(from http://www.meinbergglobal.com/english/sw/ntp.htm)

"The [Meinberg] 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. Please see the NTP Installer
Readme for help on how to use the installer.

If you have any questions or feedback regarding the Meinberg Windows
Installer for NTP, please send your mail to ntp-support at meinberg.de."

The NTP Distribution HTML documentation is archived at
http://doc.ntp.org/.
