    1 Supports a pre-defined three- or four-tier hierarchy, but members of the intermediate tiers are Win2000 DCs that serve the time. They are not true Slaves because they do not take over for the Master automatically, replicate its settings, or have redundancy checks and tighter sync requirements than clients.
    2 If PCAnywhere, Terminal Services, or other remote-control software is installed, pretty much anything can be installed remotely. However, Domain Time II has native support for click-and-install without having to view the remote computer's desktop or install remote-control software first.
    3 Error information is available in the event log
    4 Supports NT5DC-based discovery, but not DHCP or other mechanisms

    More info on Windows Time/W32Time

    "W32Time meets the requirements specified by the Kerberos authentication protocol to provide clock values that are 'loosely synchronized' across a network. This service is not designed for use by applications that require greater precision." -- From The Windows Time Service, Microsoft, April 2001. This white paper provides some of the best documentation available on the philosophy, goals, and implementation of Windows Time.

    Article Q246145 explains about the "other W32Time" product from Microsoft. Officially called "W32Time Network Time Service for Windows NT 4.0," and documented in w32time.doc, the other W32Time is a cross between an early version of Windows Time and a late version of TimeServ, and is part of the NT4 Resource Kit. When we talk about W32Time and Windows Time on this page, we are referring to the Windows 2000/XP/2003/Vista/2008 product, not the earlier W32Time.
