I think the question says it all, however:
Using Internet Explorer 8 on Windows 7, when I browse to an internal secured domain (https://...) at work, the certificate is showing as untrusted as it's an internally generated certificate.
Internet Explorer initially blocks me from going to the site. I can continue on to view the site and it shows the address bar in red. When I close the browser and return to the site I have to go through the process again. I'd like to know the proper steps to install the certificate so that it will not show as untrusted any longer.
