Fix Recommendation

From the vSphere Web Client select the ESXi Host and go to Configure >> System >> Time Configuration. Click Edit to configure the NTP service to start and stop with the host and with authoritative DoD time sources.

or

From a PowerCLI command prompt while connected to the ESXi host run the following command:

$NTPServers = "ntpserver1","ntpserver2"
Get-VMHost | Add-VMHostNTPServer $NTPServers
Get-VMHost | Get-VMHostService | Where {$_.Label -eq "NTP Daemon"} | Set-VMHostService -Policy On
Get-VMHost | Get-VMHostService | Where {$_.Label -eq "NTP Daemon"} | Start-VMHostService

Check Contents

From the vSphere Web Client select the ESXi Host and go to Configure >> System >> Time Configuration. Click Edit to verify the configured NTP servers and service startup policy.

or

From a PowerCLI command prompt while connected to the ESXi host run the following command:

Get-VMHost | Get-VMHostNTPServer
Get-VMHost | Get-VMHostService | Where {$_.Label -eq "NTP Daemon"}

If the NTP service is not configured with authoritative DoD time sources and the service is not configured to start and stop with the host and is running, this is a finding.
