Assignment 1: IT Consultation for Fast Paced Financial

Assignment 1: IT Consultation for Fast Paced Financial Fast Paced Financial is a start-up company that has decided to deploy Windows Server 2008 network as their base. There are many advantages to running Windows Server 2008 such as Active Directory Domain Services, integrated DNS services, and easier authentication. Windows also offers ample support for their products to assist companies in better utilizing all of the advanced features. The owner of Fast Paced Financial has many reservations as to why he wants Windows Server 2008 utilized within his company, but he also does not understand why it is necessary to have such an ample amount of money dedicated to his IT department. A substantial amount of money is required to deploy a Windows Server 2008 network due to licensing and hardware costs. This is a concern to the Owner Mark Cohen since he does not work with IT for a living he does not understand all of the requirements that a company requires to run its network. Little to no downtime and preventing the loss of sensitive data are his primary concerns when it comes to his network functionality. “Some of the benefits of Active Directory DS include a hierarchical organizational structure, a single point of access to network resources, and the ability to create trust relationships with external networks running previous versions of Active Directory and even UNIX.” (Course, 2008) These are such great benefit since it is important that the data saved on the network is easily accessible and well organized. If the company organizes all of its data in a hierarchical structure by department then it will be easily retrieved by employees. Employees will know to look in a certain parent folder to find data on a topic rather than looking through randomly placed files and folders on a large shared drive. Fast Paced Financial has fpf.com designated as its DNS name. They have a main office located in New York City and they also have remote offices located in Houston, Indianapolis, and Los Angeles. They would like to have separate child domains in their main forest for each location. This will be easily demonstrated through trees. The remote sites will have their own DNS records as follows: ny.fpf.com, la.fpf.com, and hst.fpf.com
FPF.com
ny.fpf.com la.fpf.com hst.fpf.com As Fast Paced Financial’s network has evolved and is now prone to server outages, which is a big concern for the company’s owner. A server holding the PDC FSMO role has gone offline affecting all the users and requiring the IT department’s immediate attention. The FSMO has five roles that are unique to different servers. One role is the Relative Identifier Master; it assigns relative identifiers to domain controllers within a domain. A second role is Infrastructure Master which is responsible for reference updates from domain objects and sends them to other domains. A third role is Primary Domain Controller Emulator which provides backward compatibility with Microsoft Windows NT 4.0 domains and other down-level clients such as UNIX. This also manages password changes, account lockouts, and time synchronization for the entire domain. The fourth role is Domain Naming Master which has the authority to manage the creation and deletion of domains, domain trees, and application data partitions within the forest. The fifth role is the Schema Master, which is responsible for managing changes to the Active Directory Schema. When the PDC FSMO is down it directly affects all the users. It locks out accounts, does not allow for password changes, and foreign domain children do not have time synchronization with the rest of the network. To restore the outage to the network you should have a back-up server with PDC FSMO so that you have redundancy rather than a single failure point. If there was an outage to the Relative Identifier Master then it could cause a problem with authentication of an object’s security identifier within the network. To solve a problem with this outage you can assign another domain controller within the domain to be the back-up RID Master in case of an outage so that the outage would seem seamless to the users on the network. If there was an outage in the Domain Naming master role it would also be a problem for users. If this domain controller goes down it would mean that no one would be able to create or delete any child domains, domain trees, or application data partitions. You can only have one of these controllers per domain, but you can designate a back-up domain controller to initiate in case of a server outage.
Fast Paced Financial’s network is always evolving and new issues seem to arise regularly. The Websites that have been configured are not fully routed, causing more problems. “The SMTP transport (SMTP over IP) provides asynchronous replication. In asynchronous replication, the destination domain controller does not wait for the reply and it can have multiple asynchronous requests outstanding at any particular time. Thus in asynchronous transmission, the reply is not necessarily received within a short time. Asynchronous transport is appropriate for linking sites in networks that are not fully routed and have particularly slow WAN links.” (Microsoft, 2012) This type of asynchronous replication will help to increase replication efficiency utilizing the existing hardware so that additional equipment will not need to be purchased.
One of Fast Paced Financial’s remote sites has an unreliable WAN link so the new server administrator would like to add another global catalog server to the network to assist during down times. This would be very helpful since the employees at the remote site have not been able to accomplish their daily tasks due to WAN downtime. One additional server should not affect the functionality of the network and the benefits to the remote site would be unparalleled. One possible implication of placing a global catalog at a remote site would be bandwidth. “Configuring an excessive number of GCs in a domain wastes network bandwidth during replication. One GC server per domain in each physical location is sufficient. Windows NT sets servers as GCs as necessary, so you don’t need to configure additional GCs unless you notice slow query response times.” (Petri, 2009) Although bandwidth is an issue with all companies who are networked, this one additional GDC should not cause any issues.
Fast Paced Financial has a very intricate network that is across the globe. They have run into networking issues, authentication issues, and server outages. The network has evolved over time, will continue to grow and develop with new technology with the additions of offices around the globe. The company is fully functioning and routed with Windows Server 2008 running their backbone. It should be able to handle a substantial amount of growth further avoiding show stopping malfunctions.

...Wal-Mart Item Finder Application Kelsey Polston English 315 Professor Mark Crilly November 10, 2012 Table of Contents Transmittal……………………………3 Executive Summary…………………..4 The Problem…………………………..5 Wal-Mart History……………..5 Customer Technology………...5 Conclusion……………………………5 References……………………………7 Transmittal Everyone in the United States shops at Wal-Mart Corporation at some point in their life because they have so many items that are useful in everyday life. It can be very frustrating when looking through their many items and you know they carry a product that you simply cannot find. With the popularity of smart phones on the rise, almost 1 per household in the United States, an advanced Wal-Mart application would make sense. Since Wal-Mart already makes their inventory count available for customers through their website, why not add a feature that allows you to also locate the aisle number of the item you are looking for. Since Wal-Mart already has a smartphone application they have invested the time and interest into learning how to make and maintain this specialized program. It would not be too much to simply add a feature to an already existing application. Executive Summary The cost effectiveness, the added customer satisfaction, and the increase of sales for previously “dud” products are enough reasons to add one more feature to the Wal-Mart application. Customers leave the stores every day and go to other large retailers to purchase products that...

...online customer services: ◗ Customer preferences. Customers tend not to do much self-service in terms of getting information from companies (e.g., only 19% use FAQs), so they require attention. As more companies offer online self-service, though, this situation is changing. When contacting companies for information, customers use e-mail more than the telephone (71% versus 51%). ◗ Types of service. Four types of service exist, based on where the customer is in the purchase experience: during shopping (search products, compare, find product attributes); during buying (questions on warranties, billing, receipt, payment); after placing the order (checking status in processing and in shipping); and after receiving the item (checking return procedures, how to use the item). ◗ Problem resolution. Customers expect quick resolutions to problems, and expect problems to be resolved to their satisfaction. Therefore, easy returns and order tracking are desirable. ◗ Shipping options. Several shipping options are usually needed to make customers happy. ◗ Fraud protection. Customers need to make sure that sellers or others are not going to cheat them (Chapters 9 and 14). ◗ Order status and updates. Customers want to have some way to check on the status of their order, which involves tracking either by phone or online. These services are highly desired, including order notification and a clear return policy. ◗ Developing customer relationships. This includes building trust, providing security...

Operation Strategy Quality Measures

...The Role and Measurement of Quality in Competition Analysis 2013 The OECD Competition Committee discussed the role and measurement of quality in competition analysis in June 2013. This document contains an executive summary of that debate and the documents from the meeting: an analytical note by the OECD staff and written submissions: Australia, Canada, Chile, the European Union, Indonesia, Japan, Mexico, Portugal, United Kingdom, Ukraine, United States and BIAC. A note by Theodore Voorhees Jr. as well as a detailed summary of the discussion are also included. Competition policy is just as concerned with quality as it is with prices. While the importance of quality is undisputed and issues about quality are mentioned pervasively in competition agency guidelines and court decisions, there is no widely-agreed framework for analysing it which often renders its treatment superficial. There are a number of reasons why in practice, courts and competition authorities rarely analyse quality effects as rigorously as they analyse price effects. First, quality is a subjective concept and therefore much harder to define and measure than prices. In addition, microeconomic theory offers little help in predicting how changes in the level of competition in a market will affect quality and it is usually up to empirical analysis to determine how quality will change in response to varying degrees of competition in the context of particular markets. Given difficulties in terms of the evaluation...
