Our DCs are virtualised within a Win 2008 R2 Hyper-V environment on a network not connected to the internet.
Does anyone have advice as to best practice for setting up time service?
Currently I manually correct the time on the PDC (virtual) and have group policy set so that all servers and computers look to this pdc to set their time.
I have disabled the Time Integration within HyperV settings - but I seem to have a problem when rebooting the physical host that the PDC is running on. Possibly because the host cannot find the DC when it first starts up, it seems to make up its own time which then pushes to the dc and all other servers.Not sure if the host is getting the time from the bios, which I do keep correcting - but seems to be trailing off quite fast.
In any event I want to prevent the PDC from changing time unless I expressly correct it - as a simple reboot of the host server means the time is changed on all desktops and servers to something up to an hour out!
Any help gratefully received
