Trying to go though a teach yourself book, but stuck on chapter 3! The setup asks to setup the Local info and testing server for a new site (local/network, details setup automatically).
Dreamweaver automatically puts in URL Prefix as Macintosh HD/

All fine, until I try to preview any page, even one with just simple text. I get the message:
<b>Safari can’t open the page “macintosh%20hd/work_page.html” because it can’t find the server “macintosh%20hd”.</b>

This is driving me mad, as it's a fresh installation of osx. Any help would be GREATLY appreciated!
