THAT was the stack that was reportedly based on NetBSD 1.3.3. The NT 5.0
(nee Windows 2000) Beta5 TCP/IP stack would be reported by various network
scanners as the NetBSD 1.3.3 stack, which led to widespread rumors that
the code was a port from NetBSD. I suspect you would need to look at the
code itself to determine that is true, or get someone at Microsoft to tell
the truth. Yeah, like that's gonna happen.

Neat hack.
