Hi, I just setup our fc3 system to service https only (port 443), no http. When I check it in IE, I got Security Alert: Information you exchange with this site cannot be viewed of changed by others. However, there is a problem with the site's security certificate. ... Do you want to proceed? If I click Yes, I can browse my web site. Then, during this session, everything looks okay. If I open another browser, it will repeat the above. That is okay with me althouhg not perfect. However, I face a problem when I use Firefox. I got: You have received an invalid certificate. Please contact the server administator or email correspodent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Then, there is no option to Continue. I can only click OK, and my web site does not show up. What does that mean -- "the same serial number as another certificate..."? Where to get a new certificate containing a unique serial number? I apprecaite your help! Hongwei Li
