We have a VCenter with ESXi Hosts Version 5.1, Our Domain Controller is sitting In one of the ESXi Host and the host NTP settings is pointing to that Domain Controller which is sitting in the same host.
all other ESXi hosts are also pointing to that DC as NTP server. All host are in the same cluster and our email servers are also in the same cluster and they are windows and linux.
Now we faced an issue on our Email messages which are showing wrong data and time ! What could be the reason(s) of this issue ? and what is the best practice(s) of NTP scenario in ESXi environment?
Thank You
