Xenta Servers and Time Synchronization

Xenta Servers and Time Synchronization

Issue

The time in TAC Xenta Server should be the same as the time on the TAC Vista Server PC.

When Xenta Servers connect to the TAC Vista Server, they should synchronize their time with the Vista PC.

Product Line

TAC Vista

Environment

  • Xenta Servers
  • Xenta 511, 527, 701, 711, 721, 731, 913
  • NTP Server
  • Vista Server

Cause

There are different scenarios.

  1. Vista Server PC has no internet connection
  2. Vista Server PC has internet connection

Resolution

Corresponding to the causes above:

  1. Set the Xenta Server to synchronize with the Vista Server PC. You do that by adding this AuthoritativeNTPserver.zip reg file to the registry on the TAC Vista Server PC, and enter the IP address of the PC into the Xenta Server as described in Setting NTP in Xenta Server.pdf.
  2. Set the Xenta Server and the Vista Server PC to synchronize with a NTP server on the internet. Find servers here: http://support.ntp.org/bin/view/Servers/NTPPoolServers
    Area HostName
    Worldwide pool.ntp.org
    Asia asia.pool.ntp.org
    Europe europe.pool.ntp.org
    North America north-america.pool.ntp.org
    Oceania oceania.pool.ntp.org
    South America south-america.pool.ntp.org

In general, make sure that firewall is not an issue. NTP uses port UDP 123
