Name resolution on internal netwrok

I have a computer called spanky on my network. Spanky is a laptop that was unplugged from the network this past weekend. When spanky came back on the network, it is showing as a different name when using tracrt to it. for instance, when I tracert spanky I get:

Tracing route to spanky[172.16.40.250]
over a maximum of 30 hops:

1 <10 ms <10 ms <10 ms testdomainmovepc[172.16.40.250]

Now, we use AD servers for our DNS internally. It almost seems like a cache problem on our AD servers, as testdomainmovepc was listed in the DNS with the same IP address as spanky. But, testdomainpc is not anywhere on the network at this point.

Any ideas on how to make spanky look like spany?

First I would remove the testdomainmovepc record from your DNS. To my knowledge that is not a randomly generated name. Is that a name you have given to any of you computers? Are there any other entries in DNS thta shoudl not be there.

The computer you perfomed the tracert from, did you flush the dns cache on it? ipconfig /flushdns

You might also check your DHCP server on the DC, if you have one, to see if the problem is in that.
Did you also check your router (if you have one) to see if it has a running DHCP server ?

That worked, removing it from the reverse dns. How can I change the timestamp on when this is updated? It has been over a week on this. Can I make it a few hours or a day?
