root@linux:/# ntpdate -q 44.60.44.1
server 44.60.44.1, stratum 0, offset 0.000000, delay 0.00000
31 Jan 01:22:52 ntpdate[29207]: no server suitable for synchronization found
root@linux:/#
On Windows 8 desktop PC, by means of quite old program D4.exe
(Dimenison 4) got nice sychronization with the following setup:
