DNS entry gone - nslookup still shows there - baffled!!

[Mike]

Hello,

I have been trying to TS a problem whereas our clients are
not dynamically registering themselves in our AD-int DNS
zone. In doing this, I have changed the host name of a
client that is DHCP enabled after changing some client DNS
advanced settings.

My problem is, that I still received a reply of the same
IP when doing a ping to the old host name even though I
have changed the host name and rebooted. I have gone
through all of my forward and reverse zones and there is
absolutely no sign of the old host name, yet, I still get
a reply. I have flushed my local DNS several times and
tried the nslookup and ping from diff machines - same. An
nslookup reverse returns the correct IP.

Any suggestions?

What type of changes did you make?

Are the clients pointing only to the AD DNS server only?
Do you have a hosts file?

Only changes on the client - "register this connection's
address..."

No hosts file being used.

[mike]

yes - they are assigned the IPs of our two local DCs which
are running one AD-integrated zone.

Did you put in the DNS name of your AD domain in the field?

You can use DHCP to do this, too. Use option 015 DNS domain name.

Maybe it's a WINS entry or an LMHOST entry?

How are you pinging, by single name or FQDN?
