hmm , i am gonna try and go over all the problems tht might be behind the page not getting displayed :
1. Is PWS installed correctly , chk by putting a index.html file in c:\inetpub\wwwroot directory (assuming PWS is installed in c

and then type
http://127.0.0.1 in ur browser
2. have u saved the file in right directory i.e. in c:\inetpub\wwwroot
3. Try and writing a small program in notepad first , dreamweaver can be using ASP features not supported by PWS (a hello world will do)
4. just check if PWS service is started or stopped
When i started ASP , it was usually a stupid sounding mistake whcih caused the ASP file not to run :P
