The information in this article applies to:

- Microsoft Windows NT Workstation version 4.0

SYMPTOMS
========

Sockets-based child processes are not stopped and appear as "zombie processes."

CAUSE
=====

There is a timing window where the TCP connection is not closed correctly on the
Windows NT side and data that has not been acknowledged yet is discarded.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or
Windows NT Server 4.0, Terminal Server Edition. For additional information,
please see the following article in the Microsoft Knowledge Base:

  Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT
Server 4.0, Terminal Server Edition. This problem was first corrected in Windows
NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition
Service Pack 4.

MORE INFORMATION
================


Zombie processes are child processes that are no longer running, but the kernel
still needs to keep information about them. In this case, these processes are
waiting for an event that never comes.
