We have Active Directory Domain Controller Integrated with DNS Infoblox, the problem that when we decommission domain controller, the old SRV records remain in the Zone and we have to remove it manually . My Questions :

Is this normal behaver for Integrated DNS zone with Active directory & Infoblox as this not the case with Windows DNS?

How we can automatically remove the SRV records for decommission domain controller?

thanks

Hi,

 

you could search about enabling DNS Scavenging on Infoblox admin guide. 

DNS Scavenging is a feature that allows the cleanup and removal of stale resource records, which can accumulate in DNS zones over time with both dynamic and static DNS.

 

Thanks

Are you demoting the domain controller properly (eg. by using dcpromo)? If so then it should remove the associated DNS records automatically.

 

If you are simply powering it off without demoting it, the DNS records will remain and will need to be cleaned up manually.

Thanks Paulr,

Of course we demote the Domain controller properly,  but the case that I am not responsible for the Infoblox DNS, and my customer complaining that there is some residual DNS record left after proper removal, which is not the same case as with Windows DNS server.

In that case I think you should ask them to provide the list of records that they believe aren't being removed, we might find that they belong to another application that is unrelated to dcpromo. Do you have the list?
