Could not load file or assembly Microsoft.ReportingServices.ProcessingCore or one of its depende

My reporting server 2005 frequently throws error below.

The PC hosting reporting server has .net framework 1.1 and 2.0 installed, and it does not have SQL server installed. The 2 databases used by reporting server are in another PC.

Please help.

Hi Weo,

I also have the same error as you...then I gave machine asp.net user the full rights on folders C:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\ReportSerever and Reports. And Then It works fine on my Reporting server..

Regards,

Balwant Patel.
