In a windows network enviroment, what could be causing all the PC's clocks to be shifted 10 minutes for example? which clock do they follow? firewall? GC? DC? Even if fixed manually the clock shifts later.

Hi Rubix Computers within an AD domain will synchronise their time with a nearby DC. DCs within a domain sync time with the DC holding the PDCE role. Within a forest, PDCE role holders sync with the forest root PDCE holder. The forest root PDCE holder should be configured to sync with an external time source.

PDCE = PDC Emulator (one of the flexible single master roles) Here's the KB article that describes how to set the synchronisation with either an internal clock or an external source. http://support.microsoft.com/kb/216734/EN-US/ Tony -----Original Message----- From: ActiveDir-owner@xxxxxxxxxxxxxxxxxx [mailto:ActiveDir-owner@xxxxxxxxxxxxxxxxxx] On Behalf Of rubix cube Sent: Tuesday, 23 August 2005 8:35 p.m. To: ActiveDir@xxxxxxxxxxxxxxxxxx Subject: Re: [ActiveDir] PC clock Thank you Tony, PDCE is ?
