[Samba] Sites And Services Setup

[James]

Hello,

     I have 3 sites with 2 DC's each. (1)-------(2)-------(3) connected 
by wan links.  I have created using ADSS tool. Subnets, Inter-Site 
Transports via. IP and 2 other sites. Left the initial site as 
Default-First-Site-Name. It appears the KCC continues to automatically 
configure replication links to all DC's in all sites. I would like to 
limit replication from Site 1 to strictly Site 2. The same with Site 3 
being restricted to replicate form site 2. What am I missing? Do I need 
to configure Bridgehead servers? Thanks.
