Sync time of W2k8 server to another W2k8 server - non domain controlled

  • 772

I have multiple W2k8 R2 servers and one of them uses an outside source to constantly sync time. I'd like to sync all my other servers to that server. This is a simple workgroup and no domain controller is present.

Anyone knows how to achieve this?

Thanks,

Tom

    I just found an article that describes how to do this.
    You can enable Windows to serve as an NTP server as outlined here: http://www.windowsitpro.com/article/time-synchronization/how-can-i-enable-a-network-time-protocol-ntp-server-.aspx

  2. From Microsoft:

    The solution to keeping all workstations' time synchronized with a particular server can be solved by either running a logon script for each workstation or by having each workstation run a batch file on their own after logging on to the network. For example, assume you have a server named TIMESRV that has a reliable system clock. An example batch file that would run either from the workstation, or get called from or be part of a logon script, would look like this: NET TIME \TIMESRV /SET /YES

  3. All of this that you guys wrote won't work on the Windows 7 / Windows 2008 Platform.

    I have many Windows XP machines, and I time sync them using a GPS receiver. The machines get connected to that receiver using SymmTime, that's a software that won't work on Windows 7 / Windows 2008.

    So what I did for the Windows 7 machine was just update it using time.microsoft.com (or another NTP server, it won't matter) but increasing the frequency of the update from once a week (Windows default) to once a day. I can visually notice that the Windows 7 machine has the same times as the other Windows XP machines that are time-synced using the GPS receiver.

    Follow this guide to do the once-a-day time syncing with an NTP server on Windows 7. http://www.pretentiousname.com/timesync/index.html

  4. Configure one server to be an NTP server (it will need to be a client of >=2 NTP sources), and configure the other to be a client of the first. TechNet details the registry values.
