How to reset W32Time to sync time with the domain

Created: 2009-12-13

Computers no longer synchronize time from the domain correctly.



Many computers in the domain have been configured to manually sync with an incorrect NTP server.



Windows 2000

Set time source to domain (set type=NT5DS)

w32tm /config /computer:<computer> /syncfromflags:DOMHIER


To get W32Time to recognize the changes and sync time with the Domain, Stop and Start the service

SC \\<computer> stop W32Time

SC \\<computer> start W32Time


Windows 2003

Set time source to domain (set type=NT5DS) and update configuration

w32tm /config /computer:<computer> /syncfromflags:DOMHIER /Update


Sync with the domain time source

w32tm /resync /computer:<computer> /nowait /rediscover


Use the following batch file to correct multiple computers quickly.
