Here is what I have, 1-Virtual w2008r2 DC running on a Solaris box. The DC does not have internet access. For testing and other things I have to Pause the DC and when I un-pause it the time is no longer synced to the Solaris machine (CMOS). If I reboot the DC it will re-sync but I need to be able to re-sync without rebooting. Is there a setting I can change to tell the DC to re-sync to CMOS every 4 hours or something like that?

Have you tried this: W32tm http://technet.microsoft.com/en-us/library/bb491016.aspx w32tm /resyncDave Guenthner [MSFT] This posting is provided "AS IS" with no warranties, and confers no rights. http://blogs.technet.com/b/davguents_blog

I was hoping there was something that was not manual so if I forget to re-sync there is no errors and it will re-sync itself.

Answer found, I set a scheduled task to run a batch file with w32tm /resync every 1 hour.
