    Hi Guys

    I need help. I was brought a comp that had XP Pro installed. It wouldn't open windows except in Safe Mode. I installed Malwarebytes onto a cd and installed it in Safe Mode and ran it. I found 22 Trojans. Then it opened regular mode and I downloaded Spybot S&D and ran that for another 15 Trojans. I ran it again and got another 4. Next time it ran clean. I rebooted but then It wouldn't find the ip address. I have done the ip release and renew. I go to Run to find IP address but it shows nothing. The DHCP is on automatic and started.

    I have Googled the problem and there are many suggestions but I have to get on the internet to use them. I can't get there. I have another computer on that router that runs IP 192.168.1.---. It runs good.

    I have changed router cord to the computer. I have changed router outports. I have plugged the router source that's in question into the good computer and it still works. It seems everything to the computer is working properly. I know I'm missing something but in 18 years, I've never run into this. What's the key? Thanks.

    Tom

    I suspect you may still have the virus/malware or it has corrupted some of the network files

    lets start with a couple of things - lets see an ipconfig /all and also a tcp/ip reset - see below



    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

    We would like to see the results from ipconfig /all post back the results in a reply here

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results to notepad and then automatically open notepad.

    Now all you need to do is copy and paste those results to a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste
    ------------------------------------------------------------------------

    and press enter

    Reboot the machine.

    Please note and post back - if you receive the message

    Post back the results here
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Safemode with networking
    with a cable connected from PC to router
    check the cable - see if there is a light on the router accosiated with the cable port used , also check if you have a green/yellow light on the PC LAN port
    - try safemode with networking
    as the PC starts keep tapping F8 - a menu appears - choose
    safemode with networking - see if that works

    i'm sorry Etaf. My isp has been shut down. I called them and they said it's because of these110 k/hr winds and they will be up soon. I will try that when I can get back on.
