When you shutdown a VM DC, you don't have the hardware clock keeping the system time more-or-less accurate. When you start the thing up I kinda like the idea of having vmware sort its time out long before Windows even knows what's going on, otherwise you're relying on the windows time service which starts after the OS.
Also, I'd imagine the vmware tools would be somewhat more aware of the fact that a VM guest will constantly lose small amounts of time, whereas I'm guessing the windows time service would assume that it doesn't need constant adjustments. I don't know this for sure, so I kinda get the feeling I'm going to be corrected here :) Cheers, Travis -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charlie Kaiser Sent: 21 February 2006 15:16 To: [email protected] Subject: RE: [ActiveDir] Vertual Active Directory in production enviroment ? Hi Travis. Why would you set the DC VMs to time synch with the hosts instead of an outside source?
