Hi Dave,

first thing you should do is uninstall all time sync applications you have tried, this is important as they will interfere with each other. Then restart Windows (note *not* shutdown and reboot) as I know for sure that Dimension4 for one is not fully removed until a restart.

Once the decks are cleared install the Meinberg NTP Client application. In the installer pick a pool near to your location and also take the default of using the SYSTEM account for the service. That should be all you need to do. Use the "Quick NTP Status" tool that you will find on your start menu to check if the NTP client is synchronizing with one of the pool servers. You should see a '*' character in the left most column of one of the server lines after a couple of minutes, that indicates a suitable server has been picked for synchronization.

This is what the Quick NTP Status shows for me:

+mail.classdesig .PPS.            1 u  186  256  377    1.598   -2.114   0.191

Note that I have a local stratum 0 GPS synchronized NTP server so that is what the NTP client has synchronized to as it is by far the most accurate time source I have. The server lines starting with '+' are standby servers that are selected and those with a '-' are rejected as being less accurate due to higher jitter or are time offset outliers.
