ABSTRACT

This research is about Management of network operating system at Natural Forest Resources management and Agroforestry Centre (NAFRAC) in Shinyanga, Tanzania as the case study. It has been conducted for 16 weeks at effective from the 1st  October, 2007 to end of January, 2008.

A case study method was used because the study was at a single unit and it is less expensive compared to other methods such as survey.

The findings are presented in relation to the research questions, while analysis of data presented in relation to the proposed methods which are both qualitative and quantitative, with figures and tables by using scientific packages for social science (SPSS) & Microsoft excel (Version 2003). Data was interpreted in relation to the objectives of the study.

The researcher gave a conclusion in relation to research questions and data interpretation against objectives of the study, and finally the researcher provided some recommendations for any management or mismanagement of networks revealed at the NAFRAC for corrective measures.

The study finding shows that network operating system is not centralized at NAFRAC. Instead the NAFRAC uses workgroup connections so as to make networking at the NAFRAC. Peer to peer networking is not a centralized system in such; it is a system which enables sharing of printer and other resources but not from the server.

Following security problems the researcher recommends the management to discard the existing system and move to a new and more security conscious system which is client-server network

Client-Server networks provide centralized control over access to network resources. In addition access security can be customized to meet NAFRAC requirements, which helps to protect sensitive data from loss, destruction, theft, or unauthorized disclosure. Above all, most client-server environments have discretionary access control which allows a system administrator to grant or deny access to a file (resource).This will further increase system security. Most network operating systems (NOS) provide a number of fault tolerance features, such as disk mirroring, disk duplexing, and disk stripping. These features serve to improve reliability and minimize network down time.

ACKNOWLEDGEMENT

This work would have not been possible without support from a handful of people whom I owe

much thanks. I had to take much of their time for help on various issues that contributed to this work. It would be difficult to mention and thank every one individually for the support they have given me, but I will attempt just to mention a few to represent others.

First and foremost, I would like to thank my supervisor, Mr.Karisha.K.D for his guidance, advice and encouragement throughout the research process, from the time of writing the proposal, during the field work, up to the time this report was compiled and completed. Secondly, I owe to thanks my friends Shagina Isack, Meyasi Anzameni and Deogratius Mosha for their supports and advise about the study. Thirdly I would like to thank my friends, who kept encouraging me to struggle on despite my complaints about some difficulties. Their moral support had contributed greatly on successful completion of this work.

I would also like to express my appreciation for support and cooperation from management and staff of NAFRAC. For some of them I had to disrupt their time schedules in the process of my research study. Just to mention a few, I would like to acknowledge contributions from my case study supervisor Mr. Charles Ngatigwa, Mr. Andrew Chibwana, Pastory Mwesigwa, and Mr.Minja Emmanuel, George Mlenge and Rosalia shimba.

Finally, but not least, I would like to recognize contributions from management, staff and students of the university of Dar-es-salaam and Saint Augustine university of Tanzania (SAUT) for their support during my study. Pieces of advice and support I received from all of them made my learning time fruitful and have contributed greatly to successful completion of this work.To all those people who have contributed in one way or another, either morally or materially, I wish to thank you very much. May what you have given to me be repaid to you a million times.

CHAPTER ONE

1.0 INTRODUCTION

1.1 Background of NAFRAC

Natural Forest Resources Management and Agroforestry Centre (NAFRAC) was established on 1st April 2004. The centre evolved as result of spurring achievements and experience of both HASHI and HASHI/ICRAF project in involving local communities in the management of natural forest resources and Agroforestry practices. It is under the Forestry and Beekeeping Division in the Ministry of Natural Resources and Tourism (MNRT) and the office is located at Lubaga area within Shinyanga municipality. NAFRAC works with local communities in semi arid areas within Tanzania.

1.1.1 Vision

By the year 2010 NAFRAC sees 3,334,000 households with access to sustainable natural forest Resources and agro forest products and services for improved livelihood security and environment

1.1.2 Mission

The center’s mission is to scale up and out sound natural forest resources management and Agroforestry practices for the improvement of people livelihood through:

  • Participatory development of management strategies
  • Capacity strengthening and community empowerment,
  • Information packaging,disemminatin and networking,
  • Promotion of cultural heritage and eco-museum,
  • Participatory monitoring and evaluation.

The objectives of NAFRAC is to address the problem of over utilization of land resources triggers dwindling of forest resources, land degradation and eventually low productivity, also to extend to other semi arid area of the country the experiences and achievements attained by HASHI.

1.2 Background of the Problem

Many of the organizations in Tanzania are not yet implement the issue of managing network operating system in their network system, but some of them started to use network operating system in their business environments example banks. This system grew out because of the need of making use of scarce, sharing of software applications and peripherals costs such as printers, scanners and disk drives.

Some organizations tries to  make  commonly available of resources  such as operating system software applications across different number of computers connected to launched  network operating system server mean while many of the previous network provided only printing  and file access capability but not sharing resources  commonly such as software applications, printers and other devices

Presently, network operating system enabled software application to be launched on the single point computer (server) and then can be loaded across the network into local memory for individual use. An operating system processes raw system and user input and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system

1.3 Statement of the Problem

The Organization(NAFRAC) was using Windows XP as its network operating system which is graphical user interface (GUI), also all computers within Centre were networked under wireless local area network (LAN) which was peer to peer architechitured.Management of network operating system became a big problem because once it come the matter of security to protect viruses, update of windows and install software application was difficult, unless you protect viruses, update and install them individually as stand alone computer instead of done it at the server to all computer connected.

This study tried to find out the solutions about the problem above and how to manage network operating system. Thus, if the network operating system was managed well, it needs only a single installation of anti-virus at the server to protect all other computer connected from the server. Also single update and installation of software applications.

These reduce high running cost for software applications and management of operating system under the network, also it reduce the failure of the computer due to viruses attack from downloading files with viruses, share of affected diskette and running of affected programs that need to be scanned individually by each computer.

1.4 Objective of the Study

The following were the objectives of the study:

  • To determine the type of Network Operating System (NOS) the Natural Forest Resources Management and Agroforestry centre use.
  • To evaluate the advantages and limitations of existing network operating systems in the organization.
  • To explain how organizational management and information resource manages network operating system with computer network.
  • To explain which network technology fits into the Natural Forest Resources Management and Agroforestry centre and makes it better to serve its customer.
  • To determine the best type of operating system to be used in the organization.
