IIS 6 Problems with Exchnage Server 2003

OK, so I should have posted this a while ago but time has run away from me, I have a Server 2003 running Exchange Server 2003.

On the Server and Exchange side of things are running fine but when it comes to IIS6 where I have setup SSL for OWA, now that I am using the server as a web server need to add the ?s? to http:// is a pain.

What I?d like to do is disable SSL on http://domain.com but keep it on http://domain.com/exchange/ is there a way to do this without needed to instill CA?

After searching the net I have yet to find a way.
