    VNC Server

    I've been trying to run VNC server on Vista beta 2 without success. I can
    control an XP PC using VNC viewer from Vista but not the other way round. Any
    suggestions?

    I had VNC running XP > Vista on a network by turning off UAC and the
    Windows Firewall and also disabling Windows Defender which does not
    like VNC much and still seemingly caused problems even though I told
    it to allow VNC.

    I used Ultra VNC 1.0.1

    http://ultravnc.sourceforge.net/

    It worked fine but then for some reason slowed to a crawl, I had been
    fiddling with Vista a lot so I am not sure exactly what the problem
    was. I have re-installed Vista for the nth time this week but not put
    VNC back in yet so I cannot help you further at the moment.

    We have tested VNC version 4.2.5 on Vista #5384. Client runs fine, but
    server fails to start. Only VNC error message is license key: digest
    mismatch. All Vista security is turned off including the firewall.
    Interestingly, the Vista firewall lists VNC as an exception; that is,
    the check option is port use is permitted even if the firewall is
    active. Vista user is Administrator.

    I'm trying to run VNC Server 4 on Vista build 5384.

    When I try to run Configure VNC Server, I get a (Vista?) error message
    saying “You do not have sufficient access rights to run the VNC Configuration
    applet” - this does not make sense as I'm signed on as an administrator.

    I don't like the idea of switching off Windows Firewall, Defender and UAC as
    this seems a little drastic.

    Any other suggestions appreciated.

    Are you logged on as the "real Administrator" not just a user with
    Administrator privileges ? I haven't had any problems with access
    rights, but VNC Server still doesn't work.
    We use a hardware firewall, Firefox, and Thunderbird. There is no
    Firefox support for ActiveX and we disable Java and images. We also
    don't open attachments except under exceptional circumstances. This
    provides a fairly good level of Internet security.

    Robbie what exactly is happening with your server, just re-installed
    it on the new public beta version after a clean re-install and it
    won't run properly now. I had it running fine on a previous beta
    installation.

    Running as admin, all security off, UAC disabled and the security
    centre dlls disabled / service off, defender disabled.Can connect via
    XP or Linux clients but ridiculously slow.

    Re: VNC Server

    Hi Jonah,

    The only VNC server start-up message is License key: Digest Mismatch.
    There are no other error messages, but the server never starts. A check
    of the Internet shows that no one has VNC Server running successfully on
    Vista beta 2.

    I don't know what you mean by "real Administrator". I only have one user
    account on Vista, which is the one created when I first installed Vista, and
    the account is obviously has administrator privelages.

    This is discussed in detail in another thread. Unlike UNIX/Linux, a user
    with Administrator privileges is not the same as the Administrator. For
    example, changing a directory from read only to read/write is possible
    as a user/administrator, but under many circumstances the directory
    automatically reverts to read only. Administrator can write into a read
    only directory, but user/administrator cannot. There is more detail
    involved and this is only one example.
    Microsoft designed Vista so that you cannot normally logon as
    Administrator. There is a registry change that makes this logon
    possible. The steps, as described by Colin in this forum, are as follows:

    Quote
    1) Click the Start orb and click on Run (or press the Windows key + R)
    2) Type in regedit and press OK. If it asks you to open this via UAP, then
    click Allow.
    3) In the Registry Editor, navigate to
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.
    4) In the right hand pane, right click the mouse and select New then Key.
    A new folder should appear in the left hand pane.
    5) Name this new key SpecialAccounts and press Enter.
    6) Right click the mouse on the new SpecialAccounts key in the left hand
    pane, select New then Key again to make a "sub-key".
    7) Name this new key UserList and then press Enter. In this new UserList
    key, right click in the right hand pane and select New then DWORD (32-bit)
    and name this Administrator then press Enter.
    8) Double click on the new DWORD you just made, and set the value to 1
    then
    press OK.

    Hey Robbie, I had it going fine on the version before this public beta
    - 5384.4, honest I did, it worked fine then failed but I got no error
    messages on install and I can't remember exactly why it failed I
    thought it was something I did while poking about elsewhere. I was not
    too bothered as I wanted to reload different hardware and re-install
    anyway so I never bothered investigating.

    I have just got the public beta installed as an upgrade on a test
    machine cos I have been deliberately upgrading / restoring various PCs
    pre-installed Dells, HP etc and custom builds to see what happens
    (wasn't pretty mostly execpt for the Dell surprisingly) I will try VNC
    again tomorrow and take careful notes of exactly what I do, assuming I
    can get it to run again. I am using the original test box hardware now
    which is well specced but its an XP upgrade not a clean install this
    time so this may take a couple of days if I have to do a clean install
    as before, but I will get back to you.

    I did not realise VNC wasn't supposed to work, I did have to do some
    serious tweaking though as I recall, it was a few weeks ago now. If I
    had known it was an issue I would have done a few screen shots on the
    Vista Server and XP / Linux Clients.

    Re: VNC Server

    Hi Jonah,

    I will look forward to hearing from you. I did try working with the
    ports and being careful that the Microsoft firewall and other security
    features were disabled. I also tried Ultra VNC and Radmin neither of
    which worked on #5384.

    Surprise, surprise.
    Real VNC 4.2.5.0 works on Vista #5384 if you go to Administrative Tools,
    Services, VNC Server and start the server from this Window. It will not
    start properly by executing WinVNC4.

    Hi Robbie

    Got it working on the Public Beta.

    Ultra VNC 1.0.1 from
    http://ultravnc.sourceforge.net/

    Via Netgear D834G Router on local only (ie VNC is not set up as a
    server via port forwarding)

    Vista is base install with only Trend AV installed, UAC disabled,
    Firewall Disabled. Ensure local file sharing works correctly XP <>
    Vista R/W

    Set TCP/IP on Vista to fixed Local IP, don't allow automatic.

    DL VNC 1.0.1 and install in an Admin account via "RunA$"
    Administrator. When first run Defender will scream blue murder so go
    through the options and set to "always Allow", only other set up to do
    is to replace login password with one of your choice eveything else is
    left as default.

    Screenshot of Server setup here.
    http://www.gsyminimoto.org/misc/Vist...Properties.jpg

    Then use the corresponding Ultra VNC client in XP to connect to the
    vista machine via the fixed address / port 5900

    Screenshot
    http://www.gsyminimoto.org/misc/XP%2...C%20client.jpg

    Works fine at the moment, I will take note of when it breaks. BTW its
    best to switch Vista to classic theme for speed although it does work
    with a Vista theme its slow but that could be my network connections
    which are a little convoluted.

    Addition to previous post I forgot to mention when putting VNC server
    on the Vista box install the server only (top option box) uncheck
    everything else.

    Hi Jonah,

    Thank you very much for the follow-up about Ultra VNC. I will give it a try.
    Did you see that "Real VNC" is now working ?
    One step I didn't mention is that it is probably necessary to execute
    WinVNC4 before turning the VNC Server on via "Services". As mentioned,
    WinVNC4 will fail, but the step may be necessary to establish the entry
    in "Services"
