haha! How about that. It does crash... hmmm...

Sorry, I didn't test it at the time of writing the post... just went from past experience.

It will allow you to ping individual hosts if they are there or not... seems to have a problem as soon as you add the subnet... which is why you'd want to use the -sP option. bugger.

Using nmap 3.81 with the winpcap 3.1beta4 drivers...

nmap -sP 192.168.1.1 works and is up
nmap -sP 192.168.1.2 works but is down
nmap -sP 192.168.1.0/24 gives me an interface error on xp pro sp2 all updates
nmap -sP 192.168.1.0/24 gives me time errors on 2k sp4 all updates
