Hi!
Some days ago I tried Meinberg NTP on my Server2008R2.
After some security issues (administrator rights required, compatibility) NTP worked as service..
But after a while I recognized, that Windows-Time was not set when polled.
Polling was at 1024 (17min) and time was set only in 90-120min intervals.
Here a short copy of the system log:

Die Systemzeit wurde von 2014-06-01T17:49:58.337959600Z auf 2014-06-01T17:49:58.154000000Z geändert.
Die Systemzeit wurde von 2014-06-01T15:44:35.212169700Z auf 2014-06-01T15:44:35.050000000Z geändert.
Die Systemzeit wurde von 2014-06-01T14:14:29.175169100Z auf 2014-06-01T14:14:28.996000000Z geändert.
Die Systemzeit wurde von 2014-06-01T12:44:13.086669300Z auf 2014-06-01T12:44:12.944000000Z geändert.

Another issue was, that ntpd.exe (service) refused working after some days. I get mail notification about. 
After restarting the service polling also started again.
I use my own stratum-1-time-servers (GPS) in the LAN which were available all the time. In this special case none of the mentioned time-servers (LAN , at.pool) respond. Other machines could sync the time very well. 
The time-servers are built with an evaluation board of a 32-bit ARM Cortex-M4F micro-controller and a GPS-Module with external outdoor antenna.

The delay (90-120min !!) while setting the windows-time also occcured on a Win8.1 machine.

I'm really confused .....

Hartmut
