I have a new computer with explorer 9 and I have a cac card reader. I can not log into any websites with the cac reader. I pick a certificate and put in my pin, and then it just says can not display website. I have tried everything and brought the laptop into the IT guys at my command and no one has a clue. I have reloaded the software and cleared caches put the tsl etc......... The "experts" at work know much more than me and it baffles them. They said it is probably a setting!?!!? But which setting, where? No one knows.
The reader and software work fine on my old computer with explorer 8. Both computers are HP and my new one has windows 7 if that matters.
