While rendering the report (from Report Manager), you get the following error:

The selected report is not ready for viewing. The report is still being rendered or a report snapshot is not available. (rsReportNotReady)

In the report server logs, you will find the following:

w3wp!library!1!07/14/2008-18:33:46:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportNotReadyException: The selected report is not ready for viewing. The report is still being rendered or a report snapshot is not available., ;

This might have if you have recently repaired your .Net Framework. If you look at the Report Server Virtual Directory, you will find that you are able to browse through the reports but from Report Manager, you will get the above mentioned error. Make sure your Report Server database is accessible and there are no problems with IIS. Also, verify if you have the necessary permissions to view the reports. Check aspnet_isapi.dll mapping under Report Server Virtual Directory under inetmgr snap-in.

1. 1. Open inetmgr snap-in
2. 2. Browse to the ReportServer website under "Websites"-> "Properties"
3. 3. Click on "Virtual Directory" tab
4. 4. Click on "Configuration"
5. 5. Make sure the Wilcard Application Maps point to the right aspnet_isapi.dll (right .NET Framework version)
