RE: [ActiveDir] time sync..

Hi Manjeet   Domain members sync their time with a local DC.  DCs sync their time with the PDCE.  The PDCEs for each domain sync with the root domain PDCE.  The recommendation is for the root PDCE to sync with an internal hardware clock, but an exerternal time source would also do the trick.  This is true for both mixed and native mode.    Time should be ok if the PDCE is out for a short period of time, because the time on the machines that sync with it are not likely to go out of sync quickly.    If you plan to take the the PDCE out for any length of time (e.g. for major maintenance) then consider transferring the PDCE role to another DC in advance.    Tony From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Manjeet Singh Sent: Wednesday, 14 December 2005 8:11 a.m. To: ActiveDir@mail.activedir.org Subject: [ActiveDir] time sync..   In an windows 2003 AD environment-   In terms of time sync, what’s the effect on client when the server having PDC emulator role is down?   One of my third party clients (outside the AD environment) is unable to sync the time with the AD ntp server when PDC emulator server was down.   What are the actual roles of a PDC emulator in syncing the time?   Is this functionally is different in mixed and native mode?     Thanks, Manjeet
