In short:<\/strong> To install an SSL certificate on Windows Server (IIS), create a CSR in IIS Manager<\/strong>, send it to the certificate authority, install the issued certificate with Complete Certificate Request<\/strong>, add intermediates and create an HTTPS binding on port 443<\/strong>. Because maximum certificate lifetimes shrink from 2026, automated renewal is recommended. We do all of this for you via remote desktop.<\/div>\n
