Changed DC IP address, still wrong in DNS

Hi
I've been banging my head for a few hours on this and can't seem to correct it. Here's what's going on:
We have 2 domains in our forest. The DC with the problem is part of the child domain. It's IP changed from a 10.90.0.x to 10.238.0.x static IP.
I noticed some replication problems with the Replication Status Tool and what I've found is a DNS problem between the Parent and Child DNS servers.
If I do an nslookup on the cfc5a4e4-53ea-4232-b66e-41d6cc681cb3._msdcs.xxx.net record in the child domain DNS server, it resolves to the new IP address. If I do it on the parent domain DNS server, it resolves to the old IP address.
I've tried deleting that msdcs record in both sets of DNS servers and restarting NETLOGON, but within a few minutes, the parent gives the old IP address again and stops replication from happening.
Is there some way to scrub the DNS servers of any trace of that old IP address? Is there something on the DC itself that could be giving the wrong IP to the DNS servers?
Thanks for any suggestions anyone has

Hi Spencer,
After changing the ip addreess of the DC, have you run the following commands?
 ipconfig /flushdns
 ipconfig /registerdns

This has nothing to do with the problem. 
The record is properly registering locally, the issue is with the zone being properly replicated to the parent.  I suspect that you have (Or had) to wait for the zone to be replicated up to the parent.  Depending on the zone transfer schedule it
can take time.  My guess is everything is now working correctly.
