Is it possible to 'chain' AD Domain Controllers together such that there is a different network path between each DC...
DC1(root) ------- DC2 ------ DC3 ------ DC4 ------ etc...
In the minimal diagram above:
DC1 can only contact DC2 directly but not DC3 or DC4
DC2 can contact DC1 & DC3 directly but not DC4
DC3 can contact DC2 & DC4 directly but not DC1
DC4 can only contact DC3 directly but not DC1 or DC2
Can DC's 3 & 4 function correctly like this or does each peer DC need to have direct connectivity with the forest root?
