Guest FB Posted August 4, 2008 Posted August 4, 2008 I have 180 PCs and i run a Script with NET TIME to check the time sync and for my surprise there is 15 minutes difference (see distribution table below) The Script runs in 3 minutes and i´m puzzled because AD is working fine but there is a Default Domain Policy for block Logins when clocks are not synchronized (5 minutes?!) I´ve followed the article and my PC have a 3 minutes difference between my PC clock and Atomic CLock http://support.microsoft.com/kb/816042 How to configure an authoritative time server in Windows Server 2003 Distribution Table TIME - Ammount 09:27 1 09:28 4 09:29 4 09:30 10 09:31 7 09:32 9 09:33 11 09:34 11 09:35 6 09:36 6 09:37 26 09:38 38 09:39 41 09:40 7 09:44 1
Guest Meinolf Weber Posted August 4, 2008 Posted August 4, 2008 Re: Time Sync - 15 minutes offset Hello FB, The atomic clock is a internet time server or a hardware modul in your server? If it is an internet time server use this way: PDCEmulator: w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update With "peers" you can set the time source, either DNS name (time.windows.com) or an ip address from a reliable time source. Here you can find some of them: http://www.pool.ntp.org/ Client configuration: To configure a client computer for automatic domain time synchronization w32tm /config /syncfromflags:domhier /update After that run: net stop w32time net start w32time Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights. ** Please do NOT email, only reply to Newsgroups ** HELP us help YOU!!! http://www.blakjak.demon.co.uk/mul_crss.htm > I have 180 PCs and i run a Script with NET TIME to check the time sync > and for my surprise there is 15 minutes difference (see distribution > table below) > > The Script runs in 3 minutes and i´m puzzled because AD is working > fine but there is a Default Domain Policy for block Logins when clocks > are not synchronized (5 minutes?!) > > I´ve followed the article and my PC have a 3 minutes difference > between my PC clock and Atomic CLock > > http://support.microsoft.com/kb/816042 How to configure an > authoritative time server in Windows Server 2003 > > Distribution Table > > TIME - Ammount > 09:27 1 > 09:28 4 > 09:29 4 > 09:30 10 > 09:31 7 > 09:32 9 > 09:33 11 > 09:34 11 > 09:35 6 > 09:36 6 > 09:37 26 > 09:38 38 > 09:39 41 > 09:40 7 > 09:44 1
Guest FB Posted August 4, 2008 Posted August 4, 2008 Re: Time Sync - 15 minutes offset The Atomic Clock is provided by a .GOV.BR institution (tips on NTP.BR) I´ll try your suggestion, but why the MS KB Article is not a good procedure?

Guest Meinolf Weber Posted August 4, 2008 Posted August 4, 2008 Re: Time Sync - 15 minutes offset Hello FB, It is more complicated from my point of view to change all the registry keys.
