    Enable directory browsing for PKI troubleshooting and certificate distribution in IIS. Enable delta CRL distribution by configuring double escaping and test with a DNS alias.

  • Offline Root CA Environment Preparation and Security6:32

    Deploys a secure offline root CA as the trust anchor for a PKI hierarchy, with air-gap isolation, security hardening, auditing, and proper authority information access and CRL distribution points.

  • One Certificate Server or Two? Planning the Company PKI
  • CA Policy File Configuration and Security Parameters7:27

    Define and configure a CA policy file before installing, embedding policy, OID, and notice text; set cert service server parameters, renewal settings, and key usage for server and client authentication.

  • Quiz: PKI web distribution point, root CA VM and CAPolicy.inf
  • Root Certificate Authority Installation and Setup4:25

    Install the core certificate services, configure a standalone root CA with a new private key (4096-bit, 256 hash) and 20-year validity, following CDP guidelines avoiding delta CRLs.

  • Root CA CDP Configuration and Local Filesystem Setup9:36

    optimize root ca settings by removing default CDP entries and configuring two custom CDP entries: a local file system entry for CRL generation and an HTTP distribution entry for offline root CA.

  • Authority Information Access Configuration for Root CA3:39

    Configure authority information access for the root CA by adding a custom AA entry that directs clients to download the root certificate from the web server for chain building.

  • Quiz: Root CA extensions - CDP entries, AIA and checking them
  • PKI File Transfer Using Air-Gapped Security Methods2:52

    Use air-gapped security to move PKI files, bringing an external drive online and copying the root certificate and CRL from the system32 sort SVR folder, then power off.

  • Enterprise CA Policy Configuration and Prerequisites4:14

    Deploy an enterprise issuing CA with Active Directory Certificate Services on Windows Server 2025. Create a CA policy INF to enforce 1496-bit renewal keys, ten-year renewals, and zero default templates.

  • Root CA Certificate and CRL Publishing Methods6:58

    Publish your root CA certificate and CRL to Active Directory, the PKI web server, and the local certificate store to establish a trusted PKI infrastructure for clients.

  • Quiz: Moving root CA files, why two tiers, and keeping the root CRL fresh
  • Enterprise CA Installation and Certificate Request Process5:52

    Install and configure enterprise certificate services, add the Certificate Authority and Web Enrollment roles, enable dependencies, and generate a certificate request for a subordinate CA signed by the root CA.

  • Root CA Certificate Request Processing and Signing5:55

    Transfer certificate requests securely to the offline root ca via removable media in a two-tier pki setup, then sign and retrieve the issued certificate.

  • Enterprise CA Certificate Installation and Final Setup7:24

    Install and activate the enterprise certificate authority, then configure CRL and AIA/CDP extensions to support certificate issuance and chain validation.

  • Quiz: Enterprise issuing CA - request, install and first steps
  • The Lab Environment Overview3:37

    Build a PKI infrastructure using Windows Server Core in a Hyper-V lab, deploying DC1, an offline root CA, and an issuing CA for the learned lessons.com domain via PowerShell Direct.

  • Building a PKI infrastructure lab on Windows Server Core VMs. Part 113:55

    Build a PKI infrastructure lab on Windows Server Core VMs by provisioning an offline root CA, configuring CRL and AIA, installing AD CS, and validating DNS integration.

  • Building a PKI infrastructure lab on Windows Server Core VMs. Part 216:23

    Build and configure a PKI lab on Windows Server Core, deploying an enterprise subordinate CA with Active Directory Certificate Services, and validate CRL, CDP, and AIA settings.

  • Section Quiz: Building a PKI infrastructure lab on Windows Server Core VMs
  • Run a Two-Tier PKI from the Command Line: Check, Tune, Revoke, Publish

Description

Certificates protect almost everything in a Windows network: web servers, VPN, Wi-Fi, smart cards and signed scripts. They come from your own Active Directory Certificate Services (AD CS) public key infrastructure, and the safest way to learn it is to build one. This course builds a working PKI lab with you, step by step.

How the course works

You build the lab first: domain controller, member servers and the certification authorities, all on Windows Server 2025. Every lecture shows the actual console or PowerShell window, so you can pause and repeat each step on your own machine. Two practice tests at the end check what you learned.

Inside the course

  • Building the Windows Server 2025 PKI and Active Directory lab: virtual machines, the domain, and the servers the PKI needs.
  • A PKI lab on Windows Server Core: certification authorities without a desktop, managed remotely.
  • Practice tests: 59 questions on PKI configuration and on deploying and managing AD CS.

A practical example

A typical task: your web servers need trusted certificates that renew themselves. With an issuing CA in the domain and the right template, every server can request its certificate automatically - and the lab is where you try that safely before you touch production.

The course runs about 2.5 hours in 23 lectures. It assumes basic Windows Server and Active Directory skills and focuses on building and running AD CS; it is not a cryptography theory course.

Who this course is for:

  • Windows Server administrators who must run an internal PKI
  • Active Directory administrators new to certificates and AD CS
  • Security engineers who want a safe PKI lab to experiment in
  • IT students preparing for Windows Server identity and security roles
