How To Configure Stub Zone on Windows Server 2022?

Stub zone in Windows DNS :
is a special, read‑only zone that stores only the essential records (SOA, NS, and glue A records) needed to identify the authoritative DNS servers for another zone.
It’s mainly used to improve name resolution between separate DNS namespaces and to keep delegation information automatically updated.
What a Stub Zone Contains
A stub zone includes only three record types:

SOA record – identifies the primary authoritative server.
NS records – list the authoritative DNS servers for the target zone.
Glue A/AAAA records – IP addresses of those authoritative servers.
This makes the stub zone lightweight and automatically updated whenever the authoritative zone changes.

Why Use a Stub Zone?
Stub zones are useful when:

Two organizations merge or need cross‑namespace resolution.
You want automatic updates of authoritative DNS server info (unlike conditional forwarders).
You want to avoid manually maintaining forwarders when DNS servers change.
You want faster, more direct resolution to another domain’s authoritative servers.

👉How to Create a Stub Zone in Windows DNS

GUI Method (DNS Manager)
----------------------------------------------
👉Open DNS Manager.
👉Right‑click Forward Lookup Zones → New Zone.
👉Choose Stub Zone.
👉Select Primary or AD‑integrated (if domain‑joined).
👉Enter the zone name (e.g., corp.example.com).
👉Add the master DNS server(s) from which the stub zone will pull NS/SOA/glue records.
Finish the wizard.

PowerShell Method
------------------------------
👉Add-DnsServerStubZone -Name "corp.example.com" `
-MasterServers 10.0.0.10,10.0.0.11 `
-ZoneFile "corp.example.com.dns"
This creates a stub zone and configures the master servers that supply the authoritative records.
