Article: Q157301
Product(s): Microsoft Windows NT
Version(s): 3.51 4.0
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Workstation versions 3.51, 4.0 
- Microsoft Windows NT Server versions 3.51, 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When two or more 16-bit named pipe clients are run, and the first instance of
the named pipe client is terminated, all other 16-bit named pipe client
instances may receive a general protection fault at 0001:0CE6 in Netapi.dll.

CAUSE
=====

The Netapi.dll in Windows NT 3.51 and 4.0 does not handle the DosReadAsyncNmPipe
and DosWriteAsyncNmPipe API correctly.

RESOLUTION
==========

To resolve this issue, run each 16-bit named pipe client in a separate memory
space.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT versions 3.51 and
4.0. We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
