    I'm trying to figure out why a network connection to a Vista DNS server
    fails. When I Google, I discover that NT DNS had an exploit. Is it known
    that the Vista DNS server is secure? All my updates are up to date. Thanks.

  2. There's no such thing as a Vista server. What OS is your DNS server running

    Thanks for correcting me. DNS cache client service runs on all Windows
    systems, since when?

    I have two Vista Ultimate systems. I've extracted the following from the
    management consol for the DNS client service:

    "The DNS Client service (dnscache) caches Domain Name System (DNS) names and
    registers the full computer name for this computer. If the service is
    stopped, DNS names will continue to be resolved. However, the results of DNS
    name queries will not be cached and the computer's name will not be
    registered. If the service is disabled, any services that explicitly depend
    on it will fail to start."

    I've provide you with this fragment because I can't lay my hands on original
    technical documents that started me on this work and which stated that the
    DNS cache was accessible by other computers. I've opened up my router to
    pass DNS queries on port 53. I'm trying to verify that my DNS client service
    is accessible from the other side of my firewall.

    I posted my original question seven hours ago. Since then I have determined
    that the failure of my network connection had no bearing on my attempt to
    access my Vista DNS client service from the other side of my firewall. If I
    have feather problems tomorrow, I'll submit another question.

    Come to think of it, I should be able to verify that DNS is accessible by
    assigning the DNS IP address of one PC to that of the other on my side of
    my firewall. If that works I can take my laptop to another location and
    verify that my router passes DNS queries on port 53.

    Thanks for the help. It always helps to clarify ones thinking by asking

    I'm still concerned about the recurrent failure of my network connection
    which is through a Dlink DWA552 in Vista. This problem does not arise in
    Windows 7. I've submitted question of technical support at Dlink and
    Microsoft but I have not yet received answers.

    I am loath to commit to Windows 7 because I prefer Vista.

    My original question seven hours ago was submitted on the other side of my
    firewall in an internet cafe. I was able to reboot my router remotely but
    that did not solve the problem, which is intimately connected to the
    interaction between Vista and my DWA552.

  4. Read inline please.

    The DNS Client is not and should not be accessible by other computers. You
    can view the contents of the DNS Client cache by using ipconfig /displaydns
    in a Command Prompt.
    Are you using the D-Link Drivers or the Drivers from Windows Update?

    I run a IIS server and an FTP server on Vista Ultimate. It runs fine. I
    cannot get FTP to work on Windows 7 beta.

    What you say about the DNS server/client in Vista Ultimate 64-bit seems to
    be confirmed by experiment. I also have Windows 7 beta 64-bit on another
    partition. The management consol for Windows 7 beta Event Viewer, displays
    events for both server and client. I will boot Windows 7 and try to same
    experiment to access the DNS server and let you know the result.

    This is the email I set to both Dlink support and Microsoft support:


    I have a DWA552 that is hard to manage in Vista. I also run Windows 7 trial
    which has a new Windows device driver 'vwifibus.sys' that is installed in
    conjunction with Atheros device driver 'athrx.sys' for the DWA552. With the
    two device drivers the performance of the DWA552 is rock solid perfect 24/7,
    with extremely high bandwidth potential. However I do not like Windows 7
    trial. I would like to know if Dlink plans offer a device driver installer
    for Vista that installs both? I found that 'vwifibus.sys' is present in
    /Windows/system32/drivers/ in Vista, it is just not installed either by your
    device driver installer or by Vista. Thanks for you attention.

    That would be a question for the Windows 7 beta newsgroup. But what I can
    say it to test it by FTP to the localhost from the Windows 7 machine itself,
    then try with it's own IP address. Keep in mind, IP configuration should be

    Hi Dan,

    The link Kevin provided stated the vendor driver does not work properly, and
    to simply allow Vista to put in its own driver. You can do that by
    uninstalling the current driver in Device Manager, then restart and let
    Vista find it on its own and put in its own driver.

    Try that out and post back with your results.

    I have booted my Windows 7 64-bit partition. I have performed an experiment
    to see if Windows 7 beta will provide DNS service to my other Vista Ultimate
    PC. My experiment failed. However, this had no effect on the functionality
    of my IIS or FTP servers.

    While running Windows 7 beta I tackled some unrelated device issues. I was
    able to obtain device driver support for my HD camcorder in Windows 7 beta
    that did not work in Vista. My appraisal of Windows 7 is starting to
    improve. Windows 7 also gives rock solid 24/7 high bandwidth wireless
    network connectivity in support of internet TV and internet servers.

    I also have an Xbox 360 on my wired/wireless Dlink network. Vista supports
    Media Center better than Windows 7 beta.

    I also have a Linux box on my wired/wireless Dlink network. Running a DNS
    server on a Linux box is accepted practice, I think. Should I forget about
    running a DNS server on Windows and focus in Linux instead?

    Thanks for your help.

    I already tried that. It does not work. Vista only installs the Atheros
    device driver 'athrx.sys', it does not install the Microsoft device driver
    'vwifibus.sys' that Windows 7 installs automatically. The DWA552 works
    flawlessly, 24/7 with high bandwidth in Windows 7 trial.

    Microsoft device driver 'vwifibus.sys' is found in in
    /Windows/system32/drivers/ in Vista, but it is not installed automatically.
    If you can tell me how to install it manually, my evaluation of Vista will
    improve and I will not need to migrate to Windows 7.

    Thanks again.

    The DNS Server service is provided only on Windows Server operating systems
    (Except Web Editions) and has never been included on a Windows desktop
    operating systems. BIND does have versions that can be ran on Windows
    desktop operating systems.

    As Kevin said, and I agree with, there is no DNS server service that runs on
    a dekstop. So I am not entirely sure what you mean by allowing a DNS server
    service to run on Windows 7 or Vista, unless you are referring to running
    BIND DNS on Windows 7 or Vista.

    Are you possibly talking about ICS (Internet Connection Sharing)? If so,
    then that is not a DNS service either. With ICS enabled, it makes a Windows
    7, Vista, XP, 2003 or 2000 machine act as a NAT gateway, and will create a
    mini DHCP service that gives out a config with the DNS address that exists
    on the outside interface, and will proxy andy DNS requests to the DNS
    address configured on the external interface.

    Sorry to hear it didn't work. I think the WDM is different with WIndows 7
    and Vista, but I can't attest to that. To change drivers, not only do you
    need the .sys file, but an .inf file to tell the OS how to install it. Is
    there an inf file associated with that sys file?

    Thank for your help Are you referring to BIND:

    I am running 64-bit Vista Ultimate on a three drive RAID 0 system. It is not
    a desktop PC.

    There is an option in "Turn Windows features On and Off", "Subsystem for
    Unix based systems". If I install this option can I run BIND?

    I've requested that the software engineers at Dlink and/or Atheros put some
    thought into the problem. It is hard to get their attention. I'm pretty sure
    that I am entitled to software support from Microsoft but I have never got
    past the low level people who do customer support.

    Perhaps this is the place to tell an interesting story. I managed to shoe
    horn Vista Ultimate 32-bit onto a 2003 Dell Inspiron 5100. It is now a
    hardware software dream machine except for the graphics. ReadyBoost really

    I connect to my Dlink wireless router using a Dlink DWL-G630 wireless
    adapter. Under Windows XP Pro the DWL-G630 never worked well and the Dlink
    AirPlus G wireless Utility never worked at all. At one point it was so bad
    that I threw the G630 into the garbage thinking it was toast. Then I changed
    my mind. Now under Vista the G630 and Dlink Utility work perfectly. The
    adapter give me rock steady 54Mbps 11g connectivity 24/7 and the Utility
    works so well that I can scan 11 channels and manage other wireless routers.
    It helps to spread wireless routers across the 11 available channels so that
    they don't interfere. This can only be manually.

    The point of this story is that software is everything. Software means the
    interaction of diverse pieces of software.

    That's for reading my story. I have three computers and an Xbox 360. I'm
    thinking of getting a fourth computer because I can't get the mileage I need
    from only three.

    Thanks for sharing that story. I agree software is everything. Have you
    tried asking to send your question up to the next level with calling
    Microsoft support? They may also not be able to help if it the issue is
    based on a 3rd party device and the vendor's software drivers, and
    appropriately it would be a question better posed to the vendor support
    channels. However if they don't respond, there isn't much you can do.

    See if this applies:

    Hi Dan,

    Actually the Vista operating system is a "desktop" operating system, no
    matter what type of hardware it is installed on.

    No, there is no feature to run DNS server services.

    BIND has it's own x86 (32 bit) version to run on Windows XP/2003/2008. I
    don't see why it wouldn't run on x64 Vista, so give it a shot.

    Curious, are you familiar with DNS enough to understand how to configure a
    BIND DNS server, create host records, type of records, general and
    conditional forwarding, 'views,' etc?

    Curious as well, what are your intentions with running an in-house DNS
    server service?

    I'm not totally following you concerning 'tyranny' of ICANN or GoDaddy. As
    for China, you are trying to bypass their restrictions. I believe they
    restrict all outbound traffic, so even if y ou were to use the Roots, it
    probably wouldn't matter.

    Also, I'm not sure how this portion relates to running DNS on Vista. Why not
    just use a server operating system that has DNS built-in?
