Using NTP 4.2.8p10 instead of the Windows Time Service doesn't make
sense on most Windows machines, but it does make sense in some

be configured to behave as desired.

That is not an opinion with which everyone would agree.

For me, the reference NTP should be the default installation on Windows
PCs for its flexibility, configuration, management and performance
capabilities, and its compatibility with other OSes making management
across multi-platform installations easier.

Only where NTP is an unacceptable option would I accept Windows Time
Service - it's a much poorer and less flexible alternative.


Note that all recent/current versions of the Windows Time Service are
in fact SNTP/NTP implementations, with quality of implementation
improving in newer versions.

Old (now unsupported) versions of the Windows Time Service violated the
SNTP/NTP specification in ways that required special workarounds in
standard NTP servers.  Even older implementations that didn't even
include a service named "windows time service" used simplistic time
queries over the SMB protocol.

Besides being included with the OS, the "windows time service"
typically defaults to imposing a much lower load on the selected time
source, by using much longer poll intervals.  In "Active Directory"
(Windows 2000 and later) setups, there is also a dead simple automatic
configuration, where each machine simply syncs against it's nearest
"upstream" in the authentication/management hierarchy, limiting
practical management work to machines that have no such "upstream",
such as the 2 to 4 machines at the top of the tree.  And of cause
machines needing more precise time than needed by the basic Windows
functions.



Enjoy
