TITLE   :Xircom Creditcard Ethernet+modem Fails After SP2 or 3
PRODUCT :Microsoft Windows NT
PROD/VER::3.51
OPER/SYS:
KEYWORDS:

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

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

SYMPTOMS
========

You are using the driver supplied by Xircom for the Xircom Creditcard Ethernet+
28800 modem under Windows NT 3.51 and after upgrading your laptop to Windows NT
Service Pack 2 or 3, the driver fails to load with the following message
registered in the event log:

   Event ID: 7000

      Description: The Xircom CreditCard Ethernet+Modem II Driver service
      failed to start due to the following error: A device attached to the
      system is not functioning.


CAUSE
=====

The updated PCMCIA.sys driver set up by the Service Pack update appears to have
prevented the Xircom driver from loading. This is the result of a regression
introduced in Service Packs 2 and 3; the regression is fixed in Service Pack 4.

RESOLUTION
==========

To solve the problem, either upgrade to Service Pack 4 or for a temporary
solution, replace the PCMCIA.sys driver with the version shipped on the Windows
NT 3.51 compact disc (which can also be found on disk 2 of the disk set) as
follows:

1. At the command prompt, change into the directory
   %Systemroot%\System32\Drivers

2. Rename PCMCIA.sys to PCMCIA.new.

3. Expand PCMCIA.SY_ from the \I386 directory on the compact disc using the
   following command line:

   EXPAND <CD>:\I386\PCMCIA.SY_ PCMCIA.SYS

   or, if you are expanding the copy from disk 2, the command is:

   EXPAND A:\PCMCIA.SY_ PCMCIA.SYS

After you have replaced PCMCIA.sys, shut down and restart the system.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51 Service
Pack 2 and 3. This problem was corrected in the latest US Service Pack for
Windows NT. For information on obtaining this update, query on the following
