View products that this article applies to.

Symptoms

On a Domain Name System (DNS) client computer that is running Windows Vista Service Pack 1 or Windows Server 2008, the DNS Client service and the Network Location Awareness (NLA) service crash intermittently.

This issue occurs if the DNS client has dynamic DNS registration enabled when the client performs a DNS registration.

Notes
  • By default, dynamic DNS registration is enabled in Windows Vista-based and Windows Server 2008-based DNS clients.
  • This issue does not occur if the DNS client is running the RTM version of Windows Vista.
