We have a branch office that has a DC(a GC), running DNS and DHCP. In their infinite wisdom, they decided to detach their connection with our network and re-attach their previous connection to the internet(bigger pipe). Long and short of it, they don't see us and we don't see them. They are still using the DC for authentication, DNS(partially), and DHCP. The question is: What are the ramifications for our active directory, with all their objects being unavailable? Can the absence of their objects, DC being one of them, cause harm to our directory?
Thanks for any input!
