    But you can... See your text below.

    OK. So you specified two possible time sources for testing. Good.

    So you observe, that you don't get time corrections from your XP.
    Non conclusive yet.

    So here you observe, that using another time source you _do_ get
    time corrected on your Linux box. Good.
    Conclusion 1: NTP synch _works_ for your Linux box _with_ _a_
    _working_ _time_ _server_.

    Here you repeat your first test, but this time with an
    added knowledge of NTP sync working with another source.
    Non conclusive yet, but your following assertions:

    > Either XP isn't set up to deal with NTP or the request
    > never makes it to XP.

    are valid.

    > The question remains, why doesn't this work?

    1) check networking:
     - can you ping your XP box from your Linux box?
     - other way round as well?
     - using names as well as IP numbers?
     - can you transfer some data between both boxes?
       (Samba, www, etc.?)

    Only after you positively verified each step from '1'
    do:

    2) Is NTP _server_ installed and configured on XP?
    (how to check this one is up to you. I don't do windows).

    HTH.

    PS: Reading this veeery lengthy thread reminded me of an
    old joke. Disclaimer: absolutely no offence meant.

    Holmes and Watson went for a night out camping.
    They went to sleep in their tent.
    In the middle of the night Holmes silently wakes up Watson
    and asks him to look up and describe what he sees.
    Watson looks up and begins to describe how beautiful the
    starlit night sky is, and how many stars there are and how
    romantic and scientific the wiew is...
    Holmes impatiently interrupts him saying "you fool! don't you
    _see_ that someone stole our tent?" :-)
