Windows Server DNS root hints

Posted by bartvdw on 0202/0404/2012

Thanks to the integrated Best Practices Analyzer tools in Windows Server 2008 R2 I recently discovered that some DNS servers didn’t have the correct root hints configured. Found 2 excellent references regarding this, and this again proves the use of those BPA tools!

First link expains the warning reported by the BPA and documents the default list of root hints.

DNS: Root hint server <IP address> must respond to NS queries for the root zone
