To use nmapNT under windows, you must have the libpcap drivers loaded. These
are packet drivers and install just like any normal network driver.
Alright here is the most basic guide to installing the packet driver.
Goto the properties for your network card.
You will want to install a new "protocol".
Click the browse button.
Now navigate to NmapntDRIVERSPacketNT (NT4)
or to NmapntDRIVERSPacket2K (Win2k)
Click ok a few times to back out of the network dialog boxes.
You will be asked to restart your computer, restart it.
Even if you are not asked to reboot, reboot otherwise the driver will not work correctly.
