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…...

...Unit 2: DHCP Troubleshooting Dear Junior Admin, Based on the what you have told me regarding the DHCP scope the overall corporate IP address, it sounds like you have a lease time settings which is probably set to renew ip addresses at the default times. 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 2 The Internal Use Only data classification standard of Richman Investments has many different infrastructures domains that are affected via internal use only data classification. More than all others, the three infrastructures that are affected the most are the User Domain, Workstation Domain and the LAN Domain. The reason why the User Domain infrastructure is one of the most affected infrastructures is because the User Domain infrastructure is the infrastructure that allows users to access the network. This is a problem because many users do not fully understand everything, all the time and thus is bound to make a mistake sooner or later. With so many users on our network, this is probably the most vulnerable domain infrastructures in our network. The Workstation Domain is also another domain infrastructure that has great reason to be affect by internal use only data because this is where the user connects to the our network. The reason that this can cause security threats and other problems is because this domain can be connected via a personal laptop or even a cell phone or other mobile device. The final infrastructure domain that is greatly affected is the LAN domain. The reason that this domain infrastructure is affected by internal use only data is because this domain is the open domain available companywide, to anybody in the building or even near the building via a wireless device. If we watch these specific areas closer and implement some......

...IS3340-WINDOWS SECURITY | Recommendations for Access Controls | Unit 2 Assignment 1 | | [Type the author name] | 4/3/2014 | | Access Control is the defined as “the selective restriction of access to a place or other resource”, in the RFC 4949. “The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.” Simply put the ability to read, write, modify, or deleting information or files is what Access Control is. It is more than this, in the permissions (authorization) granted to each Security Group or Individual User. The permissions mentioned in the previous paragraph are rights that a user is allowed to access, create, modify, or delete the file(s) inside a file folder, or objects. These are all permissions (authorizations) controlled by the Authorized Windows Security Personnel of the file structure. We will list some examples of how this outlined and what the impact would be, but first understand that requirements for the permissions is controlled from the Group Level, other than by Individual User, because it is easier to control from a security standpoint when you want to modify these abilities. There are four folders created (D:\ERPdocuments, D:\ERPdocuments\HRfiles, D:\ERPdocuments\SFfiles, D:\ERPdocuments\MGRfiles) which we want to allow specific permissions for certain functions (tasks). For example; by modifying the permissions under the specific user account for HRmanager to include...

Dhcp Troubleshooting

...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......

...Eric Satchell NT1330 Service Provider Types Unit 2 Assignment 1 July 3, 2014 Comparing Service Providers There are a lot of companies providing services, but AT&T provided telephone communication to the public. AT&T monopolized the telecommunication industry until the United States took them to court for antitrust and won. AT&T was broken up into eleven smaller companies, call Baby Bells. One of the companies that derived from this law suit was the Regional Bell Operating Company or RBOC. RBOC was a term that described one of the US telephone companies that provided telephone, telegraph, and long distance to the consumers. RBOC is part of a local exchange carrier allowed to compete for business. RBOC services internet service which in turn dealt with digital data. The merging companies provided different types of service based on the Telecommunication Act of 1996. ILEC or incumbent local exchange carrier is a telephone company that provided local telephone communications before the ruling to break up the Ma Bell Company. The FCC ruled that the ILECs must provide other telecommunications service providers access to their equipment to be able to provide a better rate to the consumer. This......

...Introduction to Networking Unit 2: Assignment 1 Indentifying Network Topologies Identify the major needs and major stakeholders for computer networks and network applications. The major stakeholders for computer networks and network applications are the ones who use it or relay on it to do business. The main stakeholders are the ones who uses the network or applications to get their work done for their company. The next stakeholder is the company or people who rely on the first company to get what they need. The ones who design the applications or the network are stakeholders in the fact they need to make sure their work is done properly so others can do their job. The owners are also stakeholders in the fact that others rely on their people and software to get their work done. Then there is the end-users who are also stakeholders because we need the network and applications to do our daily job. Identify the classifications of networks and how they are applied to various types of enterprises. PAN (Personal Area Network)—personal. You as an individual and the range is around that person LAN (Local Area Network)—network of interconnected computers within a small geographic area. Area of LAN’s are a room, building or group of buildings, offices, schools. The range is 10m – 1km MAN (Metropolitan Area Network)—a network design for a town or a city.

It was one of the United States regional telephone companies that were created as a result of the breakup of AT&T. They are allowed to compete for long distance telephone traffic under certain circumstances. RBOCs are generally in competition for digital data and internet traffic with wireless service providers and cable TV companies. ILEC is short for incumbent local exchange carrier. IT is a telephone company that was providing local service when the Telecommunications Act of 1996 was enacted. They are in contradistinction to CLEC. GTE was the second largest ILEC after “The Baby Bells” but has since been absorbed into Verizon. CLEC stands for competitive local exchange carrier. IT is a telecommunications provider company competing with other, already established carriers. CLECs have evolved from the competitive access providers that began to offer private line and special access services in competition with the ILECs beginning in 1985.

...10/ 1/ 2014 NT2580 Unit 2 assignment 1 The workgroup consists of three primary workgroups, which contain group membership lists of users within the Active Directory infrastructure that currently exists on the SMB Server that is located within the confines of the LAN structure. The security breach, which is defined as any event that results in a violation of any of the CIA (confidentiality, integrity, availability) security principles, was caused by the SMB server being accessed by an unauthorized user due to a security hole that was detected by the server software manufacturer the previous day. The security patch will not be available until possible as long as three days, but hopefully within that timeframe. In addition, the LAN administrator needs at least one week (minimum) to download, test, and install the patch. To calculate the Window of Vulnerability (WoV) for this security breach, the following timeline will be used as a guideline to determine the basis for calculation: First it is important to understand the variables considered in this timeline formula. The WoV is the period within which defensive measures are reduced, compromised, or lacking. The WoV covers a timeline from the moment vulnerability is discovered and identified by the vendor. It also includes the time taken to create, publish, and finally apply a fix to the vulnerability. It is also important to explore the device(s) that were targeted by the attack.

...NT1310 Week 2 – Unit 2 Assignment 1 Service Provider Types There are five different types of telecommunication types to date. First of which is RBOC – (regional bell operating company) which was a telephone company created as a result of the breakup of AT&T. The seven original regional Bell companies were Ameritech, Bell Atlantic, BellSouth, NYNEX, Pacific Bell, Southwestern Bell, and US WEST. The reason why this was so important was because these companies are what provided local telephone service while AT&T provided the long distance phone service. These are what made up the Local Exchanges or the LEC’s. ILEC or incumbent local exchange carrier was a telephone provider that provided local service prior to the telecommunications act of 1996. These play a major role because these carriers are what own the local loops/exchange and facilities in that area. CLEC’s are the exact same thing except they are the competitor to the ILEC’s but provided their own networking and switches for local service. MSO or Multi system Operator – is owner of multiple cable and satellite television systems. This ties into what an ISP is. An ISP is simply and Internet service provider that provides a mean for accessing the internet. MSO is majorly known for being cable companies, because of this cable companies are providing internet to cable customers (usually as bundles with their plan). They work within each other because......

...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......

...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....
