Thanks for the response, I truly appreciate it.
I was incomplete in my message. 

I had already looked at the packages mentioned in 
section 22.3 of the DJGPP FAQ list (v2/faq211b.zip),
but each of those, from the documentation, seem to 
require a separate configuration of TCP/IP from what 
has already been done in Win95 (if I am incorrect, 
someone please correct me). My users are not 
technical by any stretch of anyone's imagination. As
such, I want to avoid having them do anything more 
than copy the file from a server and put it where it
needs to go. I also want to avoid running separate 
TCP/IP stacks. I was under the impression the only 
way to accomplish each of these tasks was to use 
the winsock.dll that comes with win95 (Again, if I 
am wrong, please correct me). I currently have no 
clients less than win95, although its likely I will 
end up with Win/NT and Win98 clients in the not too 
distant future. I'm hoping that by dynaimcally linking
to the winsock.dll provided by MS, I will avoid having \
to compilations (or ports) separate versions of the client.

Thank you! May I suggest an addition to the FAQ about issues
involved in a port from Unix to MS-Dos/Win95/Win98? This 
would include issues like the different packages for sockets 
that require separate configuration, as well as the Win32 
program issue, and any gotchas like whether the use is 
WSAStartup() and associated routines are needed, or suggested.
