The information in this article applies to:

- Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 
- Microsoft Windows NT Server versions 3.5, 3.51, 4.0 
- Microsoft Windows for Workgroups version 3.11 
- Microsoft Windows 95 
-------------------------------------------------------------------------------

SYMPTOMS
========

Applications on Windows 95 or Windows for Workgroups 3.11 may fail while writing
data to a computer running Microsoft Windows NT server over the NWLink protocol.
The problem occurs only when direct hosting over NWLink is used. Direct hosting
is a method of bypassing the NetBIOS layer and sending client/server message
blocks (SMBs) directly over the NWLink protocol.

When the problem occurs, the application on the client computer may display the
following message:

  Error 55: The specified network resource or device is no longer available.



WORKAROUND
==========

The workaround involves disabling direct hosting. To turn off direct hosting,
disable the NWLink IPX/SPX binding in Windows NT Server service. After this is
done, enable NWLink with NetBIOS on the client computer.

Knowledge Base:

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.5x and 4.0.
We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
