How it works
Get-ADDomainController with -Filter * enumerates the controllers, and the projection reports each host name with its AD site, IPv4 address, operating system version, and whether that server holds a global catalog.
Adapting it
Swap -Filter * for -Discover -Service PrimaryDC when the only question is which server currently answers as PDC emulator for the domain the session is bound to.
Requirements
ActiveDirectory module.
If the result is unexpected
A domain controller is missing from the inventory.
The query may target a different domain or use credentials that cannot discover the intended controllers.
- Confirm the domain and query a known controller directly before comparing the full list.
Validate the result
The inventory matches the selected domain and identifies the server used for discovery.
Keep the check reliable
Make domain and server parameters explicit in recurring inventory jobs.
