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

- Microsoft Windows for Workgroups version 3.1 
-------------------------------------------------------------------------------

The following article contains information on the use of Windows for
Workgroups with third-party products or configurations that have not
been tested and are not supported by Microsoft.

If the steps or procedures described in this article do not function
properly, contact the manufacturer of the third-party product for more
information or use a supported configuration.

SYMPTOMS
========

The Standard Microsystems Corporation (SMC) network interface card driver
(SMCMAC.DOS), which is included with Windows for Workgroups version 3.1, does
not support using two SMC network cards at the same time. Windows for Workgroups
does not display a warning message and will allow setup for two SMC network
cards. If two SMC network cards are set up with the SMCMAC.DOS driver, the
following error message appears when you start the machine:

  Error 5733: The protocol manager has reported an incomplete binding.

CAUSE
=====

This is a limitation with the SMCMAC.DOS NDIS driver and applies to both
Microsoft LAN Manager and Windows for Workgroups. SMC has a workaround for this
limitation for Microsoft LAN Manager, and it should also work with Windows for
Workgroups.

WORKAROUND
==========

To work around the limitation, use the following steps.

1. Obtain the self extracting archive file NDS119.EXE, from either the SMC forum
  on CompuServe or directly from SMC. This file contains another NDIS driver
  for the second network card.

2. Run the NDS119.EXE file and once the files have been extracted, copy the file
  SMCMAC2.DOS to your Windows for Workgroups directory.

3. Start Windows for Workgroups and open the Control Panel from the Main group
  and select Network, Adapters.

4. If there are already two drivers installed for the SMC network cards, then
  exit Windows and skip to step 6. Otherwise, choose Add.

5. Select an appropriate network card driver for the second SMC network card,
  configure the correct settings for the card, and choose Restart Computer when
  prompted.

6. Edit the CONFIG.SYS file and add any of the following lines if they are not
  present, or modify any lines that need to be, so they match the below lines:

        DEVICE=<Windows Path>\PROTMAN.DOS /I:<Windows Path>
        DEVICE=<Windows Path>\SMCMAC.DOS
        DEVICE=<Windows Path>\SMCMAC2.DOS
        DEVICE=<Windows Path>\WORKGRP.SYS

7. Restart the computer by turning it off and on.

  NOTE: The SMCMAC2.DOS driver is written so that it may require the computer be
  restarted to properly initialize.
