Vmware ESXi 5.1 NTP and Windows Domain Time synchronization
We have a Windows Domain , all servers are virtualized running on VMware ESXi 5.1 .
Each Virtual Guest is configured to receive time from the host configured through edit settings VMware Tools "Syncronize guest time with host"
I understand now that this could be bad for a domain controller, what is my best way to synchronize time ?
Also each of my ESXi host computers are configured to receive time from NTP servers (192.43.244.18 and 69.36.240.252). In Vsphere Client NTP client is running yet my 6 host machines do not have the same time some are off by more than a minute. How do I properly configure NTP and make sure it is working ?
I have Windows guests Server 2003 / 2008 and 2012 . Where should they be getting time ? from the DC's ? how do I force this to work ?
Thanks for your input.

As of now all my servers time is in sync, I mainly followed Sandeshdubey especially the straight forward commands that were posted. I still need to take care of my VMware host servers but for now I am ok.
I have four domain controllers in my organization that each now gets its time from an external source (time.windows.com 0x9) . Which I believe is just a Microsoft Default time source.
I have two Domain controllers at my main site and then at two remote sites I have one domain controller in each.
Should any of my domain controllers be getting time from another domain controller or is it ok to have them all access the same external time source ?
should I change the time source from the default (time.windows.com ? If I should change is there a particular NTP server I should be pointing at ?
