This has been discussed here so many times It's rarely worth repeating.
Windows (w32time) is a sntp client at best, steps the clock and does not
discipline it. The version introduced with Windows 2003 SP1 we know a
lot less about. However, we do know that the publicly available server
that Microsoft makes available (something like
time.windows.microsoft.com, I forget the exact address) is such a bad
provider of NTP packets that Dave has found it useful as a source of
poor-quality NTP packets to debug his algorithms.

Note that the version available for W2003 is not available for XP or
other O/S versions (we don't know about Windows Vista). If all you need
is approximate time then stay with w32time. We don't need more clients
asking for time unnecessarily.

It's your choice.
