Windows 7 ntp server setup

It provides a facility to reject timestamps that are too far away from the hosts system time. Microsoft recommends a setting of 1 hour or 30 minutes Restart the windows time service. When Windows for Workgroups is deployed, you have to manually configure time synchronization settings.

You need to specify the time server that the Windows Time Service is to use as a reference clock. Alternatively, you can utilize the date and time properties applet from the control panel. If so, it will synchronize to the domain controller.

In this instance, you will need to configure the domain controller to synchronize with an NTP server. The ntpd daemon is configured from a configuration file ntp. Note: Remember that it is not recommended to configure smeared and non-smeared NTP servers. You should avoid excessive use of public NTP servers. Only query servers at reasonable intervals. This may vary from once a day to a few times an hour, depending on your system requirements.

NTP clients should never be configured to request time from a NTP server more frequently than once every four seconds. Clients that exceed this rate may be flagged as attempting a denial of service DoS attack and may be refused service. It is generally accepted good practice to choose a relatively local time reference. Using local time references will reduce network latency and round-trip delays and provide a more robust time service.

Public time servers are often maintained by volunteers. They provide no guarantee of availability or accuracy. You use them at your own risk. Also, many NTP authentication and security mechanisms cannot be used with public time servers, which may leave your systems open to abuse.

If your organisation requires an accurate and reliable source of time, you should seriously consider installing a local time reference. Important: TimeTools cannot be held responsible for the availability or operation of the public NTP servers listed on this page.

Maintaining accurate time on your server is critical largely because many services and IT applications rely on accurate time settings to function as expected. These include logging services, monitoring and auditing applications, and database replication to mention a few. Time skew in servers, and any client systems for that matter, is undesirable and usually causes conflict in time-critical applications.

Thanks, Alan. Friday, February 25, PM. Hi Yshwartzou, According to my test, you may need to add two steps in NTP server end, and so no change is needed in client. Wednesday, March 2, AM.
