Hi:
I have had excellent results using
http://www.meinberg.de/download/ntp/windows/ntp-4.2....@lennon-o-lpv-win32-setup.exe
on a windows XP platform, but on windows 7 I never get a good sync.
(The NTP server is a high quality statum 2 time server which provides
excellent time to Fedora/Linux clients.) I was wondering if anyone
has any experience w/ windows 7 with Meinberg (or any other NTP)
software.

Gautam, I have also found that Windows Vista and Windows-7 are not such
good time keepers as Windows XP. Windows-7 32-bit will work as a
stratum-1 server with a GPS/PPS serial reference:

being typically within 50 microseconds, and I have other systems,
including a Windows-7 64-bit system synced over the LAN:
http://www.satsignal.eu/mrtg/alta-ntp-b.html
which is within a couple of milliseconds (using 32s poll,
minpoll=maxpoll=5). The problem is that the rather excellent
interpolation scheme developed for Windows cannot be used with the later
versions from Vista onwards which have a higher clock interrupt rate.
You can see the performance of all my systems here:

If timekeeping on Windows is critical, consider getting a PPS signal sent
round to the PCs which matter. You need pay no more that US $35 for a PPS

Be aware that later versions of NTP are available.
Cheers,
David
