NTP Configuration and Track Editing

Verifying NTP Status

1. Click the NTP Status tab. You should see the green line indicating that the service is running correctly.
2. Click the Statistic tab in the NTP Time Server Monitor window. A few minutes later you can view the statistics of the NTP synchronization.
3. To monitor the offset between the server and the client, under Available Logfiles click the browse button and in the folder C:\NTP\ETC\ select the loop statistics file. Typically, one file is generated per day. Click that file in the list to view the time-offset plot (in red). In most cases the offset, that is the difference in the clock time between the computers, is within one millisecond.

The NTP.CONF File

The ntp.conf file is a text file which contains the lines as shown below. You can open the file with the Windows Notepad.

Make sure that the IP address shown in bold is the IP address of the NTP Time Server, that is, your DSI-computer.

# NTP Network Time Protocol
#IMPORTANT: WITH W7 MAKE SURE THE MONITOR RUNS AS ADMIN
# SET THIS IN THE PROPERTIES OF THE SHORTCUT

# Use drift file

# End of generated ntp.conf --- Please edit this to suit your needs

Notes

• When the two computers are in the same network domain, the domain administrator can use his/her existing account. However it is always possible to create a separate account as described above. The account must have the rights to start the NTP Service.
