But when I tried to browse a "hello world" .aspx I was getting this "access denied." So I suppose somewhere (and this is what I am trying to find out) in the Server 2008 IIS there has to be a setting to allow .aspx page to be loaded. Or my appl. I will keep looking. Thank you.

Do you have access to IIS manager on the target server ?
What version of IIS (I assume IIS 7) ?
