How set in Windows Server 2008 r2 interval to sync time with the PDC emulator?

  • 772

In a Windows 2003 domain, I have 7 members servers that are Windows Server 2008 R2. I need to make it so that they sync time with the PDC emulator at least every 15 minutes or less if possible. Is this possible?

w32time windows-server-2008-r2

    You can do this one of two ways:

    Registry & 0x1 flag

    As detailed here, if you set the 0x1 flag using w32tm, you can change SpecialPollInterval located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient to however many seconds you want. For 15 minutes, it would be 900 seconds.

    Scheduled Task

    Alternatively, you can create a scheduled task that runs w32tm /resync every 15 minutes on the target computers. I strongly recommend this over the other option. It's much less complex and can easily be applied via GPO using the Scheduled Tasks Group Policy Preferences item.
