Hyper-V guest dc time synchronization

Hi experts,

found out domain time +2 minutes to internet time (for examples on a mobile phone).
Out domain controllers are all virtually running on hyper-v servers.
The dcs should fetch time from NTP-servers whcih seems to work. But they also fetch the time "VM IC Time Synchronization Provider" which comes from the integration services.

So I read a technet article, which first tells us to uncheck the "time synchronization" checkbock in integration-settings.
In the same article they tell us to partially diable the "VM IC Time Synchronization Provider" via registry.

Can anybody tell me what`s the best way to disable time synchronization with the host?

I will have to change this for any dc and will have to take all the dcs down for taking effect, right?

Thanks a lot.

Best regards
Roland

Hi,

Personally I never do the registry part you mentioned, I just uncheck the "Time Synchronization" box on the Integration Services Offered settings.

You just need to do it for your PDC/Time Server if your Hyper-v hosts are also taking time from your domain, otherwise if your Hyper-V hosts are not in the Domain and/or not taking time from your time server, you will have to do it on all your VMs.

And yes, you will need to restart the affected VMs.

Hope this helps you out,

Eddie

Hi,

we changed the settings on all dcs.
Not the dcs have the correct time.
How can we force a client or a server to synchronize with the dc.
How is the intervall for synchronizing the time?
