Setting Up Time Server on 2008 R3

In order to get Windows to SYNC to an external time server, here is what we do.

Create a BATCH file on the server that has the following lines in it:

REM W32 TIME SETTINGS
w32tm /config /manualpeerlist:time-a.nist.gov,0×8, /syncfromflags:manual /update
REM END OF CODE

Then save it as "SetTheTime.bat" and create a scheduled task that runs that batch file once a day.
