## Chapter Overview

This course consists of nine chapters. Each chapter is organized into topics that compare the concepts and functionality of UNIX-based and Windows NT-based operating systems. Each chapter concludes with a summary, many of which contain a comparison table for a quick-fact reference in addition to a brief review of the pertinent points contained in the chapter.

#### Chapter 1: Microsoft Windows NT from a UNIX Perspective

This chapter compares the Windows NT and UNIX environment from an overview level. It points out the similarities in the underlying architectures of the two systems. This chapter also serves as the foundation for the course and provides a conceptual view of both environments, introduces the strategy by which course information is presented, and provides a definition of terms.

#### Chapter 2: Comparing Windows NT with UNIX Installations

This chapter assumes readers are familiar with the basic UNIX installation and emphasizes the process of how Windows NT-based operating systems are installed. It also covers obtaining and installing Service Packs and Hot Fixes for Windows NT, and discusses installation of additional software after Windows NT has been installed.

#### Chapter 3: Administering Users and Groups

This chapter explores the concept of user administration in both Microsoft® Windows NT® and UNIX, and compares user administration practices in Windows NT with UNIX. It also discusses Windows NT domains in relation to the UNIX Yellow Pages/Network Information Service (YP/NIS).

#### Chapter 4: Security in a Mixed Windows NT and UNIX Environment

This chapter examines the security models used by Windows NT and UNIX. It examines the logon process for both systems and highlights the differences between UNIX and Windows NT, as well as discusses the different processes for Windows NT logon. The chapter also emphasizes the differences in the default security configurations between Windows NT and UNIX.

#### Chapter 5: Working with Different File Systems

This chapter examines the file system structures of Windows NT and UNIX. It provides a comparison of the file allocation table (FAT) and Microsoft Windows NT file system (NTFS) supported by Windows NT. In addition, the topics of file system security and access for Windows and UNIX clients is covered. This area presents a strong diversion of process differences, although shares basic principals.

#### Chapter 6: Network and Internet Integration

This chapter presents an overview of the basic network operations, services, and functions in the two environments, and points out many of the similarities between network operations of the two systems. It begins with a discussion about TCP/IP, the common transport protocol shared by UNIX and Windows NT, and also addresses the issue of cross-platform management and X Windows.

#### Chapter 7: Service and Daemon Administration

This chapter compliments Chapter 6 by continuing to examine Windows NT services and the UNIX equivalents. It presents an overview of each service and daemon administration and compares the similarities and differences of each.

#### Chapter 8: Messaging in Windows NT and UNIX

There are a variety of different messaging programs and services for both Windows NT and UNIX. This chapter provides an overview of the variety of messaging programs and services available from both Windows NT and UNIX. It identifies those aspects of messaging that are comparable between Windows NT and UNIX messaging programs and services.

#### Chapter 9: Remote Access in a Mixed Environment

This chapter introduces the Windows NT Remote Access Service (RAS) and the add-on product Routing and Remote Access Service (RRAS) for Microsoft Windows NT Server. Similar to messaging comparison within Chapter 8, it discusses the variety of remote-access programs and services available in both Windows NT and in UNIX.
