The permissions granted to user are insufficient for performing this operation. (rsAccessDenied)

Go to My Computer, Right click and get the User Management by clicking Manage. See the Users in the Machine. Right Click on the IUSR_MACHINENAME and view the Properties. Get the “Member Of” tab and add “Administrators” group in the Members List.

Now browse http://Server Name or IP/Reports/ (Report Browsers)
http://Server Name or IP/ReportServer (Report Manager)

Works fine !

Microsoft.ReportingServices.RsProxy.AccessDeniedException

I Came across this error message (Exception of type 'Microsoft.ReportingServices.RsProxy.AccessDeniedException' was thrown. ) today whilst installing SQL Server 2005 Reporting Services on a windows 2003 server

thought i'd share the answer for anybody else search as there wasn't much on the Internet for it.

To fix the issue I followed these steps :-

Go to Report Manager
Select Site Settings from the top right menu
Select Configure item-level role definitions
Select Content Manager
make sure all the tick boxes are ticked
For myself the Manage / View models tickboxes were not ticked and this fixed the issue

Hope this helps you out.
