F.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 2003/Windows Server 2003 R2
The setup steps do not distinguish between Windows Server 2003 and Windows Server 2003 R2. Windows
Server 2003 and Windows Server 2003 R2 are both called "Windows Server 2003" in this manual.
- Windows Server 2008
- Windows Server 2008 R2
- Windows Server 2012
Remarks
This appendix is not needed for Active Directory member servers. Active Directory member servers automatically
synchronize the system clock with the domain controller.
In the PRIMEQUEST 1000 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.
