Product(s): Microsoft Windows NT
Version(s): winnt:3.51
Operating System(s): 
Keyword(s): kbother

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

- Microsoft Windows NT Workstation version 3.51 
- Microsoft Windows NT Server version 3.51 
-------------------------------------------------------------------------------

SYMPTOMS
========

An Int21 call, Random Write (22H), from a client running Windows for Workgroups
or Windows95 to Windows NT fails. As a result, if you run an older application
on the client that relies on the Int21 call, you cannot write to a network drive
on computer running Windows NT server.

CAUSE
=====

Reading the trace on SMB Response Open&X from Windows NT, the Open Mode is
0x00FF instead of 0x0072.

WORKAROUND
==========

Use Handler functions instead of FCB calls.

RESOLUTION
==========

To correct this problem, install the fix mentioned below.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. A fix
to this problem is in development, but has not been regression-tested and may be
destabilizing in production environments. Microsoft does not recommend
implementing this fix at this time. Contact Microsoft Product Support Services
for more information on the availability of this fix.
