Hi all.
I am new to windows server. I have 2 sites( site-A and site-B) and each site has 2 domain controllers.
Site-A DCs= DC-1 , DC-2
Site-B DCs= DC-3 , DC-4
I want to setup each dc as writeable dc. After installing first dc, when i add each new dc, in “Aditional options” step, ask me to choose replication from(..........) and i can choose “any domain controller” or a dc which i have previouslly installed.
In this case, Which is the best selection for intrasite and intersite?( any domain controller or a distic dc). I mean, i have to choose all replication as “any domain controller“ or atleast a ditinc DC in each site?
Best regards

    Yes, I'd expect to see them all here.

    I'd select “any domain controller“ then define sites and subnets.

    then bridgeheads will handle site to site replications.
