Thanks; got a reply in another forum that suggested the same resolution, and it worked. Seems simple once you find the answer. Thanks for your input.

Hello folks, I am a new ReadyNAS DUO user and am having same problem using Windows Vista with IE8. I cannot add the certificate to the trusted certificates zone because when I click on the red certificate error bar and it shows the certificate details, all the options to perform any actions on it are greyed out! All I can do is view the info on the certificate, but nothing I see allows me to click "add" certificate to be trusted. The certificate name is simply the ip address of my ReadyNAS DUO unit. Should I rename and regenerate the certificate with a text name of say my registered dynorg.org hostname? Or is there a way to import the certificate from the ReadyNAS DUO? Where is the generated certificate stored such that I can point IE8 browser there to fetch it and install it into the trusted certificates zone?
