Article: Q235409
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbWinNT4sp6fix
Last Modified: 20-MAY-2002

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

- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
- Microsoft Windows NT Workstation version 4.0 
- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

A problem exists in the SpRemoveDevice function in the Scsiport.sys driver. This
function is responsible for cleaning up logical unit number (LUN) information
stored in the SCSI port driver. The function does remove the LUN information
from its internal storage, but it does not update its count for the number of
logical units. Because the count update is incorrect, you may experience
problems viewing the SCSI inquiry data by using the SCSI Adapters tool in
Control Panel.

RESOLUTION
==========
