    Agent and Opera only net applications
    ISP (ISDN-64k)

    Problem is that DNS resolving stops for no apparent reason
    I can via a DOS window, still ping the DNS servers by ip
    but no name resolving !

    Restarting ISP connection doesn't solve the problem
    Neither does restarting the appications.

    I have to reboot every time
    and as it works after every reboot I can't see how it can be an ISP

    I run several anti ad/spy scans - nothing found

    Though this still seems the most likely (to me)

    Any ideas how I can detect the offender / prevent the problem ?

    and in the mean time anybody got a solution ie stops/start some
    process that saves me having to reboot !!

    It probably isn't an ISP issue (and not a malware problem either). I had
    the exact same problem with the same configuration (Windows 98 SE, ISDN)
    and different ISPs.
    Actually, the DNS resolution did not stop entirely, it simply took very
    long (up to a minute to resolve a host name).

    I never found a solution so I learned to put up with it and simply
    blamed it on Microsoft. As usual.

    The problem I ran into on Win ME with DSL service was something along
    these lines:


    where I experienced rather random delays of about 45 seconds
    before getting a response while on line. I did try the RASPPPOE
    sw mentioned, and it fixed the problem, but later I decided to
    try the simpler way of simply entering IP addresses under
    Configuation - TCP/IP Properties - IP Addresses

    Even though I have dynamic IP assigned, putting in any valid
    IP of my ISP's domain worked fine. I once had a web page
    dedicated to this form of the fix that worked for me.

    Since it's actually a DNS resolution problem, the simple fix might
    work for other situations, and not just DSL. I dunno.
