I've recently installed a new 2008 R2 DC in my previously all 2003 domain. I'm planning to transfer over the PDC Emualator role and researching best time management for domain. The article http://support.microsoft.com/kb/816042
recommends to use a 'hardware source' and also reduce the time correction settings. At first, I though they meant the hardware clock in the computer - but further research indicates that they may mean a separate atomic or gps clock placed on the network for just this purpose. I don't find much on the topic of hardware clocks for the network? I realize I can alternately use a NIST external time source on the Internet -- which I somewhat leans towards - but want to do what is 'recommended'. Can someone give me some advice? Also, does any know an article about reducing time connection settings - and it this necessary?
