Install Certificate Authority

In this blog I will describe the installation of Microsoft Certificate Authority. This installation/screenshots are based on an Windows 2012R2 server. The Certificate Authority will be installed a lot in the future I guess because you can’t request public certificates with an internal server name anymore with an expire date after the 1st of November 2015. Especially Microsoft Exchange Servers are using certificates with internal server names configured.
