If you are a local admin on the box, you should have access to the admin website (and the reports home page, for that matter). Also, just to make sure, make your windows authenticated username an SA on SQL Server.

The URL for the admin page should be of the format http://<servername&gt;:80/Reports.

If you are using a named instance, put the named instance with a underscore after Reports, like

http://<servername&gt;:80/Reports_instancename

Once you can connect to the admin website, you should be able to set the needed users to have access to the home page.
