City Power & Light has five different locations named Central, Northwest, Northeast, Southwest, and Southeast. The Central location has 500 client computers and two network servers. Each of the Northwest and Northeast locations has approximately 75 client computers and one server computer. Each of the Southwest and Southeast locations has 100 client computers and one network server. Figure 1 illustrates the company's network infrastructure. Figure 1 City Power & Light network infrastructure S1, S2, S3, S4, S5, and S6 are servers on the City Power & Light network. All of these servers run Windows Server 2008, Standard Edition. All client computers run Windows XP Professional. All computers are configured in a single workgroup named WORKGROUP. Andy Ruth, director of City Power & Light, asks you to design an Active Directory infrastructure for the company. He wants everyone to have single sign-on capabilities to every server in the network. He tells you that all users use the same applications and have roughly equivalent configurations. He thinks that the 56 Kbps links are a little slow for the company, and he wants to have control over traffic sent across those links. However, the T-1 links can handle more traffic without a problem. Andy tells you that no special security needs require isolating any of the remote locations from the central...

...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 hope some of this...

...Part A - Narrative and Bridge Troubleshooting Electric Circuits. Narrative I have always had an interest in finding out how all things electrical work. From a very young age I started to fix things electrical around the house and started hooking up house and car stereos and recievers. Once I got my first computer I st had to know how it worked. So I took it apart and ending up trashing it. But that fine day my interest in circuits and circuit boards grew. As I grew older and he computers became more advanced, I knew things could short out more and I had to learn how o fix these things. So I started to study and look into the details of these electronics and how they worked. I wanted to know how these things worked and if something went wrong could I fix it. Most importantly I could get a better understanding of why the circuit fired. It was a lot of fun figuring out and fixing the problem myself. When listening to music that had a little too much wattage hook up to it, or the sub woofers was too much wattage and had fried all the speaker channels. I had to order new channels and fuses, the fuses where easy to install but taking everything apart to get to the channels on this kind of old school reciever was a little difficult. BRIDGE What I would like to learn more about is the fault point of an electrical circuit in different items. And what are the symptoms of the failure? I know that if you over-clock a computers processor to much it will overheat...

...DHCP Troubleshooting Each subnet can have only a single DHCP scope with a single continuous range of IP addresses. To use several address ranges within a single scope or subnet for the DHCP service, you must first define the scope and then set any required exclusion ranges. Use the entire range of consecutive IP addresses that make up the local IP subnet for which you are enabling the DHCP service. Set exclusion ranges for any IP addresses within the scope that you do not want the DHCP server to offer or use for DHCP assignment. By setting an exclusion range for these addresses, you specify that DHCP clients are never offered these addresses when they request an IP address from the server. Excluded IP addresses can be active on your network, but only by manually configuring these addresses at hosts that do not use DHCP to obtain an address. To create a new DHCP scope: 1. Open the DHCP Microsoft Management Console (MMC) snap-in. 2. In the console tree, double-click the DHCP server you want to configure. 3. Right-click IPv4 or IPv6 and then click New Scope. 4. Follow the instructions in the New Scope Wizard. Before you create the scope, determine starting and ending IP addresses to be used within it. Depending on the starting and ending IP addresses for your scope, the DHCP console suggests a default subnet mask useful for most networks. If you know a different subnet mask is required for your network, you can modify the value as needed. When you finish creating...

...DHCP Troubleshooting 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 From IT Admin: To: Junior Admin: A scope must be defined and activated before DHCP clients can use the DHCP server for dynamic TCP/IP configuration. DHCP servers do not communicate scope information with each other, you must be careful to define scopes so that multiple DHCP servers are not assigning the same IP address to multiple clients or assigning addresses that are statically assigned to existing IP hosts. A DHCP server can only service requests for a scope that has a network ID that is the same as the network ID of its IP address. Use the display dhcp server tree all command to verify that an address pool containing or residing on the same subnet as the subnet of the receiving interface’s IP address is configured. The DHCP server assigns IP addresses with leases (support for lease duration depends on the device model). If an IP address has passed its lease duration, the DHCP server does not assign the IP address. Execute the display dhcp server ip-in-use...

...Introduction to Personal Computers Arthur J. Teufel III TB143 I own two personal computers, particularly a desktop and a laptop. Both of these PC’s are running Windows XP Media Center Edition 2005. The desktop, an HP M7250N, was purchased in April 2006 and the laptop, a Toshiba M105-S3004, was purchased in June 2007. Both PC’s were purchased new. At first both units performed very well with no long term issues. Approximately two months after the purchase of each computer, I noticed that they were failing to automatically install several updates from both the Windows Update and the Microsoft Update sites. These updates included various security and root certificate updates. The updates were able to download to my computers, but the installation itself had failed. The only changes that had been made to the computers were the installation of updates, some games, Microsoft Office 2003, and some utility programs. Regular maintenance (disc cleaner and defrag) had been performed nearly weekly. My first course of action, per Microsoft’s instruction, was to click a link on the update site which, referencing a specific error number, took me to a search of the Microsoft Knowledge Base. Unfortunately, I was unable to find any Knowledge Base articles that specifically addressed failed automatic updates. My next attempt to gain a clue was to search Microsoft’s entire Knowledge Base as well as Tech Support forums for a mention of “Failed Automatic Updates installation...

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 --- Dear Junior Admin, A common problem that happens more often than not is assuming as soon as DHCP options are changed that all PCs will automatically implement them. It sounds like this may be an example of that exactly. With DHCP when the computer comes online it does a broadcast search for a DHCP server. The server responds with a message offering an IP address, subnet mask, and default gateway as well as some DNS options and WINS if that is configured. Once the pc accepts it the DHCP server will send an acknowledgement message. At that point the PC will send back a message that it will take it and the DHCP server will send a message indicating that an IP address has been reserved for the lease period. At this point the PC will not contact the DHCP server again until halfway through the lease time, which is usually a default period of 8 days. If you want to force all of the PCs to grab a new IP address then you will have to go to each computer, open a DOS prompt, and...

...Troubleshooting Graphics Drivers A user asks you to troubleshoot his Windows 7 workstation, which is behaving erratically. He has recently purchased and installed a new graphics adapter. Since then, he sees occasional wavy lines on the display. You run Device Manager on the system and note the manufacturer, model, and version number of the device driver for the graphics adapter. Then, you check the adapter manufacturer's website and discover that there is a new driver available for the adapter. After downloading and installing the driver update, you restart the system. The system appears to start normally, except that the graphical interface has been replaced by incomprehensible noise. Because you cannot see the display, you cannot work with the system. Explain the following: • Describe the problem. • What should you do to return the computer to an operational state? With a graphics adapter if after installing the update and the system is nonfunctional it is most likely caused by a bad driver. First thing you should do to return the computer to an operational state is unplug the HDMI or VAG wire from the graphic card and plug the VGA wire of the monitor to the VGA port on the motherboard. Then you need to troubleshoot the driver. First thing you can try is opening the properties sheet for device and check the device status. You can launch a troubleshooter from here. If you are unable fix the problem from here the next thing you can try is to open the device manager and...
