Disable eDNS on Windows 2008 R2

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:

Dnscmd /config /enableednsprobes 0

My question -- are they any issues with disabling eDNS on Domain Controllers? Anyone had experience with this?

Hello,

Instead of disabling eDNS, maybe you can have a look on "enabling aging and scavenging mechanism for the DNS Server service" ?
See this link for details : http://technet.microsoft.com/en-us/library/cc771362(v=ws.10).aspx

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.

eDNS was not enabled under Windows 2008 but it is under R2.
If you are not using DNSSEC it looks safe to me to disable it.
