DC time is not in synch with radio controlled clock.

Hi

We use windiows 2008/XP/windows7.
In our network  our PCs time dosent match with the radio controlled clock which are around our organisation , there is 7 minutes difference. I dont know which is our time server ,
will my GC be the time server ? How do i find my time server and change the time matching to the radio controlled clock.

Thanks

The AD Server that holds the PDC Emulator role is the time server.

DC1 holds the PDC , so If i change the time on the DC1 clock, will the time synch throught the network pcs.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Yes the machines should sync, Matt has a great article you might want to look up

But you should sync DC1 with an exact time source first.

I  changed the time on the DC1  but the time has not synched with other servers. Do i need to execute any commands for the time to get synched with other servers and clients

So the DC is OK?

Clients can be configured using w32tm /resync command as described here

Because GPO take some time, you may want to use gpupdate /force on workstations to test it.



Synchronize the Time Server for the Domain Controller with an External Source
