OK, so I have something that got screwed up. Follow this - we have a root AD domain (Win 2012 R2). This has an AD-integrated sub-domain where all the actual users and hosts live, *and* a Standard Primary (non-AD) zone. Basically, the Primary zone is used for external hosts on the DMZ, etc.
On that DMZ, we have a IIS proxy that is dual homed. 1 NIC on the DMZ IP range, 1 NIC on the internal LAN IP range. Got all that? In the sub-domain, we have CNAMES that point to the hosts in the Primary zone. And it turns out, somehow an entry got created in the reverse lookup zone of the AD domain that points to a host on the primary zone (a PTR record got created with the internal IP of that IIS proxy, but apparently the host name was just typed it; we didn't browse to locate the host when it was created). So now, in the reverse lookup zone of the AD domain, I have an entry that says: "(same as parent folder)", the type is PTR, and the data is the name of a host in the Primary zone. I can delete it, and it comes back immediately. So: how can I get rid of this entry? This looks like a screwed up PTR record, but I just need it gone. It's not like I want to edit it, and point it somewhere. This whole reverse zone is for the Primary domain range, so there are no other PTR records there at all. Except for this now wrong one, of course. Ideas? Why is it coming back, and how can I get rid of it? Thanks
