I doubt it.  The stack was in user space until NT/2000;
that's why sockets could not be treated as file descriptors.

Actually, you can allocate anonymous completion ports,
and use aprtment model threading to get the same effect
in 95/98, but who's counting?  8-).

The file you are looking for is WSOCK32.DLL, the 32 bit
WinSock library.  Preferrably, you will use the version
from the developer CD, since it has debugging information
and many more unstripped strings.  If you have a copy of
"Visual InterDev" or even just a vanilla "Visual C++",
it should be an easy find.

Also I suggest looking at the "Early Availability Technology
Preview" for their IPv4+IPSEC/IPv6 stack.
