yes, Ntpd is running on the same server that Samba is running which is ,I forgot to add "mssntp" on restrict parameter in ntp.conf, after that some client machines synced time with the server but not all of them , i can sync time manually on any windows machine using command "net time \\ntpserver /set /yes" but the w32tm command has no effect. Sorry for my late response, i'm struggling here to make this thing works, anyway thanks for the help. ----- Original Message ----- From: lingpanda101 at gmail.com To: "Dante F. B.

Hai,
Check a few things.
In ntp.conf
Rule 1 : DONT USE POOL NTP SERVERS !
Rule 2 : Use a stratum 1 ntp server close to you.
Look up here :
http://support.ntp.org/bin/view/Servers/StratumOneTimeServers
Now point all your DC's to the selected ntp server(s)
Add/change these lines to ntp.conf
restrict -4 default kod notrap nomodify nopeer noquery mssntp
restrict -6 default kod notrap nomodify nopeer noquery mssntp
and check if this is set in ntp.conf
ntpsigndsocket /var/lib/samba/ntp_signd
if you not using ipv6 for example, add these to ntp.conf
interface listen lo
interface listen eth0
interface ignore wildcard
interface ignore ipv6
Make sure in smb.conf is :
time server = yes
now restart ntp/samba or the whole server.
Reboot the pc.
Check time again.
If you pc time is off more then 5 min a manualy adjustment often is needed.
'w32tm /config /update /manualpeerlist:IP-of-your-DC-with-ntp-running'
Should not be needed.
Time is synced over the AD.
A good example can be found here.
