Broken AD Integrated DNS Zone

Last Modified: 2015-07-28
I have an existing active directory integrated DNS zone - let's call it company.com

I was trying to create a subdomain A record using dnscmd, and used the following commands

    dnscmd /zoneadd sub.company.com /DsPrimary /DP /domain
    dnscmd /recordadd sub.company.com webserver A

I realize now that this is incorrect syntax, however, I cannot delete this single subdomain. When I try to delete sub.company.com in the DNS GUI, it appears to delete, but the AD DNS servers still answer queries for the webserver.sub.company.com A record - even though it doesn't exist. I've tried a zone reload, server reboot, to no avail.

The only information I've seen about cleaning up bad records in an AD integrated zone is this from Microsoft:


This involves deleting the zone and adding it back in. As this zone is critical to a number of applications, and we have 7 domain controllers in 5 locations, it's a scary proposition.

Does anyone know how I can clean up the sub.company.com zone without deleting and recreating the entire company.com zone?
