The exact error message is: Internet Explorer cannot download Cassini.exe from www.asp.net Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. Now what is really odd, is I have tried to download this file, on a number of occasions over the last month or so... and it has not worked.. Is there any alternative download location at all ? (Or can somebody mail me the source code ?) D
