I have 3 sites A, B, and C. The subnets are configured correctly on each site.
Site A is headquarters. Site B and C are branch offices, and IP traffic is not routable between them. Each of them is only routable to Site A.
All sites are members of DEFAULTIPSITELINK which has a cost of 200. I have also created two Site Links (A-B and A-C), each with a cost of 100.
KCC is incorrectly telling Site B to replicate from Site C, and isn't telling it to replicate to anywhere (seen when I right-click on the NTDS Settings object and go to Properties>Connections). What's the problem here?
