If your attempting to manage time settings for many XP systems on a network, it doesn’t make a whole lot of sense to have each system contact a time server on the Internet individually. Instead, one system could be configured to contact an external SNTP server, and others on the network could be configured to contact that system instead. To accomplish this, configure one XP system to use an SNTP server via the Internet Time tab, and then create a batch file on other systems that includes the command net time \\192.168.1.2 /set /yes, with the correct IP address of the system configured to contact the SNTP server specified. Then, configure the batch file to run as often as you deem necessary using Scheduled Tasks in Control Panel. Alternatively, the NET TIME command could be added to the autoexec.bat file on each system to run automatically when Windows XP boots.
