Deleted DNS Records Showing Back Up Again

I have a Windows 2003 domain. I have a server that is multi-homed.
One of my colleagues configured one of the NICs to have an internal private
IP address of 172.16.x.x which is our internal network and the other to have
a different private IP 192.168.250.x that goes to our new data domain. The
problem is, when he did this he left the check mark to register the DeDup
NIC in DNS when we only wanted the internal NIC registered. After
correcting the configuration the DeDup 192.168.250.x address keeps popping
back up in DNS which reeks a little bit of havoc with connectivity. We have
deleted the entry in DNS several times now from every DNS server but it
keeps popping back up the next day. Where should I be looking for this
address? Is it cached on one of the DC's and get's populated in again from
that or ???

Any help would be greatly appreciated -
Jon

If this is a DC that is multihomed that is a bad idea.
See if this helps:

In addition to Danny's link, please read my blog on Multihomed DCs. It
explains in full detail what is going on, why it's happening, and
additional steps you *may* need to take to alleviate it.

Replied privately.

Everyone that sent me a note about this thank you very much. It is NOT
a DC but the situation seems to have fixed itself. The entry hasn't shown
back up for a number of days now so I'm thinking it's taken of of in AD/DNS.

Thanks again -
Jon
