Conditional forwarder in AD does not replicate to branch DNS server

Scenario

Most servers resolve a partner namespace correctly, but the branch DNS server never receives the forwarder.

Check the replication scope chosen when the forwarder was created.
Verify the branch DNS server is participating in the relevant partition.
Manually confirm the forwarder state on each DNS server rather than trusting one console.
Document the intended replication scope for future cross-domain resolution changes.

Capture the exact scope of impact, confirm which dependency failed first, and document whether the issue reflects broader domain or server drift.
