How do I force sync the time on Windows Workstation or Server

A computer that is a member of a domain is configured by default to synchronize from the domain hierarchy, manually-specified synchronization is most useful for the forest root of the domain or for computers that are not joined to a domain.

How to resolve incorrect time with Windows Domain Controller

Many registry entries for the Windows Time service are the same as the Group Policy setting of the same name. The Group Policy settings correspond to the registry entries of the same name located in:

Configure DC to synchronize time with external NTP server - Active

Using a GPO is always better to automate as much as possible (and of course in case we had to transfer the PDC role to another DC):

You can also use the continental zones (For example europe, north-america, oceania or ), and a country zone (like in Switzerland) - for all these zones, you can again use the 5, 6 or 7 prefixes, like . Note, however, that the country zone might not exist for your country, or might contain only one or two timeservers.

or, is it better to create a new GPO, and then add the “DomainRole = 5 ” filter ?
how do i make sure my DC’s sync from my PDC ? i am asking cause i have DC’s out of sync by 7 mins…
Thanks

i understand the concept of DC’s talking to PDC, talking to external NTP
but…is there a technical reason, not to sync all DC’s directly with external NTP servers ?
“All non-PDC domain controllers should be set to NT5DS (domain hierarchy)”

Additionally, using w87tm /resync /rediscover will also force redetection of network resourced before resynchronization.

As many of you that follow my blog know that I have blogged about the Time Service in the past. The original blog can be found here. However, the blog has so much information in it, you may have got lost trying to figure out exactly what to do. In this blog, I’ve condensed it and made it much easier to read by offering the steps as a pseudo flowchart. I hope you find it useful.

All above ideas have been tried but did not help. The original problem still exists: The computer did not resync because the required time change was too big.
