[Samba] Time synchronization issue (solved)

[L.P.H. van Belle]

Ok, good it works now.. 
 
Yes, clients should be synced with the DC.. 
i can only think of 3 reasons why it didnt work or stopped working. 
 
1) If the pc time gets out of sync (+5min)  for some reason, then the client wil try 8 more times and then it marks the source as unusable.. 
    ( if a pc is never rebooted, this can happen also ) 
 
2) u used w32time to set time, and if you run than from within a login script, i wil fail, users dont have rights to set time. 
    this can be set by policy that users are allowed to sync time.. 
 
3) other which i dont now..  ;-) 
    changed time server, winter/summertime change which went wrong..

Hello Louis, 

I have applied patch from kb314054 to set NTP server on the client computer. It works now.


BUT normally, shouldn't clients synchronise with DC by default ? Why doesn't it work ?

Hai, i had this also ..

First set the xp machines within 5 min time difference compaired to the server,
then time should be in sync because time is passed by AD.
If you already had 8 failures of time sync then the sources is excluded..

please read : https://support.microsoft.com/en-us/kb/314054 for more info.

Greetz,

Louis
