Building a Certificate Authority in Windows Server 2019
Now available for download, the Building a Certificate Authority in Windows Server 2019 guide for creating a Two-Tier Certificate Authority using Active Directory Certificate Services.
This is a free download, and is available on Gumroad for distribution (enter $0 when checking out).
This guide is based on the Building a Certificate Authority in Windows Server 2019 guide series that I released in early 2020, as well as the Practical Guide to PKI with Windows Server book that I published in the fall of 2021.
The guide is a slight modification of the last chapter from the Practical Guide to PKI with Windows Server book, which demonstrates how to rapidly deploy a PKI using Active Directory Certificate Services. It does not add any additional functionality such as automatic deployment using Group Policy or configuring the Online Responder role, but those can be added in the future if needed.

- A guide for installing and configuring Active Directory Domain Services.

This guide is meant for developers, network administrators and systems administrators who have a basic understanding of Windows Server and Public Key Infrastructures and need to deploy a Certificate Authority rapidly within their environment for various purposes.
