    After adding a W2k3 box tou our NT4 domain, leaving the old NT4 seerver as a
    BDC I can no longer get access to any machine via VNC.

    ANy ideas why this might be happening?

    I assume there is some security setting somewhere that is blocking this but
    I haven't found it yet.

    Cheers,

    Ian

    The most LIKELY reason is some routing problem.

    Do other things work, like tracert and ping?

    If so (they work) then the most likely reason is some
    filtering like turning on the "ICF" firewall (see connection
    or RRAS settings for the Interface.)

    Herb,

    As we say round here, the issue was classed as "PEBCAK", Problem Exists
    Between Chair And Keyboard.

    Attempting to access the boxes via hostname through our VPN results in my
    error message but accessing the boxes via IP Address works.

    Thanks for jogging my memory, it's been a while since I had to work remotely
    and I must be getting old and frail-brained!

    Cheers,

    Ian

    We all get confused some of the time -- one of the reason
    I can usually help is that I have made most of the mistakes
    you CAN make. <grin>

  5. Hello Ian,

    Thank you for your post, and also thanks to Herb for the inputs.

    If we can use IP address to access the remote computers successfully, it
    indicates that it is a name resolution issue. We should be able to resolve
    the problem by checking the VPN server settings to ensure that the VPN
    clients get the correct DNS and WINS server.

    We can open the VPN server's properties in the RRAS snap-in and check the
    settings on the "IP" tab to ensure that the VPN clients will get the
    correct DNS and WINS configurations.

    Thanks!
