I have a windows server 2003 evironment with two domain controllers in the main office. There are 5 additional remote offices with thier own domain controllers on site, they are joined to the same domain. All remote offices are connected to the main office through always on vpn connection. The PCD is at the main office, I would like to syncronize time with the PDC on all domain controllers throughout the organization, if that is the correct way to do it? Right now the time is off by a few minutes between the different offices, and the main office DC. What I need is help on how to correctly setup the time so it is the same throughout the organization. &nbsp;
