hi gurus, is there a way to sync time for all DC's in an AD environment?
let's say I have 5 DC's, can I change the time on any of the DC and then replicate the time change for all the DC? how do i do this?
thank you.
Every second counts..make use of it.

AD has a built-in domain-hierarchy based time synchronisation mechanism. This is the default mechanism, but can be changed.

You will need to configure the DC that holds the PDC Emulator FSMO role to obtain time from an authoritative source (either external or hardware-based).

Hello,
Agree with Tony.
By default, DCs automatically sync time with the PDC Emulator. If you want to manually sync time on a DC, run the command w32tm –resync.
For more about w32tm, refer to

Thanks

Cguan,
I agree with others,
DC's follow their own time hierarchy (UTC Timing convetnions), Time displayed on computers are only for human's. Even If you change the time on one of the DC it does not effect the time hierarchy.
You need to understand the follow.
External Time source---->PDC Emulator holding DC------>Other Domain controllers--------->All client computers.
or
Internal Time source---->PDC Emulator holding DC------>Other Domain controllers--------->All client computers.Refer below flowchart,
Please refer below techwiki article
Hope this information helps

Hello,
there is not tool required, it is built in complete and you just have to use, if possible, an external time source for the PDEmulator FSMO DC, that's it.

Thank you gurus, for your valuable inputs.
How do I check which Time source the PDC emulator is pointing to?

on the PDC emulator go to HKEY_Local_Machine--->System---->CurrentCotnrolSet----->Services---->w32time---->parameters----->check reg NTPservers
You willl get the Time source where PDC emulator is pointing.
