Domain Controller - Firewall Ports
Can anyone give me some ideas on firewall ports for DCs/PCs between offices? I have configured, DC to any DC, between offices, PC <Block> remote offices, and well configured the ADSS, which is the mapped DC and Subnets to related site. But I found that PC usually go to found other DCs. I dont have idea on that and I am not able to simulate the case. Thanks for any assitance.

You can try to take a look at the below links for DC to DC communication via a firewall:

You will need to also ensure that you have proper AD site and subnet configuration. The client will look for a local DCs inside the same site based on your subnet configuration inside AD sites and services.
