Article: Q299364
Product(s): Microsoft Windows NT
Version(s): 4.0 SP6a
Operating System(s): 
Keyword(s): kbWinNT400PreSP7Fix

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

- Microsoft Windows NT Server version 4.0 SP6a 
- Microsoft Windows NT Workstation version 4.0 SP6a 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you insert an unconfigured PC Card, Windows NT 4.0 may become unstable or an
access violation may occur in Services.exe. An unconfigured PC Card is a card
for which drivers have not been loaded yet.

CAUSE
=====

When you insert a PC Card for which Windows NT 4.0 does not have drivers, the
PCMCIA driver attempts to log the following event:

  Event ID: 5
  Source: PCMCIA
  There is no configuration information for the PCCARD "(Device Name)"

However, the driver does not calculate the size of the event log entry date, and
this may cause an access violation in Services.exe.
