NoticeThis article applies to Windows 2000. Support for Windows 2000 ends on July 13, 2010. The Windows 2000 End-of-Support Solution Center
(http://support.microsoft.com/?scid=http%3a%2f%2fsupport.microsoft.com%2fwin2000)is a starting point for planning your migration strategy from Windows 2000. For more information see the Microsoft Support Lifecycle Policy
Windows 2000 uses a new time synchronization service to synchronize the date and time of computers running on a Windows 2000-based network. Synchronized time is critical in Window 2000 because the default authentication protocol (MIT Kerberos version 5) uses workstation time as part of the authentication ticket generation process.
The information in this article applies to Windows 2000 clients when they belong to a Windows 2000 Active Directory Domain. If the Windows 2000 clients belong to a workgroup, you must manually configure the time synchronization settings.
The Windows Time Synchronization service (W32Time) is a fully compliant implementation of the Simple Network Time Protocol (SNTP) as detailed in IETF RFC 1769.
