Win 2K8 Server - VM DC - time is off by 30 minutes

Hello - I have a virtual standalone DC (VMWare) running 2008 Server and the time is off by 30 minutes. None of the other VM's are off, and they are all running XP, and not part of the domain. That VM is basically used as a Terminal Server, nothing else. The host is a Dell box, not sure what the model is. I will check the BIOS, but I'm not at the site right now. Just wondering if there's something else I can check, as I can remote into the VM.
Any ideas? thanks!

I assume you're running ESX/i...ensure NTP is configured correctly for the hosts, and they should point to an external stratum 1 time source or your ISP's stratum 2 time source.  Then decide where to point your DC's both physical and virtual.  Personally I point all of ours to the same external stratum 1 time source.

Also note that VMware does not recommend syncing virtual DC's with your hosts using VMware Tools.

Here's a good read on this...after reviewing, pay closer attention to the 'Controlling Time Drift' section.

paulsolov - can I view the time via the vSphere client? If not, I'll have to check when I'm at the site.

yelbaglf - yes I am running ESXi.

I found this article: http://support.microsoft.com/default.aspx?scid=kb;EN-US;816042

I've never used the "fix it for me" feature. Should I give that a shot?
thanks!

I just fired up vSphere client and saw that the host time is off by 30 minutes. So I reconfigured the time via the client. Can I use a Net Time command to re-sync the DC guest with the host?
No, Right Click the VMware Tools Tooltray Icon, and select Sync Time with Host.

VMware Tools will then sync the time automtically.
Nice - thanks!
