Troubleshooting Procedures
ITT Institute Virtual Library; Method and System for performing simplified troubleshooting procedures to isolate connectivity problems. “Initializing the proxy client module with the identity of a VLAN on which the client computer is connected and which an IP address of the end station in a network, with the client IP address and client MAC address, the identity of the VLAN and the IP address of the end station provided by a remote computer coupled to the third port of the switch; disabling the first port of the switch; with the proxy client module having a logical interference with the VLAN and utilizing the IP address of the end station in the network. The client IP and client MAC addresses and the identity of VLAN provided by the remote computer to: 1) assign the client IP address + MAC addresses to the logical interface with VLAN 2) Run a sequence of connectivity tests with the end station when the first port is disabled. 3) Reporting the result of the sequence of connectivity to facilitate identification of the reasons packets are being dropped; a) Determining whether the connectivity problem is on the switch or on a link in the switch b) Identify the reason for the packets being dropped c) Identify two features responsible for dropping the packets, such as failure to respond to Address Resolution Protocol (ARP)”

Creative Process in Aircraft Troubleshooting

...Creative Process in Aircraft Troubleshooting Trevor G. Bryant PHL458 December 3, 2012 Donald Linville Creative Process in the Aircraft Troubleshooting World In all my years in the Air Force nothing made me more excited than troubleshoot an aircraft weapons system malfunction. Discovering what caused the problem, where that particular problem was on the aircraft and coming up with the final solution gave me such pride in what I did on a daily basis. What was best was when I was working on the A-10A aircraft. This was not the high tech computer heavy aircraft in today’s Air Force. This was a “hard-wired” jet that had little to no digital capabilities. To troubleshoot these took time tracing faults through wires and reading wiring diagrams and schematics. I spend many times inside a Hardened Aircraft Shelter with a multi-meter and a book in front of me, checking for voltage and continuity in wires. It came natural to me and I never thought of the processes that I used to accomplish the troubleshooting. As I look back on these times, I was definitely using a creative process to fix these ailing aircraft, and it was very simple in the way things flowed. Troubleshooting Defined Basically troubleshooting is finding a way to fix a know problem. Webster Dictionary defines a troubleshooter as “a person skilled at solving or anticipating problems or difficulties” or “a skilled worker employed to locate trouble and make repairs in machinery and technical equipment”......

Collaborative Troubleshooting Operating Systems

...Collaborative Troubleshooting Operating Systems Introduction Working in technical support role within an IT department of a major organization requires someone with knowledge of various operating systems and ability to troubleshoot the problem methodically. A good technician can use his knowledge to accurately diagnose, pinpoint the problem, and solve the issue. Scenario 1 You have recently started in a new technical support role within the IT department of a major manufacturing organization. Your first support call is from a client who is using Windows ME® and has encountered stability problems. Discuss the process you would undertake to identify his or her problem and the operating system’s tools that you would use to do so. In order to determine the cause of the instability you may need to probe the client and ask questions to help pinpoint the problem. Did the user receive any error messages? Is the computer just generally running slowly? Did the client recently install additional software or hardware? If the client is unable to help answer questions then a process of troubleshooting steps may need to be taken to solve the instability issue. Start with the booting up the computer and checking for any error messages during Power-On Self-Test or POST and that maybe BIOS related. Sometimes BIOS can let you know that a piece of hardware isn’t being detected properly. You may need to enable a device or setting which can be fixed in the BIOS setup. Check......

Dhcp Troubleshooting

...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......

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 ...

Dhcp Troubleshooting

...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......

Chapter 10: Ethernet Switch Troubleshooting

...Chapter 10: Ethernet Switch Troubleshooting Troubleshooting is very important for a CCNA technician. In this chapter we see tools and methods that will help you identify and solve most network problems. Consider using the techniques in this chapter as a guide to logical problem-solving processes. The steps in this tutorial address computer connection problems in Cisco Command-Line Interface (CLI). The process of troubleshooting help you the problem or the issue you are having. It makes you think in all the possible causes of it and test your skills as technicians. There are three basic steps in the troubleshooting process: Analyzing/Predicting normal operations-in this step you basically predict what should happen if the network is working correctly, based on documentation, configuration, and show and debug command output; Step 2: Problem isolation-Determine how farer do the packet can go and show and debug command output; Step 3: Root cause analysis- Identify causes of the problems identified and how can be fixed it. The documentation and the show command output are helpful in this process to confirm network topology and predict its normal behavior. Isolating the problem at Layer 3 point out what went wrong in Layer 1 and Layer 2. The more supportive components in this process are Cisco Discovery Protocol (CDP), Examining interface status and Analyzing where frames will be forwarded. CDP lend a hand to discover and/or confirm documentations by......

Dhcp Troubleshooting

...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 through 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......

Troubleshooting Electric Circuits

...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......

Best Practices for Network Troubleshooting

...Best Practices for Network Troubleshooting Valance Baltimore NTC/405 July 27, 2015 Bradley Rush Best Practices for Network Troubleshooting The article that I found is titled Top 10 Basic Network Troubleshooting Tools Every IT Pro Should Know (2011). This article list ten basic troubleshooting tips that could help an IT professional determine the reason for a failed network connection. Let’s start with the most commonly used network tool, Ping. The Ping utility is used to provide a connectivity test between the requesting host and the destination host. Ping is done through the Internet Control Message Protocol (ICMP), by sending an echo packet to a destination host and then listens for a response from that host. This utility is used to help determine where the connection problem may be, in the office or within the network provider’s network. After the Ping utility has been performed to determine the basic connectivity, and then typically the next step would be the tracert/traceroute utility is used. This utility can determine the path to the destination host and the route the packet takes to get there, and the response time of the intermediate host. Tracert is window based and traceroute is Linux based. According to Wilkins (2011) one of the most important things that must be completed when troubleshooting a network is to find out the specific IP configuration of the affected hosts. If the address is configured statically you may already know this information, but...

Troubleshooting Graphics Drivers

...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......
