Active Directory Delta discovery in Configuration Manager 2007 R3 lets you improve the performance of resource discovery by periodically scanning Active Directory for only new or changed resources. Delta discovery does not replace other Configuration Manager 2007 discovery methods. Because it only finds new or modified resources in Active Directory, it must be used together with a discovery method that performs a full synchronization with Active Directory. Use the following procedure to configure delta discovery in Configuration Manager 2007 R3.
|If you configure Configuration Manager 2007 R3 Delta Discovery, do not configure the full discovery polling schedule to be less than the default value of once every 24 hours.|
|The information in this topic applies only to Configuration Manager 2007 R3.|
