wine users - Feb 2011 - how to install "missing" netsh.exe using commands?

After trying to install Tunngle on Wine I came upon this error:
_______________________
unable to execute file:
netsh
CreateProcess failed; code 2.
File not found
_______________________

I have scoured the internet for a fix for this problem to no avail. It seems it
isn't just the program I'm using, it's a fairly common(ish) problem.

The closest I came was with this forum here:

Now, I asked my windows friend user to send me the netsh.exe file hoping that
would solve it.

How would I install it using scripts? As I only have a pseudo-file for Wine (as
I'm running OSX - for mac - and it being a Linux program). OSX's
Terminal uses the same commands as Linux's version so would just need a
step-by-step guide in Layman's Terms on how to place the netsh.exe file in
the corresponding Wine folder.

Unless of course there is an easier way?

What happens if you copy a dummy .exe to netsh.exe, e.g.
just write a C program that does
  main() {
     return 0;
  }
compile that with mingw, and copy the resulting .exe to c:/windows/system32 ?

theunknown_  Tunngle will be dead on arrival.    Wine does not have its own
networking stack.

VPN programs have to be done naively under Linux.  There is no way for wine to
support this since network alterations are above what a general user should be
doing.

So you will have to ask for Tunngle to be ported.   Yes its a windows only
network completely excluding OS X and Linux.   Wine does not help you here.
