The first step in certificate generation and replacement is setting up a Microsoft Certificate Authority template through a Remote Desktop Protocol session. After you have created the new template, you add it to the certificate templates of the Microsoft CA.

About this task

Prerequisites

This VMware Validated Design sets the CA up on both Active Directory (AD) servers: the main domain dc01rpl.rainpole.local (root CA) and the Region B subdomain dc51lax.lax01.rainpole.local (the intermediate CA). Both AD servers are running the Microsoft Windows Server 2012 R2 operating system.

  • Verify that you installed Microsoft Server 2012 R2 with Active Directory Domain Services enabled.

  • Verify that The Certificate Authority Service role and the Certificate Authority Web Enrolment role is installed and configured on the Active Directory Server.

  • Verify that dc51lax.lax01.rainpole.local has been set up to be the intermediate CA of the root CA dc01rpl.rainpole.local.
