Newbie Sharepoint Access Denied on default application

I'm learning Sharepoint. I am able to surf to an log in to the admin page. I try to surf to the default site (port 80) and I am prompted for a login. I login as the administrator, but I get access denied. Wouldn't the administrator have access to ALL sites automatically? This does not seem to be the case, but I cannot find where to grant access开发者_C百科 to the admin to this site.

Is this not clear or too complicated to easily answer. Any guidance, where to look?

i found an area in the admin area to allow public access, and that seemed to work
