I am in process of upgrading our existing projects from ASP.NET 3.5 to 4.0 and switching from Visual Studio 2008 to 2010. During this process I have had no trouble converting the projects and getting them to work in the development environment, but as soon as I put them into production, the RadToolBar will not update the other asp controls we have set up. No error is thrown. Nothing happens when the button is pushed. It is as if the button was not pushed at all. In ASP.NET 3.5, everything worked great. Our production server runs on Windows Server 2008 R2 Standard and we serve our internal websites through IIS 7. The website is created separately from other websites and is not stored in inetpub\wwwroot. It also runs on its own application pool. These websites are used internally and are set up to open in Internet Explorer 8 by simply typing the name of the web application into the URL. When the name of the application URL is entered along with the default page (e.g. "ThisProgramName/default.aspx"), all of a sudden everything works great. I want it set up so that including "default.aspx" in the URL is not necessary. Again, no settings have been changed in IIS 7 since the .NET 3.5 version of the web application was used other than the conversion to .NET 4. Also, when I feed the RadToolBar through RadAjaxManager I get the following error:
