Basic information on NTP can be found on our NTP info page.
The Meinberg NTP packages provide a GUI installer for Windows which installs the NTP service and associated executable programs which have been compiled from the original public NTP source code available at the NTP download page at ntp.org.
The GUI installer also contains the corresponding HTML based NTP documentation, plus an OpenSSL DLL required by the NTP service to support symmetric or public key authentication.
Unattended installation is also supported. Please see the NTP Installer README for help on how to use the installer.Actually there a different stable NTP versions provided, plus some additional information:
- NTP for Windows XP and newer, with IPv6 support
- NTP for Windows NT and 2000, IPv4 only
- External Web Links
- NTP Cheat Sheet / Short Reference
- Linux driver for Meinberg plug-in radio clocks
For the Windows operating system there's also an NTP Time Server Monitor program available which allows configuration of the local NTP service and graphical monitoring of the local and remote NTP servers.
If you have any questions or feedback regarding the Meinberg Windows Installer for NTP, please send your mail to email@example.com.
NTP for Windows XP and newer, with IPv6 support
The current stable NTP version can be used with Windows XP and newer, on 32 bit and 64 bit Windows versions. Beside the standard IPv4 network protocol it also supports IPv6. Alternatively there's an older version available which can also be used on Windows 2000 or Windows NT.
Note: The current stable version ntp-4.2.8p4 provides some security patches fixing some vulnerabilities detected in earlier versions of the NTP package. This package contains openSSL DLL v1.0.1p as well, which also contains some security fixes.
It is recommended to upgrade earlier installations to this version.
The version currently provided here with suffix "+mbg" (i.e. 4.2.8p4+mbg) contains a local bug fix for an error which made it into the official 4.2.8p4 version. That bug caused ntpd not to synchronize to the "local clock" source anymore. See NTP bug 2965". Especially users who currently run the NTP package 4.2.8 in combination with the Meinberg driver software for Windows should install this updated version since otherwise the NTP server may always claim to be not synchronized, and thus NTP clients refuse to synchronize to it. The next public release version 4.2.8p5 will also contain this bug fix.

NTP package with IPv6 support for Windows XP and newer
NTP for Windows NT and 2000, IPv4 only
This version of the NTP package is outdated but is still provided since it can also be used on Windows 2000 or even Windows NT. It supports IPv4 only, but not IPv6. For current Windows installations the current stable NTP version should be firstname.lastname@example.org (2.80 MB)
Old stable NTP package for Windows NT/2000 (IPv4 only)

- David Taylor created a detailed step-by-step walkthrough of the installation on his website.
- The official documentation of the NTP Reference Implementation is included in the setup program and will (optionally) be installed together with the binaries. It is also available of the NTP documentation website. Please make sure you select the NTP version that is included in the installer.
NTP Cheat Sheet
NTP Cheat Sheet v1.0 (308 kB)
NTP Short Reference (A4, 2 pages), English language. Contains short lists of the most important NTP configuration parameters, command line options and file formats used by NTP, e.g. for the keyfile or the statistic files that can be generated by ntpd (loopstats, peerstats, clockstats, sysstats).
Linux driver for Meinberg plug-in radio clocks
A Linux driver for Meinberg PC plug-in cards is available on our driver download page. That driver is only required for plug-in radio clocks. Radio clocks which are connected via a serial interface are directly supported by NTP.
