IIS 7: SSL binding getting lost/Deleted unexpectedly

On the IIS 7 sometime you would find the SSL binding for the website has been deleted and not replaced, or has been deleted and replaced with invalid certificate info.  The problem occurs because of a legacy SSL certificate hash property interfering with the current SSL binding, resulting in the correct binding being deleted.

And sometime  following entry is logged in the event viewer
