SYMPTOMS
========

Windows NT Server may trap when LAN Manager 2.x compatible clients with oplocks
disabled attempt to open a file that is already in use by a client that supports
oplocks. The following stop message may appear on your Windows NT server:

  STOP 0x0000000A (0x00000104, 0x00000002, 0x00000001, 0xfbd6bde0)

NOTE: Although the last parameter differs depending on the system configuration,
it will fall within a protocol driver. In this case, the Stop occurred in
Nbf.sys.

CAUSE
=====

LAN Manager clients that have oplocks disabled can trap a Windows NT 4.0 server
because I/O requests submitted to the transport may get queued and completed
after the server has already reused the I/O request structure.

This issue is unique to LAN Manager compatible clients because it requires the
create file Server Message Block (SMB) request to occur.


RESOLUTION
==========

Code was added to Srv.sys to allow create file requests from non oplock clients
to gracefully timeout before reusing the IO request.

It is also possible to workaround the problem by enabling oplocks on LAN Manager
2.x compatible clients.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Windows NT version
4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S.
Service Pack. For information on obtaining the service pack, query on the
