    I am only addressing the question "Is this a supported config?"
    to which I believe the answer is no. SP4 for NT was released
    with some back-port of what was envisioned would be needed
    for AD inter-op but this was back when it was still call Windows
    NT5 instead of Windows 2000.
    Have you tried with the NT domain at SP 6a?

    You issues of course may be due to other reasons, but I do
    believe it is true to say that trust of W2k3 with NT4 at SP 4
    is not a supported config.
