In a fresh install of SharePoint 2010, I naively built a site without first creating a site collection to put it in. The site sites in the root of the server's URL space (i.e. it is simply http://sharepoint.mycompany.com).
Having realised this is not the best idea in the world I want to delete it.
I am logged into the server as a user that has 'Full Control' but I find that when I attempt to delete the site via 'Site Actions'->'Site Settings'->'Delete This Site' I get:
Error: Access Denied Current User You are currently signed in as: SGC\sgcadmin Sign in as a different user
In Sharepoint Designer, logged in as the same user, the Delete button is greyed out.
Note that I can delete sites made by the same user within site collections.
What am I missing? Where should I look now to try to better understand what permission(s) is/are missing?
