Upgrading LAN Manager 2.1 to WFWG 3.1 with EtherExpress Card (91099)
The information in this article applies to:
- Microsoft Windows for Workgroups 3.1
This article was previously published under Q91099 SYMPTOMS
When upgrading from Microsoft LAN Manager version 2.1 to Windows for
Workgroups version 3.1, Setup uses the default settings for the network
card. Windows for Workgroups takes the network card settings used by LAN
Manager 2.1, and finds that no setting is specified for the IRQ. Windows
for Workgroups then uses the default IRQ for the network card. When the
system is restarted, the following message is displayed if the default IRQ
is not correct for your machine:
Protocol Manager did not accept EtherExpress 16 driver.
NDIS environment invalid, Driver not loaded.
CAUSE
If Setup detects that LAN Manager 2.1 was previously installed, it attempts
to take the safest route of using settings from LAN Manager. Unfortunately,
some of the settings used in Windows for Workgroups are not required for
LAN Manager, particularly for the EtherExpress card.
WORKAROUND
To correct the problem, use the Network option in Control Panel to
adjust the IRQ setting for the card to its proper value.
