I'm having trouble with SQL Server 2008 (Express with Advanced Services) Reporting Services permissions. I'm running this on Vista Ultimate at home - standalone machine with no servers, no domain or active directory.
When I go to the ReportServices site, I get this:
The permissions granted to user 'localmachine\Scott' are insufficient for performing this operation. (rsAccessDenied)
I don't remember having a problem at the office with SQL Standard on Windows 2008.
