Incorrect; Windows XP syncs the clock using the W32Time service, which polls NTP at the interval specified in DWORD registry key HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval. You can read more about it in detail here (see section "Windows XP Professional and all versions of Windows Server 2003"): http://support.microsoft.com/kb/884776 > > BTW: My experience with VBox is that it is nice for hobby stuff, but > > not for heavy load server stuff. VMWare does a better job there. Agreed. The number of problems with VirtualBox continues to grow (you should see my Mail/sent folder sometime). I don't know or why anyone on earth would use VirtualBox with problems like what's described in this thread, combined with problems like what's described below (which TMK still hasn't been addressed): http://lists.freebsd.org/pipermail/freebsd-stable/2011-February/061642.html http://lists.freebsd.org/pipermail/freebsd-stable/2011-July/063172.html http://lists.freebsd.org/pipermail/freebsd-stable/2011-July/063221.html http://lists.freebsd.org/pipermail/freebsd-stable/2011-July/063322.html I would recommend you stick with bare metal, or use something that's at least well-established like VMware products (Workstation, for example, is actually affordable, and ESXi is free -- though there have been problems posted to the list about FreeBSD on ESXi as well). Xen gets praise here on the lists, but I haven't tried it myself. I stick with bare metal for everything, sans "tinkering around". -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
