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.
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.
