Esx host not updating time ntp
If your DNS and default gateways are not configured properly then you might not be able to synchronize with the NTP server as request wont be able to reach the NTP servers.NOTE :- It takes 5-10 minutes to synchronize to internet time servers, wait before you perform any kind of troubleshooting.Time synchronization across a Windows domain is very important.If a member server's clock varies more than 5 minutes from other domain servers, Kerberos tickets will fail.Features and known issues from prior releases of v Center Configuration Manager (EMC Ionix Server Configuration Manager (SCM) 5.2 and 5.2.1) are described in the release notes for each release.The current Release Notes are posted to the VMware download Web site and the Configuresoft Customer Download page.
VCM 5.3 is the first release of VCM that provides software provisioning features that allow you to install or remove software driven from user actions in the VCM console and tied to compliance enforcement. The v Center Configuration Manager Hardware and Software Requirements Guide provides detailed system configuration information required to ensure a successful installation.Even if this synchronization is disabled, by default VMware Tools synchronizes the virtual machine’s time after a few specific events that are likely to leave the time incorrect.This one-time synchronization is done by VMware Tools for specific events such as: These events synchronize time in the guest operating system with time in the host operating system even if VMware Tools periodic time sync is disabled, so it is important to make sure that the host operating system’s time is correct.Often, the servers that run v Center are domain member computers and administrators think that since the v Center syncs time with the domain, the hosts and VMs do, too. You need to configure the v Sphere or ESX hosts to sync time from an accurate time source, otherwise the VM guests may start up with the wrong time - You may need to restart the VM guests running on that VMware host to have them sync time with the domain.The Windows Time service will not correct the time on the VMs if it varies too much from domain time.
