Here is the VMware best practices for time sync.. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1318 1.) How to configure the time setting for the Windows vm server? Right now, the "Syncronize guest time withhost" is unchecked (which is default). You'll want to complete #2 below before enabling this option, but I would recommend going with this method of time sync instead of having each VM sync time with a domain controller... 2.) On the VM Host - Configuration - Time Configuration... what settings should I configure? Right now I checked to "Enable" the NTP client. In OPTIONS, which options should I pick (Start automatically... Start and stop with host.... Start and stop Manually...etc)? Typically, I set each ESXi host to sync time with a domain controller. You'll want to set it to start and stop with the host, but you'll need to set some time sync servers in options first. You can choose IPs or dns names. 3.) Related to #2, should I add the NTP source in the Options? Yes, you need to add an NTP source before you can enable it to start/stop with the host. Once you set it to sync time with a domain controller, I'd make sure your domain controller(s) is syncing time with another time source. You can find free NTP time servers on the internet, I typically go with one of these. Microsoft has one you can use as well. Here are two sites I've used before: http://www.pool.ntp.org/en/ NIST Internet Time Service Hope this helps... Ben
