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?
