    ·         (February 24, 2016) Microsoft has released KB3133717 which addresses an issue in which incorrect responses are received when an DNS server uses wildcard CNAME and Domain Name System Security Extensions (DNSSEC) validation failures in Windows Server 2012 R2. An update is available to fix this issue. Before you install this update, see the Prerequisites section.

    Issues that are fixed in this update
    Issue 1

    When DNSSEC validation is enabled on a Windows Server 2012 R2-based DNS server, the DNS server incorrectly reports the failed name validation when it receives a NODATA response and returns a SERVFAIL error to the client.
    Issue 2

    Windows Server 2012 R2-based DNS server doesn't return all the Resource record signature (RRSIG) records that should be returned with the Next Secure (NSEC) records if the query passes through a BIND forwarder during resolution. This causes DNSSEC validation to fail for any servers that are using Windows Server 2012 R2-based server as a forwarder.
    Issue 3

    Incorrect response to AAAA queries from Windows Server 2012 R2-based DNS server when a wildcard CNAME is used.
