NTP Synch time imrovement
Hi,
We have in total 6 sites, all of them in different countries, but the two sites in question are in the same time zone.
I have logs of NTP from the main DC (Server) and the client, the client seems to be someitmes falll out of synch, not sure why, and it affects everything when it does, so I just thought i will compare the NTP logs of client server with main DC, from which its getting its time from, there is slight delay in Root Dispersion, but not sure if its critical, can someone see the logs and suggest if the synch can be improved better.

Hello Striker007,
In my case i had an issue with the main DC, it does not sync with NTP server probably which effect the clients, so i ended up by create a batch file and schedule it to run with admin privilege using Window task scheduler.
you can crate batch file with following command;
Net Stop W32Time
w32tm /config /syncfromflags:manual /manualpeerlist:0.au.pool.
W32tm /config /reliable:yes
Net Start W32Time
W32tm /config /update
W32tm /resync
On the Main DC check if you enabled the NTP by checing the following registry entry
[HKEY_LOCAL_MACHINE\SYSTEM
"Enabled"=dword:00000001
On one of your client check the following seeting and interval;
[HKEY_LOCAL_MACHINE\SYSTEM
"Enabled"=dword:00000001
"SpecialPollInterval"="300
and finally if you want to force your client to sync the time at login, you may create a batch file and use group policy to push at login using the following command in your script;
w32tm /config /syncfromflags:DOMHIER
i hope this will help.

only the pdc should get time from an authoritative time source everyone else should get their time from the pdc.. I would have a pdc in each country getting its time from the closest authoritative time source.

there is only one PDC......from where all the other domain controllers are getting there time from....
