What are the requirements to configure a Stub zone?
A Stub Zone is a special type of DNS zone that contains only the essential records needed to identify the authoritative DNS servers for another zone. It’s used to forward queries to the correct DNS server without storing the full zone data.
Example:- Stub Zone Between Two Forests
Scenario:
You have two forests:
- Forest A: `corp.local`
- Forest B: `branch.local`
DNS servers in Forest A are to resolve names in Forest B without transferring the full zone data.
Steps to Configure Stub Zone in Forest A:
1. Open DNS Manager on a DNS server in Forest A.
2. Right-click Forward Lookup Zones → choose New Zone.
3. Select Stub Zone.
4. Enter the zone name: `branch.local`.
5. Add the IP address of the authoritative DNS server in Forest B.
6. Ensure that zone transfers are allowed from Forest B’s DNS server to Forest A.
Now, Forest A’s DNS server will forward queries for `branch.local` to Forest B’s DNS server using the stub zone records.
This setup is especially useful when:
Avoid full zone replication.
cross-forest authentication or certificate auto-enrollment.
Preparing for a forest trust.
