File properties not showing on list of files when director..

Hello.
I was wondering how I can get the webserver to show the file information on the files listed in a browser,
when examining a webfolder that has directory browsing enabled. I can only see the filenames without the extension
and nothing else. What am I missing?

The server-machine is used for demos and runs on windows 2000 Professional with IIS 5.0

Thanks
