Synching VMWare tools inside Guest to ESX host

Does anyone know which registry flag inside Windows(2k or 2k3) gets set when you check this box inside the Guest on VMware tools option? I ask because we are looking at way of scripting this setting to change multiple VM's at once instead of logging into each VM, opening VMware tools, and then checking the box.

Is the entire environment Windows based? Best practice for time sync with Linux hosts is not to use this option:http://kb.vmware.com/kb/1006427

In my experience, using NTP instead of the guest time sync option gives better results especially for time sensitive software. More information about time keeping available here: http://www.vmware.com/pdf/vmware_timekeeping.pdf

Hope this helps! === If you find this information useful, please award points for "correct" or "helpful". ===

I believe the recommended method is still to allow Windows to manage time for guests.

We do the following:

1. Windows Guests > Domain controller (PDC Emulator) > internal NTP server > external NTP server

2. Linux Guests >Synchronize Guest time with host.

3. ESX hosts > Internal NTP server > external NTP server

4. Domain Contoller (PDC Emulator) > internal NTP server
