I have installed a Live chat application which requires Asp.net 2.0 ( I am going to host it in house) and since all of my other websites use Asp.net 1.0, I upgraded .NET framework 1.0 to 2.0; but when I installed the chat software I am not able to reach its default page. I realize that in IIS 6.0 It is necessary that for each version of .net framework use a separate Application Pool so I created a new application pool for this Livechat website in IIS and assigned the website to it. I also made sure that in IIS Web Service Extensions, Asp.net 2.0 and 1.0 are allowed. I made sure that there is no app.offline.htm file exists in the file directory... This is the error that I get when I try to reach live chat default page: " The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /default.aspx " Please advise me...
