System Administration and LAN Management Report - BN206, T1 2018

This report outlines the development and implementation of a Local Area Network (LAN) for a company named "Groovy Movie," an entertainment business renting CDs and DVDs. The report details the planning and hardware selection, focusing on cost-effectiveness, mobility, and security. It covers authentication techniques using Active Directory Domain Services (ADDS), DHCP configuration for IP address management, and the setup of an IIS server within the LAN. Furthermore, the report describes the administrative domain's role in controlling network systems and enforcing security policies. Functional needs like connecting wires, computers, and switches, as well as non-functional requirements that enhance system quality, are discussed. The network design, created using Visio software, includes considerations for connecting wires, computers, and switches, with switches being a critical element. The report concludes by summarizing the LAN's design, incorporating administrator and user domains, authentication, dynamic host configuration, and the use of an ISS server for host configuration across three departments: customer service, finance, and inventory.

1. Overview
In Perth there is a company and its name was “Groovy Movie”. They do business in
entertainment field. They rents out the CD or DVD that contains the movies or popular TV
shows. As like all company they also have various subdivisions. They are Consumer services,
Finance, and Inventory. The overall strength of the company was 50 members. The CEO of the
company decided to implement the LAN for enriching their potential. Because that improves the
effectiveness of communication as well as data sharing among the various departments. For this
purpose they need a no of domain systems based on the Windows server-OS. Here we would see
about the implementation of LAN.
2. Development of the LAN
The LAN that must have the mobility. Because that is the very important requirement of
the company. The system must be cost effective. The LAN system that must contains the
effective information sharing technologies. The security was also very essential in the required
LAN. So the LAN design was created by these considerations [1].
In LAN there are two most common technologies are followed. Each has its own
advantages as well as dis advantage. They are Wired LAN and Wireless LAN. Wired LAN was
most widely used for so far. Wired LAN system uses the RJ-45 fiber cable for the data sharing
purpose. So this kind of network was called as RJ-45 Network system. For our requirement the
most suited technology was wired LAN. That would be demonstrated in the clients company.
3. Requirement Planning.
The main part of the network design involves the selection of appropriate hardware.
Because that verify the success of the plan. For our design need we need to select the best suited
hardware. Ethernet adapters was the first and foremost need for the network development. After
that we need switches for connecting systems. That acts likes a bridge between the computers.
That is responsible for sharing the data between the computers. And also the RJ-45 cables are
required for the system development [2] [3].
4. Authentication techniques
Active Directory Domain Services (ADDS) is used for user authentication. One main
domain is setup with the help of one Windows server 2016 based domain controller. The main
domain (Parent domain name) selected is groovimovies.com. Users are in a child domain called
users.groovimovies.om. Child domain is setup with the help of one Windows server 2016 based

domain controller. One client machine is setup and client OS is installed. This client machine
represents the end users computer [2].
OS structure is used to separate each department users. Three Ous will be setup. i.e : Inventory,
Finance and Customer Service. Users of the same department will be added in their respective
OUs.
Parent-Child trust will be implicitely established. It is a two way transitive trust.
5. DHCP configuration
One Windows Server 2016 based server will be selected as a DHCP server. Except main
domain controller other servers and end users will get IPs from the DHCP Server.
Following configuration can be used
Main Domain Controller : 192.168.1.1 / 24 ( Static IP)
DNS Server : 192.168.1.2 / 24 (Static IP)
DHCP Server : 192.168.1.3 / 24 (Static IP)
Scope-1 : 192.168.1.10 / 24 to 192.168.1.100 / 24
Scope-1 IPs will be automaticaly used by child domain controller and all other domain
computers.
Here the step by step process of DHCP configuration was showed below. The below
showed screen shots allow higher understanding of the concepts.

6. IIS server in LAN
One Windows Server 2016 based server will be selected as a web server and IIS server
will be installed. Groovimovies.com domain can be used in the internet. The home directory files
for this website will be stored in the webserver. Usually the webservers will be kept in De-
Militarized zone. One firewall will be introduced between outside network and inside network.
Then web server will be connected in the DMZ zone. All the public facing servers will be in the
DMZ zone [4] [5][6].
7. ADMINSTRATOR DOMAIN
Groovimovies.com is the administrative domain. It is the parent domain. That was
controlled by the domain controller.
Administration domain system was responsible for the overall control of the network
systems. That decides the action of the entire network system control. So this is the authority for
the client users in the network. They were controlled by the administration system.
That is called as admin-territory. That is responsible for the entire control system of the
network. That have the capability to control the entire system. In the network head assignment
was done by the realm controller. By this system the administrator or the controller of the
network can perform the operations like insert, modifications, etc. In the organizer zone that
gives the static permissions.
Client domains are just follow the instruction given by the administrator. In these system
some devices are employed to do this activity. So it carries the power to control the no of
systems under its control. That enables the standard structure in the network.

Configure of server access points,
For establish the network we need to do the below stated steps, and they are listed
below.
Provide IP for the devices in the network systems
Implement the NAT
Implement the firewall
Here the process of configuring the administrator was showed below.

8. Functional Needs
They are necessary needs of the system. That is responsible for the overall function of the
system. They have the higher amount of preferences because the actual performance of the
system was depends on this needs. For the network design some are the main parameters are
discussed below. And they are connecting wires, Computers, and Switches. Among these needs
the switch was considered as the main need. Because the entire system needs this think for the
successful operation of the system [7].
Switches
They are used in the network system to establish the connection among the computers. In
the typical LAN system consists hub for the same action. But that has some major drawbacks. So
we use the switches. They are the active element of the system. We can’t assume the network
system without the switch [8].
9. Non-functional requirements
Nonfunctional needs are also required needs of the network system. They doesn’t
participate actively on the system. But it enhances the actual quality of the system. So that are
called as quality needs [8] [9] [10]. Developed design of the LAN was showed below,
