HI all,
We have weird DNS issues and found out production servers DNS records are deleted by scavenging. We have Windows 2019 domain controllers. Is there a way to check whether these records are stale or timestamp?
Thank you!
@John JY check this article and ther is a script that can help you in one of the comments. I do not want to copy paste due to reasons, but I think it should help you to extract the timestamp.https://web.archive.org/web/20160428150734/https://blogs.technet.microsoft.com/networking/2008/03/19/dont-be-afraid-of-dns-scavenging-just-be-patient/
Hi JimmySalian, thanks for the great article. BTW, how client update the timestamp? through which service?
"The client is allowed to come in and update it’s timestamp."
Hi John,
No worries and you are welcome, well it is via the refresh interval setting and you will need to read through this to understand this process. - https://chrisbrown.au/techblog/how-dns-aging-and-scavenging-actually-work/
