Windows
Server includes W32Time, the Time Service tool that is required by the
Kerberos authentication protocol. The Windows Time service makes sure
that all computers in an organization that are running the Microsoft
Windows 2000 Server operating system or later versions use a common
time.
To guarantee appropriate common time usage,
the Windows Time service uses a hierarchical relationship that controls
authority, and the Windows Time service does not allow for loops. By
default, Windows-based computers use the following hierarchy:
- All client desktop computers nominate the authenticating domain controller as their in-bound time partner.
- All member servers follow the same process that client desktop computers follow.
- All
domain controllers in a domain nominate the primary domain controller
(PDC) operations master as their in-bound time partner.
- All PDC operations masters follow the hierarchy of domains in the selection of their in-bound time partner.
In
this hierarchy, the PDC operations master at the root of the forest
becomes authoritative for the organization. We highly recommend that you
configure the authoritative time server to obtain the time from a
hardware source. When you configure the authoritative time server to
sync with an Internet time source, there is no authentication. We also
recommend that you reduce your time correction settings for your servers
and stand-alone clients. These recommendations provide more accuracy
and security to your domain.
