Hey guys

Been on holiday now for 4 weeks a quite bored.
Decided to make a website on Dreamweaver CS3.
Uploaded site to FTP server for testing, and all should work, well it doesnt.
I uploaded the files to public_html folder.
But when I type domain name www.example.com it only brings up the index with all folders.
When I type in www.example.com/index.html the site opens correctly.
Did I miss/delete something, what am I missing.
Spent the whole morning googling the prob but with no luck.
Web design and what not is totaly new to me.

PLease help

Thanks in advance
