We have EMC vnx block device and want to setup NTP. I do not know much about the AD. As I know, the end users' PCs get time from DC. The VNX is not part of the AD. We can set up the storage to use authentication or just use time server's ip to sync the time. Do we need any special setup on the DC to allow the storage to sync the time, in otherword use the DC as the time server?
