I am trying to enable-storagecopy for a scr so it can provide DR across a single forest with three domains. Basically I want the SCR to sit in my DR domain, but provide SCR functions for the two other domains in the same forest. My environment is Exchange 2007SP2 on 2003 SVR. One parent domain and two child domains. The scr sits in one of the child domains. How can I implement the SCR to function across the forest?
