Appendix E Setting up the NTP Server
(Windows)
This appendix describes how to specify and set of an NTP server for a specific Windows operating system.
This appendix is not needed for Active Directory member servers.
Active Directory member servers automatically synchronize the system clock with the domain controller.
E.1 Overview of NTP Client Settings
This appendix describes procedures for settings synchronizing the system clock with an NTP server for
operating systems consisting of the following:
- Windows Server 2008 R2
- Windows Server 2012
- Windows Server 2012 R2
Remark
In the PRIMEQUEST 2000 series, the system time of a partition is kept in the Home SB. Therefore, if the
Home SB of a partition is replaced during maintenance or switched by the reserved SB function, the
system time of the partition may become incorrect.
The system clock synchronizes with an NTP server once a week in the default configuration of the
Workgroup environment of Windows. Before Windows Server 2008, the system clock is synchronized at
system startup. However, in Windows Server 2008 R2 or later, it is not synchronized.
Use the following procedures to set the system to synchronize with the system clock.
