Are there any VPN, or Firewall software of "second fully functionalmachine"?
When you start X-server do you get X-desktop?  
Can you run the following simple test from a bash shell?

>From Cygwin bash shell cd to /usr/X11R6/bin

DISPLAY=127.0.0.1:0.0
Export DISPLAY
./Xwin :0&
./xterm&
./twm&

You should see an X-desktop, then an xterm.  If Xwin does not start please
post exact error messages to the list.
