Incomplete CNAME resource recordset is returned if a DNS recursive lookup fails in Windows 8 or Windows Server 2012


View products that this article applies to.

Symptoms

Consider the following scenario:
  • On a computer that's running Windows 8 or Windows Server 2012, you try to run a Domain Name System (DNS) query.
  • An incomplete alias (CNAME) resource recordset is returned if the DNS recursive lookup fails. For example, the recordset may be missing the A/AAAA record.
In this scenario, you cannot obtain the correct alias recordset in future queries of that DNS resource record for a particular time period. Additionally after the time period has expired, you still cannot successfully run a CNAME resource recordset query. This behavior occurs because the CNAME Time to Live (TTL) setting is returned from the previous failed recursive lookup.

Cause

This problem occurs because of an issue in the way that the DNS client caches the CNAME resource recordset.
