Access Violation in Dns.exe When Logging Is Enabled (314803)
The information in this article applies to:
- Microsoft Windows 2000 Server SP1
- Microsoft Windows 2000 Server SP2
- Microsoft Windows 2000 Advanced Server SP1
- Microsoft Windows 2000 Advanced Server SP2
This article was previously published under Q314803 SYMPTOMS
The DNS service on your Windows 2000 DNS server with logging enabled may stop responding (hang) and generate an access violation error message. Your event logs may show Events 5504 and 5506 just before the service hangs.
CAUSE
Certain queries to the DNS server (like a reverse lookup) result in a response that contains a damaged data section, and this can occur when the data in the packet uses compression. The damaged data packet causes the buffer to be overrun, which causes the DNS service to generate an access violation error message and hang.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the
