How to Configure an Authoritative Time Server in Windows

All Microsoft Windows Servers 2000 and onward have time synchronization utility built into the operating system, which can be set by following some simple steps. In all modern internet networking systems, configuring authoritative time server is essential. It can coordinate all systems in a network through the internet in different countries showing the same time, which helps in authentication of communication time as and when it happens. The system called Windows Time Services once configured works as an NTP server, synchronizing time to unified time. Carefully follow each step and this will make your job a lot easier.

    External Time Sources

    Almost all operating systems manufacturers recommend that external time sources be used as a general standard as the internet sources cannot be authenticated. This is the main purpose of the Windows Time Service, that to coordinate the time in all systems in a network globally. The service dictates the same time to all systems and thus authenticate timing of all communication as and when it happens. The time is essential to emails and all other applications that store or process information.

    This again will pop up another pane. You should type 'AnnounceFlags' and the click on the 'Modify' button. The 'AnnounceFlags' is registry that shows whether the server you are trying to access is time trusted.
