Here's something interesting...
Open up any copy of ftp.exe in Notepad and scroll down a bit.
It states Copyright (c) 1983 The Regents of the University of California
Yep, my guess is they lifted virtually the whole TCP/IP stack right from BSD Unix...
That's interesting, but it's not illegal if the BSD license back then was the same as it is now. The BSD license basically allows anyone to copy and use the code without restriction, with the only condition being that they maintain the original headers (which MS apparently did in this case). I don't begrudge MS one bit for doing that.
But the idea that MS was on the cutting edge in OS design is just a pathetic joke. Heck, unix had a multiuser system a friggin' QUARTER CENTURY before MS had one! And I just read the other day that MS didn't even have subdirectories until around 1985, and they used the "\" character as a delimiter in a pitiful attempt to be different from unix (which uses "/", of course).
Typical BS from you. Microsoft didn't "lift" it from anyone, they bought it from another company named Spider. You can read it here from one of the admins at freebsd.org, or try some actual research yourself instead of parroting the normal nonsense you hear from your uninformed buddies:

Q: Is it true that Microsoft uses BSD's Stack?
A: No, it's not true. For a while we thought it was, but we proved to be incorrect. Microsoft's network stack was written by a Scottish company called Spider.
