Are "Refresh" and "No Refresh" intervals checked for DNSTombstoned=TRUE objects?

-

hello all,

thank looking, hope can find clarification understanding of dnstombstone / update scenario.

i have been troubleshooting issue in production dns server couple weeks now, , believe have narrowed down.  have made couple of assumptions need verify before able report on issue.

the problem:

initially noticed our ad-integrated dns zone , dhcp servers having trouble host (a) records, intermittently.  of our client machines write own host records (as configured) , dhcp write ptr records (as expected).  every , there ptr record written dhcp doesn't have host (a) records associated it. 

the obvious first step ipconfig /registerdns client in question, doesn't work.  "dnsapi" event error saying request has timed out, , led me on wild goose chase.  have gotten point no longer believe event direct result of cause of problem.

so moving on... started looking @ our "partially configured" not enabled scavenging settings.  know deleted record have dnstombstone attribute set "true", , available refreshed client until such time has been garbage collected.

my question:

will "no refresh" interval prevent dnstombstoned=true object being "updated" , therefore not have record (in case host (a)) resisted in dns?

the reason led make assumption host computers seem not writing own host (a) records degree of consistency write them if left alone length of time.

i think seeing is:

1. record gets deleted (probably manually in case)

2. record within no refresh interval

3. host attempts update record (via ipconfig /registerdns)

4. record update denied due no refresh interval

5. error written in event log on host machine.

am on right track?  if not can 1 suggest anything?

thank,

jalgl

you should able ipconfig /registerdns machine set update dns.  should able 10 times in minute, if choose.  if can't that, have problems.  why being unable update record within dns wild goose chase?

i find host can't update , set dns logging , run ipconfig /updatedns , review logs.
