You need to define .pl and .cgi files in the MIME TYPE Manager in IIS. There is a Thread in the Perl/CGI Forum that discusses how to do this.
BTW: On NT, I use the following Perl path (with the current build of Perl installed on the server) in all my executable .pl and .cgi scripts (not template .pl or html.pl files):
Also, I would recommend looking at the Microsoft Technet site for additional tips and suggestions for running Perl on Windows NT.
