Active Directory Sites And Services

We have our corporate office with 2 domain contollers and 1 offsite domain controller
A and B are at the corporate office and C is offsite. Right now thru active directory sites and services we have A replicating with B, and B replicating with C. Should this be setup so that all domain controllers replicate to eachother too?

Ideally yes so you have a fully redundant Active Directory. But it is also not a requirement either.

Seth Simmons

just to add, you could setup an additional link at a higher cost between A and C so that if the B-C link broke (server down, etc.) then C would still be able to talk directly to A

i had done that at my previous place between 4 different sites; redundant links at a higher cost and worked fine for us

Right now do you have one site in active directory or two sites. The KCC is building those connection objects for you and if replication is working fine I'd leave it as is.

Right now we have 2 sites. 1 site has DCs A and B and the other site has DC C.

Mike Kline

Then they don't all need connections to each other. As long as replication is working (repadmin or the ad replication status tool can help verify that0.

So if we were going to add a 3rd site with DC D how should the repliacation go?

Mike Kline

I'm guessing the third site will have connectivity with HQ? I'd add a site link between HQ and Site 3 and let the KCC build the connection objects.

Thanks
