I'm troubleshooting some time issues in my domain and before making any big changes I want to have a thorough understanding of what's going on. I've got a few lingering questions at the moment:

  • What sources (rtc, ntp, etc.) are queried by Windows to keep time? How does this differ in a mixed Active Directory / Novell environment?
  • What is the order that each source is queried in?
  • How does Windows decide whether to act as an NTP client, peer or server?
  • In what situations will Windows update the RTC, if ever?
