Setting my PDC Emulator to time sync to external time source

[aja44]

Hi all,

I have a couple of servers and a few hundered computers in my school. I
have a time sync as part of the users logon scripts that sync the time on
their PC to the PDC Emulator FSMO box. All DC's are running Server 2003 with
a couple of 2000 servers running applications. All the servers and PC's show
the same time as my PDC Emulator. But when I go to
http://www.time.gov/timezone.cgi?Eastern/d/-5/java for time I find that I am
3 minutes off. I would like to sync my PDC Emulator DC to an outside time
source. Can some help me out doing this. I found a kb article that has a
series of registry settings but reference peers which I did not understand.

Thanks,

Use this command on your PDC:
w32tm /config /manualpeerlist:<timesource> /syncfromflags:manual
/reliable:yes /update

where <timesource> is the IP address or DNS name of your external
timesource.

and restart the time service with (might not be needed, but just in
case...):
net stop w32time
net start w32time

All other Domain Controllers should sync automatically with the PDC and all
other clients (member servers and workstations (Windows 2000+)) in the
domain, should automatically sync with any Domain Controller - no need for
syncing in the logon script.

To assure normal domain time syncing on other than the PDC, use this
command:
w32tm /config /syncfromflags:domhier /update

and restart the time service with:
net stop w32time
net start w32time


Hope this helps,
