . . . . . . . . . . . . . : Passed
       [WARNING] The DNS entries for this DC cannot be verified right now on DNS
 server xx.xx.xx.100, ERROR_TIMEOUT.
    PASS - All the DNS entries for DC are registered on DNS server xx.xx.xx.101
' and other DCs also have some of the names registered.

I did have a few issues demoting the DC, DNSCMD was used to delete the records.

Obviously, a record from this server must still be present somewhere due to the warning above.

I could use some direction in regards to tracking down whatever records that remain for this demoted server – any help would be appreciated.

Right click on the zone name and open properties... name servers tab. if it is still there, remove it.

Man, I wish it were that simple.  That entry had already been removed - all listed name servers are legit DC's.

Would be nice if I could simply right click on the root of the forward and reverse lookup zones and search for the DC name or IP.

Is there a tool that can point to DNS and perform similar searches?  

How do you find an old record that is still participating on the domain?

Run IPCONFIG /all and you'll probably see that DNS server is still listed in the NIC config.
Netdiag is a local computer test, so all info it uses it reads from the local machine.

Remove the DNS server entry from your NIC and you should be fine.

If may be cached if you can see the record.  On your testing from do an ipconfig /flushdns to dump the dns cache .  Also go to your dns management MMC and clear the cached lookups for each DNS server.  Then try again.

I’ve spent so much time removing old DNS records in practically every area of DNS, only to have left the old address as a secondary DNS server on the nic config.

So I was not an old record, but rather the configuration on the server’s nic.

Good call Sulimanw, sorry for taking up everyones time.

This, apparently, is not my day.  I accepted the wrong solution - the correct solution came from smckeown777.  My appologies.

Man, I was hoping to correct this before you noticed.  I'm sure there is a way to correct this - I'll see what can be done.
No hassle...think you need to 'Request attention' and a mod will re-open the question for you...
