SSRS for some reason not shown in the event viewer, stopped working over the weekend. There was a MS Office uninstall/reinstall done on Friday. As of today morning, we started seeing 404 errors when connecting via a web browser. In IIS Manager I had to set ASP.NET v4.0 to Allow. The error now reads "Could not find permission set named ASP.Net" Any ideas? - Vimal

Here is the respective error in the event viewer. Event code: 3008 Event message: A configuration error has occurred.

Hi Vimal, Open Reporting Services configuration manager and check if any settings are not configured, especially in the "Web Services Identity" page. If they are all right, if possible, post the web.config content of your report server, which is default stored at C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer. thanks, Jerry
