We want to be able to from domain > able to manage the other domain.
We currently have one domain that’s 2003 AD domain.
The domain name: fx.pop.crucial.com
(there isn’t a root AD domain called pop.crucial.com, only fx.pop.crucial.com AD domain exists).
We’re going to add another domain called ex.pop.crucial.com (the name space pop.crucial.com has to be the same for political reasons).
1. When installing the first DC for ex.pop.crucial.com domain, a) is it better to add it as a new DC in an existing forest (the forest that was created when installing fx.pop.crucial.com’s DC above) or b) is it better to install the DC as a new domain in a new forest and then manually create a two way trust afterwards with the above existing domain?
2. The both domain’s DCs will be running an AD integrated DNS. Should I create a conditional forwarding to each other’s domain on each DNS?
3. In this case, if the DC from ex) fx.pop.crucial.com goes down, would the DC in ex.pop.crucial.com take over (either a) or b) )? I’m not sure how the replication works in multiple domains.
