DNS Server service randomly cannot resolve external names and returns a "Server Failure" error if IPv6 is disabled in Windows Server 2008 and Windows Server 2008 R2

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You install the DNS Server role on a computer that is running Windows Server 2008 or Windows Server 2008 R2.
  • You disable IP version 6 (IPv6) on the computer.
  • You configure the DNS server to use root hints to resolve external name resolution.
  • The DNS Server service receives some external name resolution requests.
In this scenario, the DNS Server service randomly returns the following error message:
Server Failure
Additionally, users cannot access some Internet network resource if they use the DNS server to resolve external names.

For example, users cannot access some websites.

Note If you collect a network trace when this issue occurs, the trace contains the following network packets:
<IP> <IP> DNS DNS:QueryId = 0x1C, QUERY (Standard query), Query for <name> of type Host Addr on class Internet
...
<IP> <IP> DNS DNS:QueryId = 0x1C, QUERY (Standard query), Response - Server failure

Cause

This issue occurs because the DNS Server service does not check whether IPv6 is disabled when the service selects an IP address to send the next DNS query.

When the DNS Server service queries the name server for an external name resolution request, the Internet DNS server returns an IP address list that contains IP version 4 (IPv4) and IPv6 addresses. However, the DNS Server service does not check whether IPv6 is disabled when the service selects an IP address to send the next DNS query. The service may select an IPv6 address when IPv6 is disabled. Therefore, the DNS Server service does not send the next DNS query, and this issue occurs.
