    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., 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
    There is no software firewall on this machine, yet, it is acting
    like ports 80 and 53 are blocked.
    Any suggestions?
