This discovery method is used by Configuration Manager to search and identify Active Directory sites and subnets within an Active Directory forest.
It helps Configuration Manager understand the network topology by finding the AD sites and subnets defined in the forest.
Once discovered, ConfigMgr can use this information for things like site assignment, client location services, and content distribution optimization.
Key points:
Forest-wide discovery: Unlike Active Directory System Discovery or User Discovery which target specific containers or OUs, this method queries the whole forest for site and subnet information.
Helps ConfigMgr map network locations (subnets) to AD sites, which aids in efficient management and client site assignment.
Typically used alongside other AD discovery methods to improve accuracy of resource discovery and boundary definitions.
