...NT1330 Unit 2 Assignment. Due before class Week 3. A. Students will respond to the following technical support email from a junior IT admin with further questions and considerations. Facilitation Read the scenario below and respond in detail with clarifying questions, suggested approaches and/or possible solutions. Dear IT Admin: I am working at a branch office and have been tasked with changing out the DHCP scope to match the overall corporate IP address scheme. The main office assigned me an IP address range of 192.168.0.200 through 192.168.0.225. I changed the scope on Friday afternoon and came in on Monday morning to discover that only some of the workstations had picked up new leases from the new DHCP scope. Any ideas as to what may be happening, what I might check or adjust? Thank you, Junior Admin B. Students will respond to the following technical support email from a junior IT admin with further questions and considerations. Facilitation Read the scenario below and respond in detail with clarifying questions, recommendations and/or considerations. Dear IT Admin: I am working at two branch offices and have been tasked with where to place Active-Directory Integrated DNS Servers and what type to use. One of the branch offices is very small (maybe 5 users) and has very slow network connectivity. Do I need a DNS Server and, if so, which type of zone should it host? The second branch office is much larger (about 30 users) and has better...

...Dear Junior Admin, PCs generally have an eight day default lease period. The PC will not make contact to the DCHP server again until halfway through the lease time. Since you changed the scope on Friday, the PCs that just renewed a lease will not contact the DCHP until Tuesday. You may force the PCs to grab new IP addresses by opening a DOS prompt, and do an “ipconfig/release” and an “ipconfig/renew” on each computer. If the problem still isn’t solved, check your scope configuration, and make sure the network/subnet mask match what is configured on the router that is connected to this local LAN. Terra Klaase IT Admin PART B Dear Junior Admin, Active Directory integrated zones must be hosted by Domain Controllers (DCs), and all Active Directory integrated zones are primary zones. Given this, we’re really talking about where to place Domain Controllers servicing the additional role of DNS server. Determining where to place DCs/DNS servers isn’t always straight-forward. However, as a rule of thumb, I take the view that any branch location that’s going to be utilize Active Directory services (authentication, file services, etc.), benefits from having a local DC and domain-integrated DNS services. You might already know much of this, so bear with me… When deciding where to place DC/DNS Servers, keep the following things in mind: * Domain members rely heavily on DNS services to locate domain resources. For example, when a domain-joined computer boots, it queries domain Service Locator...

...Task 2: Addressing a) Network components require addresses to speak with each other. The components require the addresses since it extraordinarily distinguishes every component and furthermore organizes them so that every component can be located globally order to course messages for conveyance to it. Without correspondence, the components wouldn't know where to convey specific data and information. Each component has two sorts of addresses. One is the physical address and the other being the logical address. The physical address is a MAC address (MAC meaning media access control) and the logical address is an IP address (IP being Internet Protocol). An IP address is an address that is bound to a network device like a PC through software. In a Windows-fueled PC, the operating system will enable a client to arrange the IP address a specific workstation will have. This IP address is utilized to give authorization to all network-aware programs, for instance, a web program or a massively multiplayer online game, to utilize this address when speaking with different hosts....

...NT1330 Client Server Networking II Mr. Pham Unit 2 Assignment 1 Dear Junior Admin, Regarding your task with changing out the DHCP You can start by checking the workstations and seeing if they have an static IP setup on the network adapter. There are 2 ways to check this. The first way is to click on the run command in the start menu and type cmd and hit enter. Next type in ipconfig /all, depending on how many Network Interface Card or NIC cards are installed (both logically and virtually.) you might get a long list . Look for your main NIC card that you are configuring. Once you find your NIC card that you are looking for, you should see a line that says DHCP Enabled. If there is no static IP address set up then it should say yes. The second way to check is to open the control panel. Find and open the Network and Sharing Center. On the right hand side you should see an option for change adapter settings. Select you main NIC card and right click and select properties. Select and double click on Internet Protocol Version 4 (IPv4). Once the window pops up, make sure that both the radio buttons for obtain IP Address automatically are selected. You should also check to see if each workstation has renewed its DHCP lease. To do this you can repeat the steps in the first way to change the DHCP setup. Once again you want to look for your main NIC card that you are configuring. Once you find your NIC card that you are configuring you should see 2 lines that say Lease Obtained...

...1.1 To conquer this weakness, several methods could be used. Firstly, more staff need to be trained in completing the bank reconciliations so that more than one person is capable of completing it should the Accounts Manager have different priorities. An alternative option is that the company employ another trained member of staff which would be advantageous to bring more experience to the business and makes the process of completing the bank reconciliation easier as there would be two people that the job could be completed by. This would then hinder unprofessional actions being taken such as leaving the information accessible to anyone, or altering the cash book furthermore, preventing more serious issues in the future as any staff completing the bank reconciliation will be adequately trained on how to complete it accurately. Moreover, they would be taught about confidentiality, thus helping to keep the records safe and secure and preventing issues such as fraud. Although hiring a new member of staff whom was already trained would be quicker than training existing employees; it would also prove more expensive to the company as they would then be paying wages to an extra, unnecessary employee therefore, although training could take an extensive amount of time, it would be more appropriate financially in the long-term to train existing employees who would also already be familiar with the business and how they work. 1.2 Eliminating this weakness could be achieved by introducing...

...NT1330-Unit 2 Exercise 1 DNS Scenario Dear junior IT, Thank you for contacting me regarding your questions, and trust that I will do my best to help you. From what I understand, you work at two branch offices, and have been given the responsibility of discovering where to place an Active-Directory Integrated DNS server. You also have some question of what type DNS server would best meet your company’s needs. First let’s begin with the smaller branch supporting perhaps five user/workstations, with an unusually slow network. The question with such a small branch isn’t really about what kind of DNS server you need, but do you need a DNS server at all. If there is a very high level of file/data sharing, then yes perhaps you could benefit from a server, but configured in a secondary zone, such as an ADI. However, if there is not enough file/data sharing to really warrant the presence of the server, an ADI server could potentially slow down an already sluggish system. Now let’s move on to the second, much larger branch supporting around thirty users. You stated that this branch has a much better network connectivity than its smaller counterpart. In this case, I would recommend a DNS server set up in the primary zone. The primary zone is the primary source of information within this zone. I would also further suggest moving your servers from the smaller branch to your larger branch. All files from the smaller branch could be accessed via a “VPN” remote link. This would allow...

...Unit 2 Exercise 1 DNS Scenario Hello, I have received your email, and will do my best to help you out with the tasks put before you. First, let me say that a good rule of thumb to go by for DNS as far as users, and computers is if you have 10 or more. Seeing that you have 5 it is not a must have, but if your company has the money allocated for this project than go ahead. They might have growth in mind for the near future. If that is the case then the zone you would want the 5 employees in would be secondary if not possibly try setting up a VPN virtual private network to a server at the larger office. As far as the branch office with about 30 users I would definitely use a DNS server. You would put this branch in the primary zone. Another zone or setting that could be used is Active Directory Integrate Zone. The Active Directory Integrated zone stores its data in Active Directory and it does not need DNS zone files. It is in fact an authoritative primary zone and the data gets replicated to other domain controllers as part of Active Directory’s replication process, and a benefit of this type of zone is that it uses the security features of Active Directory. Active Directory will automatically replicate DNS information to other DNS servers that are installed on Active Directory Domain Controllers. I do hope that the information I provided was helpful, and if you have any further questions please feel free to contact me...

... I took notes on the reading assignments, then I worked on the programming assignment. The programming assignment was very simple, just a couple of variables, some math, and the comments. I didn’t have any trouble writing it, but I did take a little time looking for ways that I could improve the program and making sure that I met all of the criteria. I was somewhat surprised how straightforward it was because I was anticipating the course to be difficult from the beginning. The difficulty of the assignments will increase quickly, I expect. So for now I am hesitant to go too far ahead on my own since I haven’t taken a programming course before and I don’t want to get on the wrong track. I realize that there is a long way to go, but I’m still excited to start working with Python. There was no specific feedback this week, and the feedback for from last week’s discussion board was somewhat general and not about my work itself, so I don’t have much to comment on yet. I did get the impression that the other students understood what they were doing. The discussions might become easier as we go along. I studied more of the history of personal computers this week. The timeline and major developments, and some of the background of the people and companies developing the machines. I was surprised by just how disorganized the development was, and how much small ventures contributed to large developments in technology. I was under the impression that development was being largely driven by...

...Unit 2 Assignment 1 DHCP troubleshooting Hello Junior Administrator, Let me clarify your parameters and intent… You have stated that you were tasked with changing the DHCP scope to match you IP addressing scheme. The IP address range you are using is 192.168.0.200 through 192.168.0.225. I have come up with a couple solutions and approaches to help you with your problem. First of all make sure you have typed all your numbers correctly. At times, a simple number incorrectly typed can throw the entire scheme off. Perform the same check for your subnet inputs as any slight number mistype will negate everything that you are trying to achieve. Make sure the scope is under the established DHCP local role IP address range on your assigned server. My next approach would be to see if there is connectivity between your user machines and the network. Make sure your network interface cards are all up to date and functioning. The other approach I will suggest can be involved if you’re not used to working with your command prompt however it’s doable with a detailed memo to your employees. I would have them release their IP addresses and renew them to through the console command input. I understand that most users may not have the required know how to do these tasks but for those I would actually go and input the commands manually and hopefully this will finally fix your problems. If you still encounter issues, please feel free to contact me and we can walk through...

Should you find yourself needing more control over the software and applications you use. It might happen you are on a Windows shared plan but need Linux applications and services. You have the options of migrating everything to a Linux server or upgrading to a VPS, where you can control what operating system you use as well as the applications. These are just some of the possible reasons why one would move to a VPS. There are other reasons such as you not wanting to share your resources. Furthermore, you can even look at your future plan. If you are looking to grow your business fast, using the scalable VPS option could be the best option for you. Features of VPS The VPS is a great tool for those looking to upgrade from shared hosting but do not want to fork out the cost of getting a dedicated server. The virtual server has all the features of shared hosting with the added benefit of having some of the features of a dedicated server. But what are these features that make using aVPS better than using shared hosting? • Guaranteed Resources: You will have guaranteed resources. This is because the virtual server is compartmentalized from other users on the host server as such all the resources that you have access to are all yours to use and you will not share these with other clients. • Root Access: As the virtual server is basically...
