The problem you're encountering is due to UAC (user access control). Even though you're setup as an adminstrator you're account is not being treated as such unless you run IE as an Administrator.
To save having to remember this step each time, and to enable other browsers to be used and Visual Studio to deploy reports you need to setup your login as an explicit user to SSRS Server. Follow the steps below and that should do the trick.
Steps recommend using IE - other browsers can work with the following steps but not guaranteed.
- Open Internet Explorer as Administrator(Right click the IE exe and
choose “Run as Administrator”
- Go to the “SQL Server Reporting Services” Home page (
http://localhost:port/Reports) which will redirect to http://localhost:port/Reports/Pages/Folder.aspx
- Click on the “Folder Settings” button.
- Click on the “New Role Assignment” button.
- Add the Group or user name: DOMAIN\USER_NAME or in this case LOCALMACHINE\USER_NAME. You'll probably want to pick Content Manager role so your account has full functionality.
Hopefully the above will do the trick.
