💼 About Me

I’m an IT Support-focused professional with hands-on experience working with Active Directory, Microsoft 365, and Windows environments.

I enjoy troubleshooting technical issues, identifying root causes, and helping users get back to work quickly.

This portfolio highlights the real-world support scenarios I’ve worked through while building practical, job-ready experience.

IT Support Portfolio – Active Directory, Microsoft 365 & Networking

This repository showcases the hands-on labs and support scenarios I’ve worked through while practicing real IT support tasks.

The focus here isn’t just on setting things up — it’s about troubleshooting issues the way they happen in real environments: understanding the problem, identifying the root cause, and resolving it properly.


Overview

This portfolio reflects the kind of day-to-day work handled in IT Support roles, including:

  • Supporting users with login and access issues
  • Managing accounts in Active Directory and Microsoft 365
  • Troubleshooting Windows system problems
  • Investigating network issues (DNS, connectivity, access)
  • Resolving real-world scenarios like shared folder access, slow systems, and update failures

Each lab is structured like a real support ticket — starting from the user’s issue through to investigation, root cause, and resolution.


🖥️ Lab Environment

To simulate a realistic working environment, I built a small lab using:

  • Windows Server (Domain Controller with Active Directory & DNS)
  • Windows client machine (user workstation simulation)
  • Ubuntu Linux server
  • VirtualBox internal network

This setup allows me to test how users, systems, and network services interact in a controlled environment.


🧑‍💻 Skills Practiced

Across these labs, I’ve worked on:

  • Managing users, groups, and access in Active Directory
  • Handling Microsoft 365 user accounts, licensing, and mailbox issues
  • Troubleshooting Windows systems (performance, updates, malware)
  • Diagnosing network issues (DNS, DHCP, VPN, connectivity problems)
  • Configuring Group Policy for drive mapping and access control
  • Investigating Exchange Online and Outlook-related issues
  • Testing basic Linux integration within an Active Directory environment
  • Following a structured approach to troubleshooting and incident handling
  • Using PowerShell and Python for simple automation tasks

🔍 Example Scenarios

Some of the real-world issues I worked through include:

  • User unable to log in to the domain
  • Shared folder showing “Access Denied”
  • Microsoft 365 login or mailbox issues
  • DNS not resolving internal resources
  • VPN connected but no access to internal systems
  • Windows Update failing to install
  • Slow system performance
  • Malware detection and cleanup

⚙️ How I Approach Problems

For each issue, I follow a simple and consistent process:

  1. Understand what the user is experiencing
  2. Check the basics (connectivity, system status)
  3. Investigate configurations and settings
  4. Identify the root cause
  5. Apply a fix
  6. Verify everything is working as expected

🎯 Purpose

I built this portfolio to practice working like an IT Support professional.

Instead of just learning concepts, I focused on:

  • Solving real scenarios step by step
  • Understanding why issues happen
  • Documenting the troubleshooting process clearly
  • Building confidence in handling real support tasks

🚀 Where to Start

If you're reviewing this portfolio for IT Support or Junior SysAdmin roles, these are good starting points:

  • Active Directory File Server Access Troubleshooting
  • Microsoft 365 Identity Lifecycle Automation
  • DNS Resolution Failure in Active Directory
  • DHCP IP Assignment Issue
  • Exchange Online Incident Investigation
  • Python Automation for IT Support Tasks
