This may be a case of the truly blind trying to lead the blind... I run
W/ME and the closest I have come to IIS is running PWS for a short
while long ago.

Let's ignore the diffs problem for a moment, it seems to be similar to
the other problem.

When you say you made your DarwinWiki directories writeable... don't
you have to set both XP permissions and IIS permissions separately? 

I am thinking that these instructions...

'''
Now follow the same steps, but set the alias to "mywiki" and the path
to "C:\Moin\mywiki".

Now you need to setup the 'mywiki' alias so that it will run Python to
interpret .cgi files. Right click on your new 'mywiki' alias and choose
Properties. On the first tab (Virtual Directory), click the
Configuration button. The first tab is the App Mappings tab, which
defines which programs to use for each file exetension. Click Add.
Browse to your python.exe (probably something like
c:\pythonXX\python.exe). Then add -u %s %s after the Python executable
path. The Executable line will look something like this:
C:\Python22\python.exe -u %s %s. In the Extension box enter .cgi with
the begining period. Confirm that the Check that file exists option is
not checked (if it is, MoinMoin won't be able to display sub pages).
Ok, you're done with the alias configuration, click OK several times to
get back out of all the dialog boxes. 
'''

...perhaps should have said something about setting about setting
Access Permissions, Write in particular, and perhaps Directory browsing
as well for the mywiki directory.

If the above is of any help, the cygwin diff should work, either placed
in your system path or explicitly pointed to in moin_config.py:
   external_diff = r'c:\Download\MoinMoin\diff.exe' 
However, I think a similar permission problem exists which needs
fixing.

HTH,
