SYMPTOMS
========

If you run a program that uses Windows Sockets on Terminal Server Edition, you
may receive an error message similar indicating that an entry point is missing
from Ws2_32.dll, as shown in the following examples:

  Run-time error '453' Can't find DLL entry point WPUCompleteOverlappedRequest
  in ws2_32

  Run-time error '453' Can't find DLL entry point WSAProviderConfigChange in
  ws2_32

NOTE: The exact format of the error message depends on the software development
environment used to build the program.

CAUSE
=====

The WPUCompleteOverlappedRequest and WSAProviderConfigChange entry points are
not exported by the version of Ws2_32.dll that is included with Terminal Server
Edition. Therefore, they are inaccessible at run time.

RESOLUTION
==========

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

WORKAROUND
==========

Ws2_32.dll file with the version of this file that is included with Windows NT
4.0 Service Pack 5.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT Server 4.0, Terminal
Server Edition. This problem was first corrected in Windows NT Server version
4.0, Terminal Server Edition Service Pack 6.
