This item provides a more detailed explanation of the above
procedure for NT systems.  Before you install MailMan on an
NT system, make sure that you have Perl 5 installed.  For
more information on where to get Perl 5 and how to install
and configure it for NT, please consult Evangelo Prodromou‘s
Perl for Win32 FAQ at

1.   Copy the distribution to the location that you want to
  unpack it in.  “/public_html/mailman/” in the above example.
2.   Unpack the distribution.
3.   If you are using IIS, make sure that the directory
  where your MailMan installation resides is marked executable
  in the IIS administration interface.  Also make sure that
  your “mailman.pl” file ends in an extension that will be
  recognized by your system as a Perl 5 script.  Most of the
  time “mailman.pl” will do the trick, but your installation
  of Perl 5 may be different.

Check your installation by loading “mailman.pl” in your web
browser through your web server.  In the above example, the
URL to access MailMan would likely be
<URL:http://yourserver/mailman/mailman.pl>.
