Time discrepancy between member servers and domain controllers

Hello Windows Server Experts,

I have a strange problem that I'm having a hard time with. The environment I work in has approximately 40 servers (both physical and virtual servers). I have four servers, 2 physical and 2 virtual , that the clocks get out of sync with our domain controllers by exactly 2 minutes. I have checked network connections and those look good. I have verified the virtual servers are not syncing with their hosts and not domain controllers. Any ideas of what I'm missing. The time discrepancy never grows more or less than 2 minutes.

Thanks,
Nick

Are the servers that get out of sync VM's? If so check to make sure the VM are not set to sync there time with the host. AD joined clients and servers should sync with the AD PDC server. Also on your VMware host check the date and time in the bios

I've been out sick, so I'm just getting back to this. Some of the servers are physical and some of them are virtual. We also have a few workstations that off by two minutes. Thanks for your participation in this.

On your Forest root PDC set the server to update it's time from an internet source.

w32tm /config /manualpeerlist:"ServerName" /reliable:yes /update

Your member servers & clients will pickup the new time when they are reboot or you force the time update using w32tm
