    I still have networking issues on one of my PC's. I have just discovered
    I cannot ping localhost or 127.0.0.1

    The MB is MSI with onboard LAN.

    What should be my next step to try and fix.

    You're kidding right?
    What OS was the machine running?
    How long has this problem existed? (ie. since install.. since an event..
    or recently for no reason at all)
    Not being able to ping 127.0.0.1 or localhost normally means the TCP/IP
    protocol stack hasnt been installed (properly)
    Also give your drivers the once over

    It's more likely that there's some overzealous firewalling going on.

    Or some LSP has borked.
    OP, tell us your Operating System. If windows of some sort, look here for
    info on how this happens usually.
    http://www.doxdesk.com/parasite/
    and
    https://netfiles.uiuc.edu/ehowes/www/main-nf.htm

    LSP fix is available here:

    Yeah! Gentle people there are several OS which are in fact capable of
    networking.

    Please always state one OS (platform) when asking questions such as this.
    It does help.

    Sorry, a real newbie moment. Sorry for the lack of pertinent information

    Windows XP SP1
    Was running okay for a long time - 4 months with no issues
    I have restored the system back 2 weeks and the problem persists
    No firewall installed. Local network has firewall installed in front of
    cable modem
    Ran Spybot and Adaware and no results but definitions were 1 month out
    of date
    I have a home network with DHCP at 192.168.1.1
    3 other PC's on the network have no issues including one laptop
    connecting to the wireless access router with 4 port switch
    I changed the network cable just in case. No change.

    How do I restore the TCP/IP protocol stack?

    What is the best methodology to debug networking (or lack of it) issues?

    grr its XP (of which my knowledge has been shown to be lacking)
    heh and its a can of worms (the problem not the OS [ dont want to start a
    flame war here])
    you want to check NICs' havent died (both ends of the
    cable)
    make sure no MAC's clash (unlikely as your network was up
    previously)
    make sure the drivers for your card are OK
    treble check for Virus/Spyware (Id even go so far as to say swap out the
    HDD with another to see if its Hardware or Software related.. or
    use Knoppix or other Live CD/floppy etc)
    if that machine comes out rosey and the OS checks out.. time to move on to
    the DHCP server and treble check that hasnt been 'interfered' with
    after all that take two aspirin and call me in the morning :)
    first job though is finding where the problem lies... then you can work on
    fixing it
