James, If your virtualized DC runs out if time even you configured it to get the time from an external time server, but your ESX server on which it runs on is ok, than do this Tools settings only for the DC. Leave the other VMs to sync with your time master DC. It is not VMware best practices to set "Time synchronisation between the virtual machine and the ESX Server operating system" option in VMware Tools for all VMs.

I want to enable this on all of my virtual servers as doing it in this fashion seems to work more effectively than sync'ing everything from my virtualised PDCe. However, I don't fancy logging on to each one individually and checking the box....does anyone know if there is a way of automating the setting of this option? My Googling appears to be tinged with week-ending weariness....
