Today’s enterprise networks are more and more likely to be Windows based or at the very least have large Windows components coexisting with other network operating systems (NOS) such as the many UNIX/Linux variants, or Novell’s NetWare. Since the time that Microsoft began offering Windows NT Server version 3.51 through today’s Windows 2003 Server and its upcoming successor, codenamed “Longhorn”, the job of centralized network authentication and administration has been built around Microsoft’s domain network architecture.
Over the years Microsoft’s domain architecture has changed and evolved significantly. The introduction of Active Directory has eclipsed the older Primary Domain Controller (PDC) and Backup Domain Controller (BDC) model used prior to the introduction of Windows 2000 Server. The role of the domain in Microsoft’s current network schema can be defined as “a logical group of computers characterized by centralized authentication and administration” (DiNicolo, 2004, p. 10). Today’s modern Microsoft domain architecture often utilizes the concept of multiple domains. Examples of the usage of multiple domains can be found in the design of Windows 2000 and 20003 network infrastructure. It is often necessary and more efficient to create multiple domains to reflect different departments within an organization or to reflect different geographic locations within a company. The addition of multiple domains can assist with the improving of replication performance between domain controller Active Directory databases as well as assisting in the administration of differing security policies. When multiple domains are used, Microsoft terminology describes the actual network architecture schema in terms of Forests and Trees (DiNicolo...

Active directory is the backbone of Windows Server 2012 and fundamental technology in almost every business / enterprise. ADDS is the server services for security and permission in Windows environment. As we’re planning to set up three sites, create user accounts and security policies for those computers, we will need to use Active Directory. Active Directory configuration will present the most optimized replication of traffic and data between each of the three sites and provide fundamental of failover and redundancy.
The most recent history of our HMI software upgrades has been full of small upgrades, hot fixes (quick patches provided by GE) and changes to minor configuration items on the projects themselves. Recently, spurred by an announcement from Microsoft that Windows NT would soon be unsupported, GM decided it was time to upgrade its servers. The new servers would have Windows 2003 Server and any client or production computer would have Windows 2000. Any SQL Server will run SQL 2000 after the upgrade. The project began as a somewhat simple server hardware and software upgrade and has moved into a full-blown consolidation, network upgrade and server consolidation. From the outset, both EDS and GM have agreed to use a CMMi framework for all actions relating to this upgrade.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
This essay will discuss Enterprise Resources Planning (ERP) implementation, specifically in the factors which can leads that ERP implementation to successful and unsuccessful ERP implementation.

Microsoft was able in the OS segment to double their revenue per PC when Windows 3.x emerged which still needed MS-DOS to run. Most of the sales Microsoft made were to OEMs who would take the additional step of installing Windows on a computer’s hard drive. This strategy was effective in that the cost of production was relatively low, as an OEM may only need a single master copy to do the installation. The costs to Microsoft would largely be bore in R&D expense rather than production. As part of the Microsoft business model for this segment, Microsoft designed their OS to need periodic upgrades. The upgrades did come at a cost, and in essence, Microsoft was able to create an “annuity” stream for the Microsoft OS segment. In this segment, Microsoft had a monopolistic structure that allowed them to realize huge returns, especially during such a period of technological growth and rapid obsol...
It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security goals. Using the Defense in Depth strategy will require an understanding of the interactions between devices occuring within the network.
Enterprise Resource Planning (ERP) -. Abstract ERP systems are meant to help companies and businesses operate more efficiently when they are not. The main goal for a company is to choose a vendor that will give them the safest and easiest way to operate efficiently and achieve their business goals. What is an ERP?
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
Network Solutions, Inc. is a worldwide leader in hardware, software, and services essential to computer networking (Aguinis, 2013, p.31). In the past, this company has used over 50 different systems to measure performance management. Even with the large amounts of different systems to measure performance, only a fraction of employees were receiving performance reviews, and less than 5% of employees received the lowest category of ratings. Also, the organization had no recognition program for employees with a higher category of ratings. In addition to the lack of employees not receiving reviews, it was noticed in the organization that performance problems were not being addressed or resolved.
