# *NdisDeviceType    
#   
# The type of the device. The default value is zero, which indicates a standard   
# networking device that connects to a network.   
#   
# Set *NdisDeviceType to NDIS_DEVICE_TYPE_ENDPOINT (1) if this device is an   
# endpoint device and is not a true network interface that connects to a network.   
# For example, you must specify NDIS_DEVICE_TYPE_ENDPOINT for devices such as   
# smart phones that use a networking infrastructure to communicate to the local   
# computer system but do not provide connectivity to an external network.    
#   
# Usage: run in an elevated shell (vista/longhorn) or as adminstrator (xp/2003).
