For Windows systems like this you are definitely in the wrong place
since that's a very specific Microsoft problem. Someone suggested using
a Windows API function to make the query but you would have to wrap that
in some code to use it. It's really not an NTP issue. I all those
systems were running NTP then it's a straightforward query.
