JSI Tip 8497. AuthSync.bat script makes your Windows Server 2003 PDC emulator the authoritative time server for your domain.

I have scripted AuthSync.bat to configure your Windows Server 2003 PDC emulator as the authoritative time server for your domain.

The syntax for using AuthSync.bat is:

AuthSync Seconds withIP1 [WithIP2 WithIPn] [\PDC]

Where:

Seconds is the number of seconds between each external time source synchronization event.withIPx is the IP address of an external time source.\PDC   is the computer name of your Windows Server 2003 PDC emulator, if you run the script remotely.

Example:

AuthSync 900 192.5.41.41 192.5.41.209 \JSI001

will cause my Windows Server 2003 PDC emulator, \JSI001, to synchronize its' clock, using SNTP (Simple Network Time Protocol), with the the U.S. Naval Observatory, tock.usno.navy.mil (192.5.41.41) or ntp2.usno.navy.mil (192.5.41.209), every 15 minutes (900 seconds).

AuthSync.bat contains:
