You can start with below How to configure an authoritative time server in Windows Server http://support.microsoft.com/kb/816042 First and foremost, Configure your PDC Emulator to point to an external time source. Identify the PDC emulator http://technet.microsoft.com/en-us/library/cc782961(WS.10).aspx For all other Domain Controllers, set the W32Time service to use its settings as follows: Stop the w32time service Run w32tm /unregister and w32tm /register at the command prompt Start the w32time service If you are running DC's on virtual environment then, please have look at following blog post Time Synchronization in Hyper-V http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/11/19/time-synchronization-in-hyper-v.aspx HTH ~Santosh

Hello, By default, all domain servers / DCs sync time with the PDC Emulator of their domain if they are using NT5DS for time sync: http://support.microsoft.com/kb/223184 Please check that port 123 is not blocked. I would recommend making the PDC emulator sync time with a public NTP Server: http://www.ehow.com/how_5981545_configure-windows-ntp-client.html This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
