connections keep reappearing in AD Sites and Services
Posted on 2013-09-04
I have a domain with one domain controller at a central location running Server 2008, and several branch locations with DCs running 2008R2. Each branch is connected to the central location via relatively slow VPN links.
Sites B, C, and D are all connected to site A. Sites C and D are connected to each other, but Site B is not connected to C or D at all; they don't have VPNs set up and there's no direct connectivity.
In Active Directory Sites and Services, I've set up each site and associated the correct subnets. In Inter-Site Transports\IP, I deleted DEFAULTIPSITELINK and manually created these site links:
Site A to B
Site A to C
Site A to D
Site C to D.
My problem is that for Site B, under NTDS Settings, connections keep getting automatically generated for replication from sites C and D. This shouldn't happen, since they can't communicate with each other. I manually delete the connections, but they come back on their own.
How can I get the KCC to knock it off?
