Only http is accessing site not www

[guy77]

I have setup xampp on my vista box and I am using something called dyndns updater to forward calls to my website to my xampp server.

The site works fine and people are able to access it using http://guy77.dyndns.biz but if they try typing www.guy77.dyndns.biz they get a 400 error and the site does not load.

Thanks in advance

http://guy77.dyndns.biz is the address given to you by Dynds and the one to use. I have a similar one which also does not have http://WWW.---.
