DNS Clearout procedure

[Aelara]

Hello, Have a situation were the DNS server on both the Forward and reverse lookup zones have many decommissioned workstation names/entries and IP's for both the Host(A) records and Pointer(PTR) I am running a couple of utilities dependent on these entries and in most cases they resolve the wrong name due to the multiple entries per IP address.

What is the safest way to clear them out and start again? I could just delete all A and PTR records and let them register when the workstation logs on to the Domain but I may be going about it the wrong way. Any advise?

Aelara.

Look into DNS aging/scavenging. That should resolve the problem.

You could probably achieve what you want to do using the DNSCMD command line utility with the /NODEDELETE switch. That should kill only the records in a particular node as long as you don't use /TREE with it. You could also use the /AgeAllRecords and then run it again with /StartScavenging to kill the records as 58sniper says above.
