SYMPTOMS

In Windows Server 2008 or Windows Vista SP1, applications or services that use sockets may stop responding.

For example, a Windows Server 2008-based domain controller randomly becomes unresponsive to LDAP requests. After this issue occurs, you have to restart the server.

CAUSE

This issue occurs because of an error in the TCP/IP (Tcpip.sys) driver.

A thread owns a critical section and calls the closesock function. However, the closesock function never returns. Therefore, other threads cannot access the critical section and stop responding.

RESOLUTION
