Hi all,
Currently, I am working with meinberg ntp and I can't sync with ntp server. I
have made rules that allow UDP port 123, turned off w32time and change to some
popular ntp server but there is no luck.
I have followed this FAQ:
http://www.meinbergglobal.com/english/info/ntp-w32time.htm
I'm using windows web server 2008 R2, Meinberg NTP version is
http://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable (the spider man one)
this is the output from ntpq -pn
C:\Windows\system32>ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
*218.189.210.3 137.189.4.10 2 u - 512 17 30.634 -46.455 23.503
this is the output from ntpq -crv
C:\Windows\system32>ntpq -crv
associd=0 status=0615 leap_none, sync_ntp, 1 event, clock_sync,

clock=d7676117.210e61c3 Wed, Jul 9 2014 13:35:03.129, peer=7365, tc=9,
mintc=3, offset=-46.455, frequency=-65.949, sys_jitter=0.000,
clk_jitter=31.032, clk_wander=0.024
And this is my ntp.conf file:
server 0.hk.pool.ntp.org minpoll 9 maxpoll 11 iburst
I am looking forward for your response.
Just a few points:
- the presence of the "*" in the output of ntpq -pn indicates sync, so
I'm unsure that the problem is.
- I recommend installing outside the \Program Files\ directory, and I'm
not sure you've done that.
- Using a single server is bad practice. Use the pool directive instead
and don't try and specify the min/max poll:
pool hk.pool.ntp.org iburst
NTP will adjust the polling as it needs to, and will try and get a
number of servers rather than just one. You should use a driftfile line
in your ntp.conf file as well.
driftfile C:\Tools\NTP\etc\ntp.drift
if you have installed to C:\Tools\NTP as I recommend:
http://www.satsignal.eu/ntp/setup.html
You actually seem to have made things more complex for yourself than a
default install might have done, but perhaps that is the result of
experimenting!
(There are some issues installing on Windows Server, of which I have no
current experience).
