my dad made a website for his business a couple of years ago using publisher, and uploaed it to his webspace. However he didnt put the site onto a cd, and his pc fucked up, so he has lost it, but wants to update his site.

is it possible to download the whole site to edit it again in publisher or another program?

 

yes, ask the isp for FTP access and use a ftp program to download whats there.

Dreamweaver is the industry standard for editing HTML.

 

As above, the FTP site will have all the files used in the website
