DHCP:

DHCP is a standard protocol that make TCP/IP network configuration much easier for the administrator by dynamically assigning IP addressing and providing additional configuration information to DHCP clients automatically.
DHCP configuration information can centrally manage all information can stored in one single location. Because DHCP is dynamically host configuration can eliminate the prose of manually configured all client IP address. Other benefit of DHCP is the opportunity of set up the subnet mask, default gateway and the DNS IP address. And give the flexibility of change IP address when is need it.
The DHCP server have different ways to communicate with the client: * DHCPDISCOVER: is when the client send a broadcast to find a DHCP server. * DHCPOFFER: soon and he server find the client than the server respond, and send a offer. * DHCPREQUEST: is when the client respond to the offered from the DHCP server. * DHCPDECLIEN: mean that the client declined the DHCP server offered. * DHCPACK: is the way the DHCP server confirm the IP address and configuration parameters. * DHCPRELEASE: is the way the client cancel the IP address lease. * DHCPINFORM: is a message send by the client asking for additional configuration parameters, also use for detect unauthorized DHCP servers.
Using those terminology the process of communication is in this form: 1. The client send a (DHCPDICOVER) broadcast to find the DHCP server. 2. When the client found the server the server end an offer (DHCPOFFER). The message go with the server source, MAC address of the requesting client, and a server identifier. 3. After the client receive an offer for at list…...

Unit 2 Assignment 1 Dhcp Troubleshooting

...Dear Junior Admin My first question would be what have you done to this point about the issue? What OS are the computers running that have not picked up the new DHCP scope? Start by checking the DHCP setting and configurations are they all correctly configured? Try renewing the IP addresses on the workstations that have not picked up the scope it maybe do to the IP lease agreement. The Lease period defined for your DHCP, I think 8 days for wire and 24 for wireless. So machines will not request a new IP address until this lease expires. If a Machine reboots (or any similar events like disabling then enabling the NIC), it will ask for a new IP address from the DHCP, so I think the few machines that received new IP addresses from the new scope were rebooted. You should also check the system event log and DHCP server audit log files for details on any problems. Make sure the address scope has enough addresses if not widen the scope range. Check to see if it is a router/firewall problem and makes sure you have the service enable. If the OS is Windows XP, there is a known issue in which Winsock corruption has caused this exact issue. If it is a Winsock corruption on an XP machine you One thing that you can try is Start Run type in 'cmd' (without the quotes) in the command prompt type: netsh winsock reset library With prompts, it should look like C:\Windows > netsh netsh> winsock netsh winsock> reset library I think you need to restart also. Thank you, IT Admin...

...Javier Dominguez DNS & DHCP DNS allows people to use meaningful names, such as http://www.yahoo.com.proxy.itt-tech.edu, to find Internet-based resources. In this way, DNS has allowed users from a wide range of educational backgrounds to makes use of the Internet. DNS eliminated the need to manually remember IP addresses and replaced that system with human-readable names instead; DNS was invented to solve the logistical problems that arose because too many hosts were on the Internet to be able to keep track of using a manual list of addresses. In other words DNS function is to translate names to IP addresses and vice versa, that way instead of remembering a long IP address you can just type a name that is easy to remember. http://library.books24x7.com.proxy.itt-tech.edu/assetviewer.aspx?bookid=12254&chunkid=309282908&rowid=24 With the increasing number and different types of devices attaching to the network, managing IP addresses efficiently and accurately introduces many challenges for network operators of large-scale networks, including service providers and enterprises. Both Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) are mission-critical capabilities that need to be able to scale, and many service providers have created dynamic service delivery based on DNS to achieve service quality and deliver advantages. However, if DNS fails, then the Internet fails. Assigning a unique address to every device connecting to the network has...

...Assignment 1 DNS and DHCP can make a system administrator's life simpler and easier. Fortunately, the protocols are so flexible that they can be implemented either together or separately depending on the size and configuration of your enterprise network. So whether you have 5 or 5000 computers in your network this would be justifiable action because of the following reasons: Looking up IP addresses can be a nightmare if you have more than a couple to remember If you have network-enabled printers, unless you lock the address, it will change every time you disconnect the printer from the network. This can be extremely frustrating for the users. If you have more than a small number of machines, then you should be looking at implementing DNS in addition to DCHP. There are a number of ways to implement DNS in-house depending on the specifics of the company computer systems architecture. The choice depends on the available skills in your shop and the network configuration. One nice thing about implementing DNS is that once it is set up, it pretty much runs without much need for human intervention. That means that if you hire a consultant to do the initial configuration, you only need to maintain the service with a minimum of skills and resources. I found two choices for configuring the service using Microsoft Active Directory or (the newest possibility) purchasing a DNS/DHCP service appliance. Whatever implementation you choose, once it is configured, the best DNS/DHCP server......

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 Assignment 1 Dns

...The use of DHCP is highly recommended and there are a number of obvious reasons why you should use it. As mentioned before, there are two ways you can configure client addresses on a computer network, either manually or automatically. Manual configuration requires the careful input of a unique IP address, subnet mask, default router address and a Domain Name Server address. In an ideal world, manually assigning client addresses should be relatively straight forward and error free. Unfortunately, we do not live in an ideal world; computers are frequently moved and new systems get added to a network. Also if a major network resource, such as a router (which interconnects networks) changes network addresses, this could mean changing EVERY system's configuration. For a network administrator this process can be time consuming, tedious and error prone. Problems can occur when manually setting up your client machines, so if you have the option to set-up your client machines automatically, please do, as it will save you time and a lot of headaches. DHCP has several major advantages over manual configurations. Each computer gets its configuration from a "pool" of available numbers automatically for a specific time period (called a leasing period), meaning no wasted numbers. When a computer has finished with the address, it is released for another computer to use. Configuration information can be administered from a single point. Major network resource changes (e.g. a router changing......

Nt1330 Unit 2. Exercise 1. Dns Scenario

...Aaron Battaglia NT1330 UNIT 2. EXERCISE 1. DNS SCENARIO It is not required to put a DNS server in such a small location for only five users and snail like network connectivity doesn’t justify the amount of money it would cost to install a server(s) in that area. One exception would be if there is a great amount of file sharing, or other information that would need to be accessed daily by other spots on the network. This sometimes but rarely happens but we could have a situation where we put it in the in the server but we set it up as a secondary or Active Directory Integrated zone type. I recommend installing the servers in the location where you have 30 users and fast internet connection. You could do this also, try storing all the files from either location in the bigger office, and in the smaller location you could remote connect through Virtual Private Network. When we do this all the information from the smaller sight is stored off site. The sight with five users can be run with a cheap router and the server that has thirty users at the office will be set up as the primary zone; since this is utilizing the fast internet connection and has more users this is our MAIN BASE which you can call home. =) If you were to run Domain Name System on domain controllers there are Active Directory Integrated zones and Active Directory Integrated zones. In classical Domain Name Systems the zone data is stored in text files which sit on the Hard Drive; which of course is......

Dns vs Dhcp

...DNS and DHCP, how they make your life easier DNS stands for domain name system, and DHCP stands for dynamic host configuration protocol. Most of the time they are used in conjunction with connecting to a network, though they are not reliant on each other, nor do you have to use either one to connect to your network. They just make the job of setting a network up that much easier, but you can still do everything manually if you choose to do so, it just won’t be anywhere near efficient. DHCP allows assigning IP addresses to computers on a network automatically instead of having to logon to each individual computer and set the addresses yourself, as well as keeping track of the addresses you have already assigned. DHCP takes place on your router, you connect your computer to the router, either wired or wireless, and the router automatically assigns an available IP address to the device and it keeps track of this so no two devices that connect to the router are given the same IP. If two devices with the same IP try communicate with the router, the device that connected first will work; the second device will act as if it has no connection. If the first device is shut down, the second device will then start to work, the network connection may need to be reset first though on the second piece of equipment. Two devices just can’t share the same IP address at the same exact time. A DNS server takes the domain name of a website and translates it into an IP address which a......

Nt1330 Unit 2 Homework

...Phil Bohrer, NT1330 Unit 2 homework. 4/02/12 Assignment 1: DHCP Troubleshooting. Check the workstations using ipconfig /all and find out if the ip range is within the address range you assigned, if it is a different address then the workstation failed to contact the DHCP server and has gone into apipa mode. The Network Interface Card might be assigned an incorrect driver. Another possible cause of the problem is that the patch cable is not plugged into the Network Interface Card, or is not connected to a switch on the other end. However, it could be that the server has run out of IP addresses that it can assign to clients. You can easily tell if this is the problem by comparing the size of the DHCP address scope to the number of devices on your network that request IP addresses from the DHCP server. But since only some of the workstations have got addresses the problem might be the DHCP server. Start off by doing some ping tests to verify that the DHCP server is able to communicate across the network. If the DHCP server is able to communicate with other computers on the network, then I recommend verifying that the DHCP server has an IP address that is compatible with the scope that the server is configured to assign addresses from. The server itself has to be assigned a static address in the same subnet range, such as 192.168.0.199. If this still doesn’t solve the problem make sure that the DHCP server is still authorized by the Active Directory to lease IP addresses. You......

Dns and Dhcp Overhead

...DNS and DHCP overhead DNS or Domain Name System is a service used by computers to translate human-friendly names into IP addresses. It’s like a phone book for the internet. DHCP or Dynamic Host Configuration Protocol is a networking protocol that configures devices that connect to a network can communicate on that network; it manages things like IP addresses, default routes and DNS server addresses. By using DNS and DHCP in concert, a site can happily grow to hundreds or thousands of nodes servers, desktop systems, laptops, printers, whatever, with minimal network/systems administrator effort. Both DNS and DHCP are essential tools in the network administrator's toolkit for managing all the IP devices on a corporate network. The more devices that require an IP address the more likely you are going to need DHCP and DNS to help maintain the IP addresses. The advantage of using dynamic IP addresses is that you avoid many common problems. For example, if you manually configure IP addresses, you must keep track of which addresses you have and haven't assigned, and to whom. If you accidentally assign two people the same address, of if a user monkeys around with his or her address, you can run into network problems that can be very hard to resolve. Furthermore, in many organizations, it's common practice to constantly move computers all over the building or between buildings. In such situations, if you were using static IP addresses, you'd be forced to change IP addresses to an...

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.

Unit 2 Exercise 1 Dns Scenario

...It is not necessary to put a DNS server in such a small location. 5 users and slow network connectivity does not justify the expense of installing Servers in that location. Unless there is a large amount of File sharing, or other data that needs to be accessed daily by other locations on the network. If that is the case then yes put in the server but configure it as a secondary or ADI zone type. I suggest putting the servers in the other location where you have 30 Users and good connectivity. You can also store all the files from both locations in the larger office, the smaller location can remote in via “VPN”. By doing this all the information from the smaller sight is stored off site. The smaller sight can be run with a smaller cheaper router. The server in the larger more utilized office should be set up as the Primary Zone since it is utilizing a better connection and has more users this is essentially HOMEBASE! If you run DNS on domain controllers, you have the opportunity to use something called Active Directory Integrated zones, or ADI zones. In classical DNS, the zone information is stored in text files that sit on the hard drive. Yes, they’re protected by NTFS, but you don’t have the ability to impose per-record security. You may also want to create an ADI zone; the zone information (and all the associated resource records) are imported into the AD database, NTDS.DIT. The zones and zone records become objects in AD. This has a variety of benefits (and potentially......

Unit 8 – Assignment 1: Dns Zone File

...Unit 8 – Assignment 1: DNS Zone File Assignment Requirements The Just Legal Company in Figmont, Nebraska has acquired a new Internet address – www.justafigmont.com. They want to set up a DNS server. What would a basic DNS file look like? Describe the file. A DNS Server is a hierarchical naming system for computers and resources connected to the internet. Basically each line is a text description that defines a single resource records Domain Name Servers (DNS) are the They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. Information from all the domain name servers across the Internet are gathered together and housed at the Central Registry. Host companies and Internet Service Providers interact with the Central Registry on a regular schedule to get updated DNS information. When you type in a web address, e.g., www.jimsbikes.com, your Internet Service Provider views the DNS associated with the domain name, translates it into a machine friendly IP address (for example 216.168.224.70 is the IP for jimsbikes.com) and directs your Internet connection to the correct website. The Domain Name System is a hierarchical naming system for computers and resources connected to the internet. Basically this is the Internet's equivalent of a phone book that lets you have name to number mappings on your computers. The name decel.ecel.uwa.edu.au is the number 130.95.4.2 and vice versa. This is achieved through the DNS. The DNS is a......

Unit 2 Assignment 1 Dhcp Troublshooting

...Dear Mr Miller I received your email explaining the issue you are having with changing the DHCP scope to match the overall corporate IP address scheme. The problem you are having as I understand it is t that some of the machines picked up new IP addresses. Well I try to follow the moto of “KISS” when I run into a problem of this nature. What this means is I tell myself to “Keep It Simple Stupid” and this reminds me that most of these types of issue can be corrected by the simplest of measures. So if I was to encounter this issue, the first thing I would do is to simply have each of the workstations that didn’t revive a new IP address rebooted. This as you is aware this forces the machine to actively ask for another IP address. Most likely this will solve at least a few of the workstations issue. Then IF you still have workstations that are having problems you might then try double checking to make sure the address scope has enough addresses if not and widen the scope range. Next I would check the DHCP server roll settings. Then if the problem persists you may check to see if it is a router/firewall problem and makes sure you have the service enable. And IF this does not correct your issue you may actually be having either a connectivity or software conflict issue on the workstations that are still having the issue. Please let me know if any or all of these ideas have been of any assistance to you. Sincerely Joe Woodcox....
