change static Active Directory DNS record to dynamic
For our servers, i have manually changed some of our critical DNS records to static, as DNS was in bad shape when i arrived and wanted no potential hiccups on a production network. Now that scavenging is fixed and shown to work for DHCP client systems and the server records are in order, i'd like to get back to dynamic records for the servers so no manual deletions will be needed going forward. I've found online that registering manually at the server usin ipconfig /registerdns is supposed to initiate the record to go dynamic, but that hasn't worked. How can i get my servers back to dynamic A records?

DNS/other servers were rebooted doin the MS updates for the month already. we only do secure updates and AD integrated. would it not work with these settings?

was that the correct method? or is there a better step by step to be sure i did it correctly other than just running ipconfig /flushdns from the problem computer only?
I would leave it at secure only.
To change the record to dynamic, in the DNS console under View make sure you have Advanced checked > then go to the record > right-click and choose Properties > then check the box to delete the record when it becomes stale. When you hit Apply you should see a timestamp on the record. However, there have been times where I have seen this not stick for some reason. In that case I would suggest deleting the record, then run ipconfig /registerdns on the server so that it will recreate the record. This also has the benefit of ensuring that the security on the record is correct.

DrDave242, you are correct. the syntax after testing and creating a test zone is:
dnscmd /ageallrecords FQDN_zone_name server_name /f
(also have to have scavenging on the zone set or it will fail)
the /f is to not prompt "are you sure" type of thing.
thanks everyone. that did it.
dnscmd /ageallrecords FQDN_zone_name server_name /f
(also have to have scavenging on the zone set or it will fail)
the /f is to not prompt "are you sure" type of thing.
thanks everyone. that did it.

If so and no change, have you rebooted?
