    Starnge DNS(?) Issue

    Here’s a stumper:

    At my wife’s work, there is a Web site (www.humana.com) that will not resolve. Any other Web site they attempt to access does resolve. If I ping the site, I get a good return. Also, I can access the site from any other location (home, lab).

    When I ping from her office, the IP I get takes me to an incorrect Web site. If I ping from here, it fails to resolve (and gives me a different IP address!?).

    Very odd. Sounds DNS related, but damned if I know what it is. Maybe a bad cache?

    Any ideas?

    Sounds like a bad entry in dns. quick resolution would be to add the entry to the host file of the computer. Do you have access to the dns server?

    Kind of my thinking too. Sadly, no, I have no access.

    You can add to hosts file of client machine. Looks like your wife work's DNS machine is getting the wrong cache and not updating it regularly.

    See, this is the major shortcoming of DNS. When things get okay, no problem. When any one DNS sever have screwy setting, then all of those server which update against that server got all screwed too.

    Also, try doing

    Code:
    ipconfig /flushdns
    ipconfig /registerdns
    This will force the client to get the latest dns records.
