A DirectAccess access failure occurs after the DNS servers that are running Windows Server 2008 return empty responses for AAAA queries in a WINS zone


View products that this article applies to.

Symptoms

Consider the following scenario:
  • You click to select the Use WINS forward lookup check box to forward name resolution queries in a Domain Name System (DNS) zone. You configure the DNS zone to forward the name resolution queries to a Microsoft Windows Internet Name Service (WINS) server within an organization.
  • A Windows 7 client tries to connect to the network of the organization by using the DirectAccess feature.
In this scenario, all Windows 7 clients that have the DirectAccess feature deployed lose local name resolution. Additionally, these clients cannot connect to any local resource by using local name resolution.

Cause

The DNS servers that are running Windows Server 2008 use a "Success/No-records" response to AAAA queries (queries for a host address record in IPv6 address format) if the name does not exist in the WINS database. However, if the name does not exist in the WINS database, the expected response is "Name Error."

In the DirectAccess scenario, clients depend on the "Name Error" response before they fail over to the local name resolution. Therefore, these clients do not fail over to the local name resolution, and these clients cannot access the local network resource.
