Hello !

I have tried to sett my DC to get its time from several NTP severs. I follow this answer (http://serverfault.com/questions/24298/w32time-sync-problems-for-hyper-v-guests-w32time-event-ids-38-24-29-35/24299#24299) to do it.

First I disable Time Synchronization in the Hyper-V Integration Services for each guest. Then restart the Windows Time serviceon the guest.

I had before this used this command: w32tm /config /manualpeerlist:"ntp.uio.no;timekeeper. uio.no;nissen.uio.no;0.no.pool.ntp.org;1.no.pool.ntp.org;2.no.pool.ntp.org" /syn cfromflags:manual /reliable:yes /update

And the cmd sad: The command completed successfully.

But the time was still 10 min wrong... I run w32tm again after restarted the DC without it having any effect. The w32tm /query /status still say: "Source: Local CMOS Clock"
