    Hello,

    This PC has lost browser features because DNS has ceased to function. I can ping an external IP address, however DNS queries are met with the response "Ping request could not find host <URL>. Please check the name and try again." A VM on the same machine has no problem. Is there a root DNS utility on the host platform and a way to diagnose it. Thanks very much,

    Joel

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Is that DNS (50.17.153.47) your ISP's or one you specified? Either way it may be not working properly. Try a free public DNS server.
