I want to configure reporting server on sql server 2008.I m using Windows 7 Operating System . I configure reporting manager using Reporting Services Configuration Manager and provide Service Account , Web Service Url, Execution Account and Report Manager Url setting .
But When i click on link of Report Server Web Service Url (http://udham-pc/TestReportServer), it ask for credentials I provide OS user credentials. Then it opens page with following error 
The permissions granted to user 'udham-PC\udham' are insufficient for performing this operation. (rsAccessDenied) Get Online Help And when I click the Report Manager URl(http://udham-pc/TestReports) , then it redirects to http://udham-pc/TestReports/Pages/Folder.aspx. But the page Opened is Only Having Header(On left side 
SQL Server Reporting Services Home and on right side of header three links
Home | My Subscriptions | Help ) no content on page.
I think i am missing some configuration. Please let me know. With prior thanks
