I have a head office and remote stores.
In the head office i have my root DC. I was told to setup domains in the same forest for the remote sites. I'm looking to manage all the remote sites from head office when it comes to users/gpo/software deployment. My problem is that i'm not very familiar with the whole remote site setup. The main problem is the DNS. I have secure vpn tunnels setup between remote sites and head office. I need the domain to replicate, but when the vpn is down the remote domain will still function i guess they will only replicate once the vpn is up, that's fine with me. I need detailed instructions on how to connect the remote dns to work with my head office.
