Assuming EI is Internet Explorer, it's not a "problem" but a MS security measure. One way to shut IE 7 up, is to proceed with "Continue to this website (not recommended)." Then click the Certificate Error button next to the URL, and select the "View certificates" option. It'll offer the option to "Install Certificates". Once that's done, IE should be muted, as long as you access the LMS host via the same hostname as on the SSL certificate. For example, the LMS hostname I entered during certificate generation was "nms", not the alias "cwk" or "nms.fqdn.com". Trying the latter two would continue to result in that IE certificate warning.
