Context

As part of a project involving three Formula 1 teams (Mercedes, McLaren, and Aston Martin), the objective was to pool technical data to enhance engine performance. Each team set up a similar IT infrastructure but with its own specificities and dedicated domain.

My role focused on the McLaren infrastructure, which was designed to host network monitoring tools, data backup solutions, an incident management system, and IP telephony. The entire environment was virtualized using Proxmox on HP server hardware.

To manage this organization, I implemented a central directory service based on Windows Server 2022. This involved creating a forest and a domain, as well as managing the internal DNS to ensure proper resolution for all McLaren services.

High availability and fault tolerance were key requirements for this infrastructure. To achieve this, I configured a second Windows Server 2022 and set up Active Directory and DNS replication between the two domain controllers.

Goals

Installation and promotion of Windows Server 2022 as a Domain Controller.
Configuration of Active Directory (OUs, Groups, and Users) and DNS services.
Implementation of secure file sharing via SMB with specific access permissions.
Deployment of Group Policy Objects (GPOs) for automated client configuration.
Ensuring service continuity through Active Directory and DNS redundancy.

Skills

Managing IT assets.
Responding to incidents and requests for assistance or evolution.
Working in project mode.
Providing an IT service to users.
