Help with creating Python COM

[Charlotte Williams]

I am following a tutorial for creating a Python COM server that will
interact with a Visual Basic client.  The author included an example with a
set of instructions.  However, when I go to register the COM, it gives me an
error.  When I went back into the debugger and tried to debug the python
script, it tells me

ImportError: No module named ni

All the tutorials I have encountered tells me that these are the modules
that must be imported:

 import ni
 from win32com.server.exception import Exception
 import win32com.server.util

I am running PythonWin with Python 2.0 (BeOpen).  The link to the tutorial
is here:

Any knowledge of what I am doing wrong?
