Apache2 SSL config problem

I'm building a new server (mandrake) with the intentions of moving my
current webserver on to the new server. I've installed the base
packages (rpm's) on the new server and apache is now running. Then I
copied over my httpd.conf, httpd2.conf, commonhttpd.conf and Vhosts.conf
files from my old server to the new and restarted apache. It's live and
running. I'm running apache2 on both systems.

However, when I access anything on the new server I get a 400 error/Bad
Request telling me to try accessing the site using https.

It seems apache is forcing all of my web requests to be ssl.

I'm guessing there's a module configuration error or similiar that I've
not copied over from the old to new server but I admit to being a bit
lost on what to try. Any suggestions for me?

Thanks in advance.
