Windows DNS server incorrectly parses client computer records

Symptoms

Consider the following scenario:
  • You have a DNS server that's running Windows Server 2012 R2 or Windows Server 2008 R2 Service Pack 1 (SP1).
  • You perform an incremental zone transfer (IXFR) by using a DNS BIND implementation to this DNS server.

In this scenario, you discover that the Windows DNS server incorrectly parses some client computer records, such as address (A) resource records and text (TXT) resource records. Additionally, incorrect data such as IP addresses are attached to the zone's name, where the zone's name is the same as the name of the parent folder.

Note This problem does not occur when both DNS servers are Windows DNS servers.

Cause

This problem occurs because Windows DNS incorrectly handles the IXFR requests.
