This article was previously published under Q131715
SUMMARY
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.
MORE INFORMATION
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).

  5. 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.
