Thread: Inconsistent time server (NTP) access

    Default Inconsistent time server (NTP) access

    ZA 80298000 (Free)
    Win XP Home SP3

    Using internet time servers to keep my laptop's time in sync using the regular Windows "Date & Time Properties" dialogue from the system tray

    If I use time.windows.com or time.nist.gov all is OK

    If I use pool.ntp.org (or any of their hosts) ZA blocks access, unless I add the server to the Trusted zone.

    I don't understand the inconsistency as surely all time servers are using port 123.

    I am unclear about the security implications of having an internet host in my Trusted zone.

    I can supply packet dumps/logfiles/whatever on request, but I don't know what will be useful to help resolve this.

    thanks in advance for any assistance

    Hi!its related to the delay connected to theserver (or your connection), ifthe answer is too late then the connection is dropped. Not a ZA issue but a server issue. Choose one near you.For me "time.windows" is a no go! I have time-a.nist.gov and everything works perfectly.Cheers,Fax

    thanks for such a quick reply

    I'm in the UK and have tried uk.pool.ntp.org which is physically the closest server pool (withing 200 miles or so).
    nist.gov is several thousand miles away!

    (I realise there may be other lags introduced)

    I'm still wondering about the implications of using Trusted zone for these servers

    I'm cool with the timing issue -- it makes enough sense to me as an answer as to why there might be a
    a problem
    What I'm struggling with is
    ... I'm seeking information (&quot;What are the implications of placing these time servers in the Trusted zone?&quot and the response I'm getting is &quot;Why do you want to do that?&quot;.
    From where I'm sitting, an answer to the latter question is not a necessary condition for an answer to the former; and information has already been given, that is,
    &quot;I can't use these servers unless they are in the Trusted zone&quot;.
    If the extra information you need is an answer the question &quot;Why do you
    want to use those particular servers&quot; , then that's
    straightforward: Because that is what I want to do.

    Implications? That whatever comes from that server is not filtered by ZAIs that good? Bad? Depends on thesecurity of the server considered.It makes little sense to me to be forced to add a trusted server if you can choose a working untrusted server especially if we are talking about syncro of time and date ...
