PTR Record disappearing from AD Integrated zone Oktay_Gür 6/20/2007 10:01:03 AM Hello, We have this weird occurance we have been trying to figure out recently. Every few days, we will have a record from DNS reverse zone (which is AD Integrated) disappear. The record that disappears is a Domain Controller. The forward record stays. Only the Reverse will disappear. There is no fix cycle. This happens randomly but every few days apart. Not a fix number of days. Just any day after few days. It has happened once or twice in succession like very next day or so. We have tried disabling auto registration on NIC. We have manually created DNS records (forward and reverse) using DNS. Nothing seems to help. It's really becoming more of a concern now as we have certain application relying on that which screams everytime that PTR disappears. Any and everything that can help is welcome. our system works ;w2k3 R2 with Exchange2003Ent.

This way any response would have hit all of them at the same time. Answay, as I responded and asked in the other newsgroup: Is the DC multihomed? What DNS addresses are in the DC's IP properties? Is the zone AD integrated or a primary or secondary zone? -- Regards, Ace This posting is provided "AS-IS" with no warranties or guarantees and confers no rights.
