Setup is two Active Directory servers with DNS replication across two sites. For 'legacy' purposes, I need to redirect queries for the previously lone file server to each site's respective copy. Eg, 'BIGBOX' -> 192.168.100.2 for site A; 'BIGBOX' -> 192.168.200.2 for site B. Setting a CNAME record works, but only until DNS replication kicks in...
Both AD DC's use a site-specific bind9 installation either as forwarder (Windows Server 2008r2 @ site A) or bind_dlz component (Samba4 @ site B).
I believe it should be possible to rig up a 'BIGBOX.subnet.domain.com' zone on either BIND9 machine pointing to the respective file server copy. Kind of a 'split-horizon' scenario, but without views and only for one address.
If this makes sense, how would such a zone file look like (NS, A record)?
Any pointers [sic] greatly appreciated!
