Reporting Services privileges

How do I need to setup IIS and SQL Server to get reporting services to work? When I navigate to http://<my server>/reports, I get a generic error page. PLease help!

More info: When I click "Set SharePoint administration group" from the SharePoint Central Administration page, I get the following:

"Cannot connect to the configuration database. For tips on troubleshooting this error, search for article 823287 in the Microsoft Knowledge Base at http://support.microsoft.com"

The info in this KB article did not help.
