If you're running Windows 2000 or XP at home, it's very unlikley that you have a 'Primary Domain Controller' to give you the time of day. ;) Windows 2000 & XP has a built in "Windows Time" service that is also compatible with public SNTP Time Servers, all you need to do is configure it. I chose a local SNTP server from the list: http://support.microsoft.com/kb/262680 ``` Microsoft Windows 2000 [Version 5.00.2195] (C) Copyright 1985-2000 Microsoft Corp. C:>net time /querysntp This computer is not currently configured to use a specific SNTP server. The command completed successfully. C:>net time /setsntp:ntp0.uk.uu.net The command completed successfully. C:>net time /querysntp The current SNTP value is: ntp0.uk.uu.net The command completed successfully. C:>net stop w32time The Windows Time service is stopping. The Windows Time service was stopped successfully. C:>net start w32time The Windows Time service is starting. The Windows Time service was started successfully. C:> ``` Done! Immediately after the last line "net start w32time", I noticed my clock jumping forward a few minutes. You can see messages in the "Event Viewer" from W32Time, for example: ``` Event Type: Information Event Source: w32time Event Category: None Event ID: 593 Date: 26/07/2005 Time: 11:40:05 User: N/A Computer: LOCALHOST Description: Time service corrected the clock error by 220 seconds ```
