Error "The permissions granted to user '
\IUSR_ ' are insufficient in Reporting Server
If you get this error "The permissions granted to user '
\IUSR_ ' are insufficient for performing this operation." when you work with Reporting Server, it is because the reporting server's virtual directories under IIS is running in 'Annonymous Mode'. To fix this open IIS, right click on the virtual directory that your report server uses, click on the tab 'Directory Settings' and click edit under 'Authentication and Access Control' and untick the 'Enable Anonymous Access'.
