How to correctly sync time of an Hyper-V host which is member of a domain?

  • 772

There are many posts concerning issues when dealing with time synchronisation over a domain which holds virtualised PDC Emulators (see this article).

As a result our PDC Emulator time (and domain time), although configured to sync from an authoritative NTP server, was wrong because of the Hyper-V Integration services/Time synchronisation. As soon as this was disabled, the PDC emulator (and domain) time began synchronising correctly, but the Hyper-V host time kept being wrong.

I suspect the Hyper-V host (2019) is not synchronising time from the domain.

How can I ensure this?

    From an elevated command prompt on the Hyper-V host run the following:

    net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /config /syncfromflags:DOMHIER /update
net stop w32time
net start w32time
