I'm following the advice given in this article: http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(WS.10).aspx#deployment_considerations_for_virtualized_domain_controllers

However my domain is slowly losing time, its about 7 minute behind what the time servers indicate is the current time.

I have two HyperV hosts, with a DC on each one. The hosts are domain members as well.

The first HyperV host is HyperV Server 2012 R2, the DC is SBS 2011. The second HyperV host is Windows Server 2008 R2, the DC is Server 2012 (not R2).

How can I keep the domain time correct?

EDIT:

    If you followed best practices you ahve configured at least the PDC emulator to get the time from an external source. And that should distribute.

  • What are you using as an external time-source?

    run a w32tm /query /verbose on a DC that has its time off and edit your original question with that output.

  • Just to clarify: You disabled the Hyper-V Time Integration service on the VM's in question?

  • @joeqwerty Yes, I fully disabled the Time Integration for all DCs.
