Synchronize an internal time server with an external time source

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To synchronize an internal time server with an external time source

  1. Open Command Prompt.

  2. Type the following, where PeerList is a comma-separated list of Domain Name System (DNS) names or Internet protocol (IP) addresses of the desired time sources:

    **w32tm /config /syncfromflags:manual /manualpeerlist:**PeerList

  3. Type:

    w32tm /config /update

Notes

  • To open a command prompt, click Start, point to All programs, point to Accessories, and then click Command prompt.

  • The most common use of this procedure is to synchronize the internal network's authoritative time source with a very precise external time source. However, this procedure can be run on any computer running Windows XP or a member of the Windows Server 2003 family.

  • If the computer cannot reach the servers, the procedure fails and an entry is written to the Event Log.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
