When I run the Admin module, the browser interface brings up what looks like a malformed URL:
http://zntiis2/perl/bin/texis.exe/Webinator/dowalk, which cannot run.
I would expect to see something more like:
http://zntiis2/perl/bin/texis.exe "Webinator dowalk"
In the Home Directory tab of the default web site properties, I have given execute permissions of Scripts and Executables, and have given both read and write access (which IIS 5 cautions against).
