I cannot find an (A) record) in DNS...

When I run nslookup against a machine name on the DNS server. it gives me the wrong/old IP address. The machine isn't on our local network anymore and I need to rid the A record from DNS.

mmc for dns
Right click the server
nslookup
I type the computer name and the OLD Ip address shows up.

mmc for DNS
DNS server Forward lookup zone
domain.com
there are no A records for the name that I am looking for.

What gives? tombstone?

"The machine isn't on our local network anymore and I need to rid the A record from DNS"  Are you sure that your LOCAL DNS server is giving you this resolution?

type

NSLOOKUP machinename <enter>

If the response says something like:  

Non-authoritative answer:        <--------  This line means that an upstream DNS server has this record and provided the reply.  
Name:    www.yahoo-ht2.akadns.net
Address:  xxx.xx.xxx.xxx
Aliases:  www.yahoo.com


If you get an non-authoritative answer, it means that your local DNS servers are not resolving this...but an upsteam DNS server is...  You would need to correct the DNS entry on the upstream DNS server.

This machine is local and there is only one DNS server.

The answer for nslookup is from the local DNS server, not an upstream one (which would be the ISP).

Thanks

In the DNS console....  VIEW --> check off ADVANCED

You can look for the record in CHACHED Lookups....

If you right click CACHED lookups, you can delete ...

What IP address is returned?

What name is returned?

Default Server:  domain.com
Address:  xxx.x.x.xx

> ccpidc1
Server:  domain.com
Address:  xxx.x.x.xx

Name:    domain.com
Address:  xxx.x.xxx.xxx

>  xxx.x.xxx.xxx
Server:  domain.com
Address:  xxx.x.x.xx

Name:    domain.com
Address:   xxx.x.xxx.xxx


CCP is a child domain. CCPIDC1 is the domain controller for that domain.

NJComputerNetworksCommented:
So, CCPIDC1 is the computer in question.  This is the computer that should not appear in your DNS because it does not exist?

Was this server a domain controller?  If it was, did you demote and remove the domain controller (or entire domain) before turning the computer off?   if not, you need to do this...  or you need to run a few recovery steps...

I found the problem.

DNS forward lookup zone was forwarding to WINS whcih had the wrong record because it's not dynamic like DNS.

Thanks for your help
