How to configure an authoritative time server in Windows Server 2003 [http://support.microsoft.com/kb/816042]

Configuring the Windows Time Service [http://www.windowsnetworking.com/articles_tutorials/Configuring-Windows-Time-Service.html]

I have several PDC's located in each capital city and users authenticate to these local PDC's. Onse state in particular still running Windows 2000 Server (PDC) has a PC that regularly goes out of synch (time) with the PDC so i must log into the machine remotely and force the update before the user can log back onto his machine. <br />
<br />
I understand that the time synchronisation is advertised by the PDC but what about the prospect of setting up a central NTP server in the Head Office and configuring each machine to use this central NTP server to keep all the times up to date?<br />
<br />
Will this cause issues with the workstations authenticating on the PDCs?
