Known issue wrt EDNS... http://support.microsoft.com/kb/832223
From: m b [mailto:[email protected]] Sent: Wednesday, December 15, 2010 9:15 AM To: NT System Admin Issues Subject: 2K8R2 DNS anomaly Within our forest, all domain controllers are DNS servers. We've been working to upgrade from 2K3 to 2K8. Most of those that are upgraded are 2K8R2, while a few are just 2K8. I have heard some reports from users that they were unable to access certain websites that they were able to access from home. Today's example is www.insead.edu<http://www.insead.edu/>. When I do an nslookup against any of our 2K8R2 DNS servers, the lookup fails to resolve. If I do that same lookup against any 2K3 or 2K8 DNS server, it is successful. I'm not seeing any common event log errors/warnings among the 2K8R2 DNS servers. My only hunch is root hints.
