How to Enable SSL Protocol (5 Steps)

Click the Windows 'Start' button and select 'Control Panel.' Double-click 'Administrative Tasks' and then click the 'Internet Information Services (IIS)' icon. This opens the configuration window.
Right-click the website you want to edit on the left side of the window pane. Select 'Properties' to open the configuration window for the website.
Click the 'Website' tab. In the section labeled 'Web Site Identification,' verify that the port enabled is '443'; 443 is the default number for SSL-secured sites.
Click the 'Advanced' button. In the window that opens, look in the section labeled 'Multiple SSL Identities for this Web Site.' If port 443 is not displayed, click the 'Add' button and enter 443 in the text box labeled 'SSL Port.' Click the 'OK' button.
Click the 'Directory Security' tab. Select a directory on the website and click the 'Edit' button. Check the box labeled 'Require Secure Channel (SSL).' Click the 'OK' button. SSL is now enabled on the server.
