Assignment 1: Setup of Essential Services for GT7 Network - Report

This report details the network engineering and setup of essential services for the small business organization GT7. It begins with the network design, including a WAN network with branches in Gold Coast and Brisbane connected to headquarters via VPNs. The report then covers the setup of an Active Directory domain controller, including organizational units, user groups, and user management. Following this, the implementation of DNS and DHCP is explained, along with their integration with the domain controller. The report also demonstrates the backup of DHCP configurations and concludes with the setup of an IIS web server and its integration with the headquarters. The report emphasizes the importance of network design, administration, and engineering for operational effectiveness, and also covers IP allocation, DNS SOA, DNS records, and DHCP scopes.

Abstract
Several researches has time and again proved the importance of Network design,
administration and engineering in the operating effectiveness of the network. The following
report studies such a network engineering for the small business organization GT7. First the
report, presents the network design of this organization and provides explanation of the
resultant WAN network. Then the report presents the setup of the active directory domain
controller and discusses the organizational units as well as the user groups and the involved
users. After this the report implements the DNS and DHCP setup and explains the mapping
with the domain controller. Next the report shows the backup of the DHCP configuration
taken thereafter. Then the report shows the setup of the IIS web server and its mapping with
the headquarters of GT7 and ends with concluding notes.

Introduction
The following report aims to highlight the importance of Network design, administration and
engineering in the operating effectiveness of the network. The report studies such a network
engineering for the small business organization GT7. The report begins by presenting the
network design of this organization and provides explanation of the resultant WAN network.
Then the report presents the setup of the active directory domain controller and discusses the
organizational units as well as the user groups and the involved users. After this the report
implements the DNS and DHCP setup and explains the mapping with the domain controller.
Next the report shows the backup of the DHCP configuration taken thereafter. Then the
report shows the setup of the IIS web server and its mapping with the headquarters of GT7
and ends with concluding notes.

Figure 1: Network logical diagram
The above network topology diagram shows the overall network setup of the two branches as
well as the headquarters of the company. The branches at Goldcoast and Brisbane are
securely connected with each other and the headquarters over the internet through site to site
IPsec VPNs enabled in each of the routers. The branch at Goldcoast consists of 10 servers as
well as 10 sets of workstations and IP phones for the 10 different employees. The 10 servers
include file server, email server, print server, DNS server, DHCP server, domain controller
and the Sharepoint server. The branch at Brisbane consists of 3 servers namely the domain
controller, the DHCP and the application server. The branch also consists of 6 sets of
workstations and IP phones for the 6 different employees. Thus the two branches of
Goldcoast and Brisbane along with the Headquarters form the complete site to site WAN
network of the small business organization GT7 through the ISP or the Internet Service
Provider. Before the network reaches or is forwarded by the ISP the VPN tunnelling and
NAT configurations specify the path of network access thus securing and isolating
communication only within the company offices and thereby mitigating the external security
threats like hackers, malwares and worms.

Task 2: Essential services for internet
Task 2 Part A: Setup of Domain Controller, DNS Server and DHCP Server
Domain Controller
The active directory domain controller created for the network is patel.com. The domain
controller further creates organizational units for specifying the different users present along
with their respective user groups.
Organizational Unit GT7
User Groups: General employees, network administrators, branch manager
Users: A total of six users have been shown in the following demonstration. These include
two users from each of the three user groups.

SETUP ESSENTIAL SERVICES
As can be noted from the above screenshot, the scope of operations and security
privileges of the three different user groups are specified accordingly. Both the branch
managers and the employees have local domain distribution levels.

Enabling ICMP echo messages using group policy
The above screenshot shows the group policy changes that are required to be made in the
windows firewall exceptions for allowing ICMP ping messages. Next the group policy
settings need to be updated in the command prompt for the domain controller in the virtual
machine.
