SYMPTOMS

When the NET START command is executed, you receive one or more of the following error messages

Failure: PROTOCOL.INI does not have a DRIVERNAME=xxx.

Failure: Protocol Manager did not accept xxx.

Failure: NDIS environment invalid. Driver not loaded.

Error loading device driver xxx.

Error 7306: The driver failed to initialize.

xxx was not loaded.

Error 7321: Network card drivers failed to load.

where "xxx" is your network card driver name (for example, EXP16 or EXP16.DOS).

CAUSE

If you install a second network interface card (NIC) of the same brand and model as the original and then load an NDIS 2 (real-mode) driver and protocol for this card, you encounter problems if the initial adapter is using an NDIS 3 (protected-mode) driver and protocol.

Because an NDIS 2 driver must run in real mode, it is initialized before Windows for Workgroups 3.11 is loaded. The adapter binding with the NDIS 2 driver becomes the first physical adapter. To complete the binding process, the NDIS 2 driver looks in the PROTOCOL.INI file for a DriverName=FirstDriverInstance$ setting. Because an NDIS 3 driver was installed first, no such setting exists since NDIS 3 drivers do not require this setting.

RESOLUTION

To avoid the above error messages, perform the following steps:

Choose the Network Setup icon in the Network group.
Choose the Drivers button.
Remove both network card drivers.
Choose Close, then choose OK. (Allow Windows to reboot the computer when you are prompted to do so.)
Restart Windows.
Choose the Network Setup icon in the Network group.
Choose the Drivers button.
Add the network card driver for your network card.
Set up this card with the NDIS 2 driver and protocol.
Add the second instance of the network card driver for your network card.
Set up this card with the NDIS 3 driver and protocol.
Choose Close, then choose OK. (Allow Windows to reboot the computer when you are prompted to do so.)
