ntpd: Synchronizing with time server Failed error on VMware ESX 3.5
Login as root using ssh onto your VMware server and search for UDP port 123 to see if this port for ntp client is listed on VMware ESX server firewall: # esxcfg-firewall -q |grep -i “123″ If you see no results then you don’t have ntp port enabled on your VMware ESX port.
