ESX 3.5/Windows 2003/2008 Time Sync

Hello guys,

I've read all the VM docs regards time sync but still not sure what the offical word is out there on time sync. Should VMTools be used to sync time with ESX hosts???

I would strongly recommend using an external physical time server or any other physical machine as NTP server.

Use this link if you are planning to use Windows systems http://kb.vmware.com/kb/1318

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

Yes the guest will be Windows.

There is no real mention of VMTools timesync in the docs. I have my suspicions but what are your reason for not using VM Tools to timesync in a production environment. I know some do use this method.
