    Hello,
    I have a Win2000Pro machine that can ping out to any location on the
    Internet, including DNS servers, but:
    1. It cannot go to sites by IE6.
    2. It cannot ping sites (e.g., www.yahoo.com) by name.
    3. It cannot find DNS servers for nslookup
    Also, it is on a small Lan with other computers that can get to the
    Internet by IE6.
    I have used the latest Ad-Aware to remove junk.
    Also, Norton Anti-Virus reports (recently updated) that no virus is
    found.
    There is no software firewall on this machine, yet, it is acting
    like ports 80 and 53 are blocked.
    Any suggestions?
    Rich

    Check your HOSTS file @ c:\winnt\system32\drivers\etc\hosts for rogue entries

    You can install a packet sniffer on the computers and see what's happeing
    with the packets. You have a few you can choose from but most go with
    Ethereal.
