The problem is that even though you have Cygwin you do not have an X environment to execute X applications as NAM. The solution to this problem, would be to install (in addition to cygwin), the KDE ebvironment for Windows, that co-operates with cygwin.
In this way you will have an X desktop, which will provide you with the appriopriate $DISPLAY variable for your X environment. NAM is an X windows application, so it must have an X Desktop (environment) to run. I use KDE with cygwin in my Windows NS-2 machines successfully. You can find it here: http://kde-cygwin.sourceforge.net/. However, please note that you need to have Windows 2000 or XP in order to be able to install the KDE Desktop. After the installation of KDE you will be able to execute ns and run your scripts, via the KDE desktop by opening a Terminal program. Also note that KDE requires to already have installed cygwin, on top of which will be installed. Then you execute KDE to load the desktop and from there you execute a terminal program (through the Graphical Menus) to have access to the bash shell.
