SSL for Administration Web Site

I am trying to use the integrated Administration Web Site with IIS 5.0 on Windows 2000 Server through a secure connection. I have installed a Certificate for the web site and now I have to access it through “https://computer” but whenever I log on,I still get the message that I’m not connected through a secure connection. Has anyone had this problem or know anyway to fix it or am I really connected through a secure connection? Thanks, Jeremy Whitlock
