Just a few points:

- the presence of the "*" in the output of ntpq -pn indicates sync, so 
I'm unsure that the problem is.

- I recommend installing outside the \Program Files\ directory, and I'm 
not sure you've done that.

- Using a single server is bad practice.  Use the pool directive instead 
and don't try and specify the min/max poll:

   pool hk.pool.ntp.org iburst

NTP will adjust the polling as it needs to, and will try and get a 
number of servers rather than just one.  You should use a driftfile line 
in your ntp.conf file as well.

   driftfile  C:\Tools\NTP\etc\ntp.drift

if you have installed to C:\Tools\NTP as I recommend:


You actually seem to have made things more complex for yourself than a 
default install might have done, but perhaps that is the result of 

(There are some issues installing on Windows Server, of which I have no 
current experience).
