VMWare Server time to consider host time?

I should have quit blogging about VMWare Server quite some time ago....

But I still have a client using it.

Unfortunately, we had a time issue on a guest. It was off by enough to upset logins in a domain environment.
Turns out, even if you set the guest vm to "Time syncronization between the virtual machine and the host operating system" to be unchecked....
It still syncs at login when the host fires up the VMWare Tools...
So make sure your host os has good time and even better, monitor with Nagis / Check MK!
Here is a link http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1318
Here is the section that article above me say, oh really:
  These options do not disable one-time synchronizations done by VMware Tools for events such as tools startup, taking a snapshot,
  resuming from a snapshot, resuming from suspend, or VMotion. 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. 

Oh, and if you want to know how to install Nagios3 / CheckMK:

Here is a link to setting up a lower poll interval on w32time http://penguinpackets.com/~kelly/kblog/blog/01258144111
You will need to lower the poll interval if you have a busy VM.
