Interesting. There's been a popular rumour that Microsoft availed
itself to the liberal BSD license, and availed itself to the FreeBSD
protocol stack. The rumor further said that if you pointed an OS
fingerprinting program at a Win2k box it would be identified as
FreeBSD.
That would not seem to be the case now (if it ever was). Attached
is the output of an nmap scan of my Sony Vaio with Win2k Pro.
And yes, it will respond to pings of any 127.0.0.0/8 address.
