      I used to run D4 with my old XP Dell PC. I needed to have the time updated
      every 5 minutes in order to have the correct time.

      After changing to "Windows Vista" I no longer use D4. I have the operating
      system reset my clock every 4 hours. The new PC keeps very accurate time.
      (It is a Dell also but much better than the old one) The better clock
      probably not a function of the operating system???

      For information on how to set up the paramemeters using windows Vista, see
      this link...

      Vista default is 7 days. I suggest following the directions and setting the
      time sync update interval to every hour. If not often enough, then adjust as
      needed. I no longer use D4 thus one less application open!

      Works for me. XP automatic time update was a weak link, Vista much better!
