Hello Zhia,

As far as i understand it, if you have multiple dc's in an site it can 
happend that an client tries to access an dc in an different office 
subnet which will fail because of (2).
I use an setup similar to yours, one main site conneted to in my case 3 
brnaches via VPN and each one has his dedicated dc. I use different 
sites for the barnches here however.
Had to create an site and an assigned subnet before i joined an new dc 
for an subnet, which worked fine back then (~ version 4.0.3).
With that setup i only gor replication errors for objects bewteen the 
brach dc's. Decided to add vpn tunnels between the branches so each dc 
can access every other dc.
