domain controller with integrated DNS still giving out old ip
Posted on 2011-05-11
We just moved our main web server to a different set of IPs. The DNS servers in the DMZ are linux based and are giving out the correct new IPs. Internally, we use integrated active directory DNS on all of our domain controllers. The internal domain name is different from the public domain.
After the migration, three of our domain controllers are giving out the new IPs, (checked with nslookup for each server), but the primary DC insists on giving out the old IPs. We have rebooted it several times and flushed dns several times. I finally added the new IPs to the hosts file and rebooted. It still gives out the old IPs. We have disabled WINS on all domain controllers. The lmhosts file is empty.
Where else could these old IPs be coming from?
