🏢 Small Business Network Infrastructure (GNS3 + Windows Server)

📘 Project Overview

This project simulates a small business network designed and implemented in GNS3.
The goal is to demonstrate practical skills in network design, VLAN segmentation, inter-VLAN routing, and Windows Server administration.

The simulated environment includes multiple VLANs for different departments, a central router performing inter-VLAN routing (Router-on-a-Stick), and a Windows Server configured with Active Directory, DNS, and DHCP.
