NTP
(ver 4.2.4p8)
Freeware


NTP is an accurate NTP Server developed at http://www.ntp.org. 
In most cases a "Daytime" Server is a better choice to operate.
 
The NTP project mainly produces source code releases of NTP.  
At the moment there is no official Windows binary distribution 
available from them. Because a lot of their customers do not 
have the time or resources to build their own binary version 
of NTP, Meinberg decided to offer a pre-compiled, easy-to-install 
software package including an actual version of NTP and all 
necessary third party add-ons (e.g. OpenSSL libraries).

This NTP package contains a GUI installer for Windows 
which installs executable programs which have been compiled 
from the original NTP sources available at the NTP download 
page at ntp.org. The GUI installer also contains the 
corresponding HTML based NTP documentation, plus a current 
OpenSSL DLL required by NTP to support authentication. 
Unattended installation is also supported.  This version of 
NTP only runs on Windows NT and its successors (Win2k, etc.).  

In order to use this installer, you need Administrator rights. 
This is only necessary during installation, as the NTP 
software itself runs fine without admin rights, as long as the 
SetSystemTime privilege has been assigned to the account used 
for running the service. We strongly recommend to not run 
NTP (or any other system service, if possible) using the local 
system account, or any other account with full administrator 
rights. If you want, the installer will create a restricted 
account running the NTP service.



NOTE: This is the last Win2k version, and it will only support 
IPv4 (no IPv6 support).
