[VPC] Disable host time sync

I happen to have a PDC (Windows Server 2003 R2) inside a VM running on Virtual Server 2005. For testing purpose, we have to forward it’s time clock to 1 month after. To fully disable timesync feature on the VM. We have to  disable time sync feature of the OS and of the Virtual Server.

To disable time sync of Virtual Server 2005, open the Virtual Server 2005 management console, there’s a checkbox on the [Virtual Machine Additionals] tab, simply shutdown the OS, check this option and restart the VM.

To disable time sync of a PDC, which is more cpmplicate since a root PDC is also a time server for it’s AD. Follow the instruction to configure time service on the PDC.

In additional, to disable host time sync in VPC 2007, open the .vmc file via notepad, it’s a xml formatted document, add the following elements to the file or modify existing element.
