This service is nothing new. It's not only included in Windows XP, but also in Windows 2000, and it's simply called the "Windows Time" service. According to Microsoft: "The Windows Time Synchronization service (W32Time) is a fully compliant implementation of the Simple Network Time Protocol (SNTP) as detailed in IETF RFC 1769." Some Microsoft KB articles about the service: Q224799: Basic Operation of the Windows Time Service http://support.microsoft.com/support/kb/articles/Q224/7/99.ASP Q216734: How to Configure an Authoritative Time Server in Windows 2000 http://support.microsoft.com/support/kb/articles/Q216/7/34.ASP Q223184: Registry Entries for the W32Time Service http://support.microsoft.com/support/kb/articles/Q223/1/84.ASP If the Windows machine is part of a domain (old NT or AD), the time is synchronized with a domain controller, otherwise the time.windows.com server is simply the default SNTP server used. You can disable the Windows Time service from the Services MMC snapin, or set the preferred SNTP server(s) to something different, running the following from a command prompt: net time /setsntp:"sntp1.example.com sntp2.example.com" These servers will then turn up (delimited by spaces) in the string value "ntpserver" under the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters You can check what the service is doing by checking the Event Viewer, or running the following from a command prompt: w32tm -v D> This is good so that we do not have to grab a 3rd party app and install it, D> but what is disturbing is take a guess as to what the "default" Time Server D> that gets used??? D> time.windows.com !!! Conspiracy theories aside, it's quite nice of Microsoft to provide their own SNTP server to be bashed upon by hordes of Windows clients.
