Great question, Jeff, and I apprecitate that you spent some time thinking about my propblem.
A few weeks ago I took a course in dynamic web sites using Dreamweaver. As a result I have many .asp files that worked on the IIS on the classroom computer. After I followed the instructions to set up IIS on my own computer, I loaded some of these files into Dreamweaver and hit F12 to view them on the testing server. When I did this, instead of seeing the proper rendering of the .asp code, I got a "cannot display" error message. This led me to yesterday's post on this board.
Thanks for any insight you might have, Jeff.
