Awesome thanks guys, I'll wait for the next computer to go down then I'll report back with results!

@scottalanmiller we have an ERP system that MOST of the companies work is done in.

They could still use office and such, but without the link the ERP stuff is useless. Production could continue on paper, it would just slow down

Email isnt local either, we use cloud based email which is stemmed from the datacenter.

That is a good point thank you for mentioning that

Question: have you tried setting up the DHCP server as the time master, and having the Centos system sync time to the DHCP server (with said DHCP server syncing to NIST or whatever time source you prefer) instead of the NTP Pool? That way theoretically DHCP server and Centos should be at the same time. Just a thought.

Thanks for your support my Dear 🙂

Add-DhcpServerv4Filter is a interesting PowerShell cmdlet

Sure we do. NTG has 2 datacenter locations, with DCs in each. IT-ADMIN only has 1 datacenter location, so putting a DC at the remote site would be a good idea. If he/she had another datacenter location, it would be less of a concern.

he not she, hhhh
thanks for your suggestion, i know that the best idea is to have an additional DC in the remote location, i will try another machine and promote it in the branch office, i will not give up, because i doubt the previous ADC has something wrong in its system, if it doesn't work i will try RODC
