Problem with creating site server signing certificate template

I have Windows 2008 installed in my system and i have created a certificate but when i am clicking on the link to request the site server for signing the certificate than i am getting an message saying "In order to complete certificate enrollment, the website for the CA must be configured to use HTTPS authentication" If i click on click on Ok than i don't see the certificate template. I haven't created a certificate earlier and this is my first time so i am not sure if i am missing out anything. Is there anyone who has experience in in creating certificate and getting it signed form site server??? I really need help on this.

I am not sure but it seems as if there is something wrong with your server. I have checked about the error you are getting and i have come across many people who have faced same error. Most of them had mentioned that reinstalling server from scratch had helped them out. So you you don't mind try that, than go ahead with it and let me know if it works out for you as well.
