    First, I'm working on an Acer one netbook, running xp.

    I was fighting the latest version of the Security Sphere virus for the past few days, and after downloading malwarebytes and an avast trial, I was able to wrangle (I believe) the virus off my computer.

    However, in the process, my ip address seems to have been lost. It's currently at 0.0.0.0 I tried to repair, but it would not connect. second I attempted ipconfig/release but get the error message: "No operation can be performed on Local Area Connection while it has its media disconnected. IP Address for adapter wireless network Connection has already been released."

    I checked to make sure that ipconfig was in the correct file, and created a new path in environmental variables, but nothing was changed.

    I checked and it is set to "Obtain an IP address automatically" and "Obtain DNS server address automatically" as well.

    I also went through control panel > internet options > connections and "Use a proxy server for your LAN" was unchecked.

    I went to where wifi was available, but I am facing the same problems. Both LAN and wifi do not work.

    I'm running out of ideas, and with a 10 page research paper due tomorrow, I need to figure this out fast. I'm running out of ideas, and Any help would be appreciated. Thanks

    Sometimes after a malware battle it is very difficult or impossible to get networking straightened out. But, hoping for the best ...

    (from a JohnWill post)

    IP addresses of 0.0.0.0 are normally caused by one of the following.

    Diagnosis:
    1. DHCP Service not running.
    2. Duplicate IP address on the network.
    3. Bad NIC card drivers.
    4. Defective NIC hardware.

    Resolution:
    1. Check Control Panel, Administrative Tools, Services. The DHCP Client service should be Started and its Startup Type should be Automatic.
    2. Turn off ALL of the computers and other network connected devices, reboot the router, then restart all the computers and other network devices.
    3. Check for upgraded drivers and/or reload the Network drivers.
    4. Replace the Network Interface Card.

    Edit -

    Noticed TerryNet beat me to it - follow his advice first and post back results he requested




    i suspect the virus may gave affected the dhcp client dependencies

    check the dhcp client by doing the following

    also check the other services


    ------------------------------------------------------------------------
    Services

    We would like to see some status information for each of the services listed below to do this goto
    Control Panel>
    Administrative Tools>
    Services>

    then for each of the servies listed below - Please post back the following status information -
    If the service is Started/Stopped
    and
    If the service is Automatic/Manual

    • COM+ Event System (for WZC issues)
    • Computer Browser
    • DHCP Client
    • DNS Client
    • Network Connections
    • Network Location Awareness
    • Remote Procedure Call (RPC)
    • Server
    • TCP/IP Netbios helper
    • Wireless Zero Configuration (XP wireless configurations only)
    • WLAN AutoConfig (Windows 7 & Vista wireless configurations only)
    • Workstation


    If a service is not running,
    right click on the service
    then click on properties and now check the dependencies.

    Check each of the dependencies and see which one is preventing the service from running.

    Also to help us identify what may be causing the issue
    Check the event log, there may be clues to what is failing. To do that
    Start >
    control panel >
    administrative tools >
    event Viewer>

    Terrynet,
    Thanks for getting back to me. I checked the DHCP client, and it was marked as Automatic, but it was not started. When I attempted to start, I got an error message saying "Could not start the DHCP client service on local computer. Error 1075: The dependency service does not exist or has been marked for deletion"

    See etaf's post for how to trace the dependencies back.

    DHCP is running on the following dependencies
    1. AFD
    - TCP/IP Protocol Driver
    - IPSEC driver

    I also just checked the logs, and it looks like I'm getting two consistent Service Control Manager errors, one right after the other.

    1. The DHCP Client service depends on the following nonexistent service: NetBT
    2. The TCP/IP NetBIOS Helper service depends on the following nonexistent service: NetBT

    To verify that the dependency components are running. Follow the steps below:
    • Click Start, Run and type DEVMGMT.MSC
    • In the View menu, click Show hidden devices
    • Double-click Non-Plug and Play drivers section
    • Double-click the entry NetBT and click the Driver tab
    Whats the startup type set to ?
    • Start the service. Note down the error message if any.

    Post back if all are started and any error messages
    --------------------------------

    i suspect it may be the virus - so have a read here http://forums.techguy.org/virus-other-malware-removal/943214-everyone-must-read-before-posting.html and depending on above - we can move to virus forum and then post all the logs
