Hi, I tried to delete a static PTR record in an AD-integrated zone. However the record reappears immediately after hitting F5. The DNS MMC Snap-in doesn' report any error. I also tried to delete the PTR record via dnscmd /recorddelete. Same issue... Command completed successfully. no error. The DNS zone is stored in the domain partition (All domain controllers in this domain). It was never changed after updating AD from Windows 2000 to Windows 2003 to Windows 2008 DCs. After some research I found out that there was no "dnsNode" object in AD for this PTR record. My question is, how can I get rid of this PTR record? And what are the places where the DNS service on a DC can store its zone information? (I thougt that when a DNS zone is configured with the replication option "All domain controllers in this domain" that all records are stored as dnsNode objects in the domain partition under cn=MicrosoftDNS,cn=system,dc=domain,dc=tld ?) Many thanks in advance for help! Mario
