SYMPTOMS

Consider the following scenario. You develop a Windows Filtering Platform (WFP) driver. You install the WFP driver on a Windows Vista-based computer. In this scenario, some applications and services appear to stop responding for 15 seconds when a Domain Name System (DNS) lookup occurs. This problem occurs if the applications or the services use the DNS function.

CAUSE

This problem occurs because of an error in the Application Layer Enforcement (ALE) component.

After the Getaddrinfo function receives a DNS response, Getaddrinfo tries to close a socket. At the same time, the ALE component detects that some pending net buffer lists (NBLs) exist in Windows Vista. Then, the ALE component puts the socket in a queue. The socket stays in the queue for 15 seconds. Therefore, the applications or the services appear to stop responding for 15 seconds.

RESOLUTION

Update information

To resolve this problem, apply the update on the Windows Vista-based computer. This update removes the code where the ALE component put the socket in the queue.
