Hi all
How to trigger "Update associated pointer (PTR) record" field for a DNS A record in Windows 2016 DNS servers?
When a PTR record for a DNS A record is deleted, the PTR record is not updated even "Update associated pointer (PTR) record"
is checked?
Thank you for your help!

That "Update associated pointer (PTR) record" is a GUI feature. You'd have to remove the A (and AAAA) separately, and then remove the associated PTR record(s) separately if you're using PowerShell to do the work.
You cannot recreate the missing PTR record using the DNS GUI by checking the "Update associated pointer (PTR) record" box and making a modification to the "A" record because there is no longer any PTR record associated with the "A" record.
You could do that with a PowerShell script, though. Retrieve the "A" record and, using the name and IP address from that record, create a PTR record in the reverse lookup zone for the network address.
Ensure the corresponding Reverse lookup zone is created on the DNS server; 2. If the dynamic update type is "Secure only", add the DHCP server to DnsUpdateProxy group; check if adding the DHCP server to the group could work.
Please keep me posted
Sorry that I did not state clearly. The DNS A records are for only servers which are assigned to static IPs.
It seems that if a PTR record for a server is deleted mistakenly, the PTR record is not updated even "Update associated pointer (PTR) record"
is checked. any idea how to trigger "Update associated pointer (PTR) record" field for a DNS A record to add PTR back?
Thank you for the help!
If the PTR record is deleted it's deleted!
Your original question asked about updating the PTR record, but that would only apply if the A (or AAAA) record was modified (e.g., changing the IP address). Deleting the A (or AAAA) wouldn't have any effect on the PTR record, and deleting the PTR record would have no effect on the A (or AAAA) record.
It's so clear what you said. Thank you!
anyway to trigger "Update associated pointer (PTR) record" field to add a PTR record back?
You aren't being clear about what is happening.
Which of these conditions are you talking about?
none of them.
my situation is that A and PTR records exist. somehow, the existing PTR is deleted. do not want to manually create.
then, ask anyway to trigger the field?
Thank you!
