I'm having this problem on a new cruisecontrol.net install running on Windows Server 2003 where I cannot browse to http://localhost/ccnet/default.aspx.
I can, however, browse/open .html files, just not .aspx pages.
The errors I get when trying to access .aspx pages are:
In IE: "Internet Explorer cannot display the web page".
In Chrome: "Error 101: ERR_CONNECTION_RESET".
I've done the aspnet_regiis thing and double-checked my web extensions. Web extensions show as "ASP.NET 1.1.4322" and "ASP.NET 2.0.50727", both set to "Allowed".
Any ideas?
