Hello
I have the same issues you had, did you ever solve the problem, and how do you know if .net framework 1.1 or 2.0 is installed and working?
I could find the asp tab when I went to ISS manager but I not sure what file/folder to click on and view the properties. Do you click on your sites folder or the actual .aspx doc and then view properties. I didn't see a asp.net tab on anything.
Any one else help?
