NTP on Windows Questions

NTP is supposed to be running on our domain controllers.  But I have receiving some error messages from my phone servers that NTP appears unavailable.  From my Windows 7 workstation, how can I test if NTP is up and running on a particular server?  You can see two attempts below and the windows help and documentation does not give a good example.

C:\Users\medfly>w32tm /query /source:10.10.10.139
The following arguments were unexpected:
 /source:10.10.10.139

C:\Users\medfly>w32tm /query /computer:10.10.10.139
The following error occurred: missing parameter

Part II: How can I tell with which ntp server my Win 7 laptop computer is syncing?  

Thanks.

you query the status by issuing the following command to know the status on ur PC

w32tm /query /status

Open in new window


and use the following command to test the NTP server <use your server ip/name instead of 0.pool.ntp.org>

w32tm /stripchart /computer:0.pool.ntp.org /samples:1

Open in new window


Hope this helps
