Hello,<br />
<br />
Instead of disabling eDNS, maybe you can have a look on &quot;enabling aging and scavenging mechanism for the DNS Server service&quot; ?<br />

Thanks for this. The problem happens before the records go stale, however. There's a bit more to the story, and there appears to be some buggy behavior involved in what is happening. I can't explain it effectively in such a small space unfortunately.

We have a Windows 2008 Domain Controller running on a Windows 2008 R2 server. This DC also runs DNS. We have an issue with some records not being cleared out of the DNS cache, and we are confident it can be resolved by disabling eDNDS (extended DNS) with this command:<br />
<br />
Dnscmd /config /enableednsprobes 0<br />
<br />
My question -- are they any issues with disabling eDNS on Domain Controllers? Anyone had experience with this?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.
