Configuring Commerce Server 2007 with Host Headers and SSL
I had the pleasure recently of assisting a customer in setting up SSL on a Commerce Server 2007 site configured with Host Headers. Let me start by saying, it is NOT accomplished via the same approach as normal SSL certificate installation. This became apparent when the sites began shutting down and they were receiving the following error in event log:
Cannot register the URL prefix 'http://hostheader:443/' for site 'xxxxxxx'. The necessary network binding may already be in use. The site has been deactivated. The data field contains the error number.
The following the link directs you to a Technet article which explains in detail how to do this. Once they followed the article everything worked perfectly.

* If you tried it the traditional way first and had problems remember to remove those bad settings, or you will still have problems.
