Need help on Time Sync

[hons]

My network have several DCs and about 200 PCs which are inside an "INTRANET" without external connection.

I need some information on how to setup the "Time Sync" for all the DCs and PCs.

Can anyone help on this???

Thanks.

By default, all PCs in a site will sync via Nt5DS time with either a local DC in their site, or the PDCE DC if it exists in their site, and DCs will try to sync with the PDCE DC. The PDCE DC can be configured to be a reliable source without having to sync to another (actual) reliable NTP server, although it would be best to at least have one machine in your intranet that is running NTP software that does sync to at least a stratum3 server on the public internet, like one from pool.ntp.org. If you can at least do that, you can find your answer here.

If you can't do that, you can set your PDCE up as an NTP server as well and make it the local time source via NTP to sync with itself, but that's a bit redundant. I strongly recommend either doing nothing (by default, the PDCE becomes the authoritative time source in this scenario), or have an actual sync'd NTP server somewhere on the intranet that the PDCE can sync with. You can find all the reg entries you need in KB223184.

Good luck .
