So you host a bunch of internal SharePoint sites, Websites and other internal web applications. You want to secure them with SSL but you cannot afford a certificate from a third party certificate authority right now. I am going to walk you through installing a new CA, request a certificate, approve a certificate and then install a certificate.
Go to start and click on “Server Manager”
Click on “Add Roles”
Select “Certificate Services” and click next
I typically choose “Certification Authority” and “Certification Authority Web Enrollment” and click next
NOTE: I choose the web enrollment so I can request certificates and download them from the web browser.
