AUTION
If any other software requiring the Base driver (such as
SNA Link Services) is installed in your system, do not
remove the Base driver with the NDIS driver.
If you want to remove both drivers, remove the NDIS driver
first.
If multiple NDIS logical adapters are configured, you must
remove all of the logical adapters to remove the NDIS driver.
Removing the final logical adapter removes the driver.
Removing the NDIS Driver
To remove the NDIS driver, do the following:
1. Be sure you are logged on with administrator rights
to the Windows NT 4.0 system.
2. From the Start menu, select Settings, and then Control
Panel. Then double-click the Network icon, and select
the Adapters tab to display the Adapters dialog box.
