...Unit 1. Assignment 1. Windows 2008 Network Services Course Objectives and Learning Outcomes In this assignment, you will explain the function of DHCP and DNS. Assignment Requirements Write a 1-page report summarizing IT-management overhead in reference to DHCP and DNS. In your report, address IT-management overhead in reference to DNS and DHCP, with the following question in mind: 1. How many hosts does it take to justify the time and effort to setup a centrally managed solution for name resolution and address allocation? (In other words, is it worth setting up DHCP for two computers? 5? 25?) Consider both MS Windows Server DNS and DHCP as well as other, special use devices where DNS or DHCP may be built-in. 2. At what point should DNS or DHCP be considered a priority and require some level of redundancy? 3. Should servers use DHCP? Submission Requirements Maximum 1 page, Microsoft Word, double-spaced, 12 pt. font 1. How many hosts does it take to justify the time and effort to setup a centrally managed solution for name resolution and address allocation? (In other words, is it worth setting up DHCP for two computers? 5? 25?) Consider both MS Windows Server DNS and DHCP as well as other, special use devices where DNS or DHCP may be built-in. I believe one host is enough. In fact, if the host has a functioning network interface which is connected to a network chances are it is managed by DHCP uses DNS for name resolution. Although...

...Services Unit 1 Assignment 1: Installing Server Roles with a Batch File Assignment: After careful consideration, it was decided by the corporate IT team that in order to increase security and lower your attack surface, Windows 2008 Server Core would be installed on a group of your servers. However, a few roles need to be installed on the server and your Senior Administrator is not familiar with installing roles on a Server Core machine. Using Internet research and use notepad to create a batch file to install the following roles: DHCP, DNS, Print Services and Hyper-V. Students will complete a notepad file that will successfully install all of the roles mentioned. Save the file using the name Roles.bat. 1. DHCP: start /w ocsetup dhcpservercore. 2. DNS: start /w ocsetup DNS-Server-Core-Role 3. PRINT: start /ocsetup Printing_ServerCore-Role. 4. SERVICES: start /w ocsetup MediaServer, 5. HYPER- Start /ocsetup Microsoft-Hyper-V. Questions 1. What does the /w switch do? Why is it used? Specifies the warning level, an integer in the range 0 through 4. There is no space between the /W switch and the digit indicating the warning-level value. 2. What switch is used to remove a role? To remove a role you would need to commas to separate command names. 3. What is the command to start the DHCP Server service? To open DHCP, click Start, click Settings, click Control Panel, double-click Administrative Tools, and then double-click DHCP. 4. What...

...EN1330 Client-Server Networking 2 Unit 1. Assignment 1 9/25/2014 A Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resources connected to the internet or a private network. It associates various information with domain names assigned to each of the participating entitles. It translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. The best way that I have been able to explain it, it works like a phone book for the internet by translating hostnames into IP addresses. But unlike a phone book, the DNS can easily be updated and quickly. The internet maintains two principal namespaces, the domain name hierarchy and the Internet Protocol address spaces. A DNS name server is a server that stores the DNS records for a domain name, such as (A or AAA) records, name server records, and mail exchanger records. A DNS name server responds with answers to queries against its database. The Dynamic Host Configuration Protocol is a Standardized networking protocol used in Internet Protocol networks for dynamically distributing network configuration parameters, such as IP addresses for interface and services. With DHCP computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually. DHCP is used by computers for requesting Internet...

Here is your options on what you can do with DHCP: Table 4.5 Default DHCP Options Code Option name Meaning 1 Subnet mask Specifies the subnet mask of the client subnet. This option is defined in the DHCP Manager Create Scope or Scope Properties dialog box. It cannot be set directly in the DHCP Options dialog box. 3 Router Specifies a list of IP addresses for routers on the client's subnet. Multihomed computers can have only one list per computer, not one per network adapter. 6 DNS servers Specifies a list of IP addresses for DNS name servers available to the client. 15 Domain name Specifies the DNS domain name that the client should use for DNS computer name resolution. 44 WINS/NBNS servers Specifies a list of IP addresses for NetBIOS name servers (NBNS). 46 WINS/NBT node type Allows configurable NetBIOS over TCP/IP (NetBT) clients to be configured as described in RFC 1001/1002, where 1 = b-node, 2 = p-node, 4 = m-node, and 8 = h-node. On multihomed computers, the node type is assigned to the entire computer, not to individual network adapters. 47 NetBIOS scope ID 1 Specifies a text string that is the NetBIOS over TCP/IP scope ID for the client, as specified in RFC 1001/1002. 51 Lease time ...

...Unit 1 discussion 1: familiar protocols Q 1) What role does TCP/IP play for internet communications? TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP. Q 2) What role does IP play in data transfer over the internet? IP is a protocol. Simply said, a protocol is a set of rules governing how things work in a certain technology, so that there is some kind of standardization. When put into a network communication context, a protocol is the set of rules governing how packets are transmitted over a network. When you have a protocol, you are sure that all machines one a network (or in the world, when it comes to the Internet), however different they might be, speak the 'same language' and can integrate into the whole framework. IP is probably the most common protocol over the Internet. It is the set of rules governing how packets are transmitted over the Internet. The IP protocol standardizes the way machines over the Internet or any IP network forward or route their packets based on their IP addresses. Q 3) How does Dynamic host configuration protocol ease management of IP addresses...

...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...

...Evening Unit 2. Assignment 1. DHCP Troubleshooting Dear Junior Administrator, I would start by rechecking your initial configurations to make sure the setting were saved. Once that is done, check to see if the workstations have picked up a new lease or not. If that doesn’t resolve the issue, did you check to make sure the server is up and operational? Have any Error messages or pop up’s appear with any type of warning, if so what did it say? Once the server has been checked, if it is working properly we will check these three common problems; 1. “The client might be configured to use an IP address not provided by the server. 2. The server sends a negative response back to the client, and the client displays an error message or popup indicating that a DHCP server could not be found. 3. The server leases the client an address but the client appears to have other network configuration–based problems, such as the inability to register or resolve DNS or NetBIOS names, or to perceive computers beyond its same subnet.”(Troubleshooting DHCP) On the chance that the DHCP server is off I would like you to follow these steps to try to restart the DHCP server. 1. “Start Windows Server, and log on under an account with Administrator rights. 2. At the command prompt, type net start dhcpserver , and then press ENTER. As a helpful tool Use Event Viewer in Administrative Tools to find the possible source of problems with DHCP services.”(Troubleshooting DHCP) I...

...Unit 1 Individual Project: TCP/IP Instructor: Michael Pry Robert Long American Intercontinental University Abstract In this brief I will attempt to explain the usage of the TCP/IP protocol so that the user may better understand the functions of this protocol. I will also provide the pertainate information for the configuration of the TCP/IP protocol to you system this will include the setting for this configuration. One of the most popular network protocols in use today is TCP/IP, (Transmission Control Protocol / Internet Protocol) which is the basic transmission language or protocol of the internet. This may also be utilized as a communications protocol in a private network as well, such as intranet or extranet. If you utilize a set up with direct access to the internet your computer is given a copy of the TCP / IP program as well as every other computer that you deal with (messages for example) or for information they to have a copy of TCP / IP. So let us address TCP/IP for a minute, TCP/IP is a two layer program, the higher of the two layers is the Transmission Control Protocol which manages the assembling of the message or file into a smaller packet. These are transmitted over the internet and received by a TCP layer which reconstructs the packet into the original message. The lower layer IP (Internet Protocol) deals with the address part of each packet so that it is routed to the proper destination. Every gateway computer on this network will check the...
