The scope of an audit store defines which audited computers send their audit data to the audit store, and which collectors are assigned to the audit store. The scope is a set of Active Directory sites and/or subnets. To configure the scope for an audit store, open its Properties page and select the Scope tab. To add a site, click Add Site and select the site from the list. To add a subnet, click Add Subnet and type a subnet address and mask.
