SYMPTOMS

When a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based domain controller tries to dynamically register Domain Name System (DNS) records such as the Host (A) record, PTR record, and SRV record for the domain controller, the local Lsass.exe service randomly crashes. Additionally, because you cannot restart the Lsass.exe service, crashes in the service cause the domain controller to automatically restart. Such restarts may occur intermittently on a running domain controller. Or the restarts may occur every time that the operating system loads. Then, when remote computers try to discover such domain controllers by using DNS or by using network requests, services are either delayed or failed. This behavior occurs because the affected domain controller cannot dynamically register DNS records that are offline when you restart the computer.

CAUSE

This problem occurs because the DNS Client service or the Dnsapi.dll file uses an invalid pointer when the DNS dynamic update for the domain controller records exceeds the UDP packet threshold.

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
