How do I change the settings on a windows server 2008 box, so that the server synchronizes with time.windows.com more often?

Currently, it shows that the next synchronization time is 12 hrs from now. I want to synchronize more often, like once every couple of hours.

For a single server, change
HKLM\SYSTEM\CurrentControlSet\Services\W32Time\ TimeProviders\NtpClient\SpecialPollingInterval
to the value (in seconds) that you want the interval to be.

For multiple servers in a domain I'd set it via GPO.

The only solution that actually helped in my case (virtualized Windows Servers with no Active Directory) is described on this page: http://www.pretentiousname.com/timesync/

It's actually about running an own Scheduled Task, making sure that the Time Service is started and then calling w32tm.exe /resync.

I exported the task to XML and then import it to every new installation.

It's insane. Btw, never had this problem for Active Directory members.
