Firstly I need to clarify that this is applicable to xampp installed on my computer as a test server
The "configuration.php" is a file in c:\xampp\htdocs\MyWebsite.com controling the Joomla settings.
I changed PWs to get to the state I am right now.
Every thing works fine - access to Joomla back end, etc.
I have all functions operational - including preview as default showing the Home Page.
However, I cannot preview other pages after clicking on any link
because the "Authentication Required box" appears as described in my first post.

You are right except that I have backups and my site is live on external server.
