Technical Information (for support personnel) Background:
This error indicates that the page you are trying to access is secured with Secure Sockets Layer (SSL).
This problem occurs because the HTMLA Administration forms do not check to see if an SSL certificate is assigned, or bound, to the Web site before it permits the Require a secure channel (SSL) option to be enabled.
If you want to use SSL, you can install a certificate on the site. For more information about how to install a certificate on the site, click the following article number to view the article in the Microsoft Knowledge Base:
