Re: Disappearing DNS PTR entry

Are you trying to create the PTR record in your own SBS DNS record? If so thats not where you need it.

It needs to be in your public DNS records and is usually created by the ISP who supplies your IP addresses, but could also be done whereever you site is hosted.

I have a PTR record that disappears from the RDNS lookup. The A record is
never affected and is always in the forward lookup. This record is the DC. We
noticed it and manually added it back only for it to be removed a couple
hours later. I then recreated the A record in the forward lookup zone and had
it recreate the PTR record. The PTR record was gone a few hours later. I then
found an article saying to disable the Scavenge stale resource records and
manually add the PTR record again. I did that and the record disappeared
again.

I have seen a couple articles with this exact problem but it wasn’t
explained what caused the problem. I want to know why this is happening and
what to do to fix it. Any help would be appreciated.

Thank you.
