Script to change VMWare's NIC adapter types so that it doesn't influence the Windows Firewall's understanding of how the machine is connected to the network. This can be useful when using VMWare workstation. I found it on the web somewhere.. can't remember where.

#  
# *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).
