hyperv dc time service

Question

Hello,

on a virtualized dc server, i have the time service service disabled.

this is not a server that I have made.

the synchronize date and time option is active on the vm hyper-v.

the server is on time with the host but 6 minutes behind real time (the host also).

domain clients have a 3 to 6 minute lag with real time at the dc server.

w32tm / query / status on the host gives me cmos bios.

on the dc virtual service disabled.

I keep tabs on what to do, get the service back on track, and reconfigure the time or do that on the host.

I have never seen this case.

thank you

Assuming the PDC emulator has internet access the better option may be to turn off time sync in integration services and configure the PDCe. Many NTP sources can be found here.

Some general info

• All domain members should use NT5DS domain time.
• Desktops and member servers sync with any domain controller.
• Domain controllers sync with PDC emulator (one per domain)
• PDC emulator in child domain can sync with any domain controller in parent domain.
• PDC emulator in parent domain syncs with either a hardware clock or possibly an external source.

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:<ntp ip address> /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
then check
w32tm /query /source
w32tm /query /configuration
