This article describes how to set up a Windows NT Server to act as a DomainTime Source server and enable client computers to synchronize with it.
Network administrators may establish one or more Windows NT timesourceservers as domain time standards and modify client login scripts tosynchronize workstation time to the timesource servers. Networkenvironments that require high accuracy may install the TIMESERV utility(included in the Windows NT Resource Kit). This utility synchronizes aWindows NT computer to a remote time standard through modem dial-up. Formore information about TIMESERV, refer to the Windows NT Resource KitHelp file (RKTOOLS.HLP).
Setting Up Windows NT Server as a Domain Time Source Server
WARNING: Using Registry Editor incorrectly can cause serious, system-wideproblems that may require you to reinstall Windows NT to correct them.Microsoft cannot guarantee that any problems resulting from the use ofRegistry Editor can be solved. Use this tool at your own risk.
Start the Registry Editor (REGEDT32.EXE) and locate the following Registry subkey:
Value Name: TimeSource Data Type: REG_DWORD String: 1
Choose OK and quit the Registry Editor.
Shut down and restart Windows NT.
Enabling Client Computers to Synchronize with Domain Time Source Server
For Windows NT client computers, type the following in the MS-DOSCommand Prompt or add the following to the login script:
NET TIME /DOMAIN:<domain name> /SET
For Windows or MS-DOS based client computers, such as Windows, Windowsfor Workgroups, LAN Manager for MS-DOS or Microsoft Network Client forMS-DOS, type the following in the MS-DOS command prompt or add thefollowing to the login script:
NET TIME /WORKGROUP:<domain name> /SET
NOTE: You can also synchronize all timesource computers with a mastertimesource computer using the command: NET TIME \\<computername> /SET.The master timesource computer can also be synchronized to an externaltime standard using the TIMESERV utility.
