Discovery requires some careful planning and an understanding for what kinds of objects are discovered by a particular method. If you don't need a certain kind of object to be discovered, don't enable that discovery method.
For example, if you can't think of a reason that you need to know Active Directory group information from within SCCM, don't enable that discovery method until you need it. In most cases, one of the first discovery methods that you'll enable is the Active Directory System Discovery method.
As the name implies, this method discovers computer objects in Active Directory along with some additional information, such as the operating system version, IP address, Active Directory Organization Unit, and the last login timestamp.
Delta discovery is a method by which SCCM rescans previously scanned areas and identifies any resources that may have been added since the previous discovery process. Delta discovery runs every 5 minutes, but this interval is configurable. Every discovery option carries with it its own configuration parameters, so explore a bit to see what's out there. Lowering the heartbeat discovery interval to every 4 hours or so should be fine though.
Not that this is a really old post and there are actually a couple of additional items included in a heartbeat DDR as of ConfigMgr You can either wait for the next Heartbeat Discovery cycle to run, or you can hurry things along by selecting the Discovery Data Collection Cycle on the client Configuration Manager Properties: Actions tab, and click OK.
This will be the case if the client cannot communicate with its management point. No to the question, but it sounds like something good to do and blog about. Thanks for this write up Jason, really useful. Egil Lazarus Professional. What is a discovery method? Discovery learning takes place in problem solving situations where the learner draws on his own experience and prior knowledge and is a method of instruction through which students interact with their environment by exploring and manipulating objects, wrestling with questions and controversies, or performing.
Khadijatou Fargallo Professional. All Configuration Manager site systems must be members of a supported Active Directory domain. Configuration Manager client computers can be domain members or workgroup members. Saidia Tillmans Explainer. The data discovery record DDR , in Configuration Manager , specifies the resource type, the discovery process, the site that discovered the resource, and the resource properties. Configuration Manager provides six library functions that you use to create your own DDRs.

Active Directory is a directory service created by Microsoft for Windows domain networks. Server computers that run Active Directory are called domain controllers. Vergil Matiebel Explainer.
Hardware Inventory Cycle collects information such as available disk space, processor type, and operating system about each computer. This is a part of SCCM inventory functionality. Verlene Arimon Pundit. What is SCCM client? The domain and forest can be in any supported Active Directory mode. The account that you assign to each location instance must have Read access permission to the specified Active Directory locations.
Discovery searches the specified locations for objects and then tries to collect information about those objects. A DDR is created when sufficient information about a resource can be identified.
The required information varies depending on the discovery method that is being used. If you configure the same discovery method to run at different Configuration Manager sites to take advantage of querying local Active Directory servers, you can configure each site with a unique set of discovery options. Because discovery data is shared with each site in the hierarchy, avoid overlap between these configurations to efficiently discover each resource a single time.
For smaller environments, consider running each discovery method at only one site in your hierarchy. This configuration reduces administrative overhead and the potential for multiple discovery actions to rediscover the same resources. When you minimize the number of sites that run discovery, you reduce the overall network bandwidth that discovery uses. You can also reduce the overall number of DDRs that are created and must be processed by your site servers.
Many of the discovery method configurations are self-explanatory. Use the following sections for more information about the discovery options that might require additional information before you configure them. Filter stale computer records by domain logon. Filter stale records by computer password. Search customized Active Directory attributes. Delta Discovery is not an independent discovery method but an option available for the applicable discovery methods.
Delta Discovery searches specific Active Directory attributes for changes that were made since the last full discovery cycle of the applicable discovery method. The attribute changes are submitted to the Configuration Manager database to update the discovery record of the resource.
By default, Delta Discovery runs on a five-minute cycle. This schedule is much more frequent than the typical schedule for a full discovery cycle. This frequent cycle is possible because Delta Discovery uses fewer site server and network resources than a full discovery cycle does. When you use Delta Discovery, you can reduce the frequency of the full discovery cycle for that discovery method. Although Delta Discovery can detect new resources and changes to group membership, it cannot detect when a resource has been deleted from Active Directory.
You configure Delta Discovery on the Polling Schedule tab in the properties for each discovery method. You can configure discovery to exclude computers with a stale computer record. This exclusion is based on the last domain logon of the computer. When this option is enabled, Active Directory System Discovery evaluates each computer that it identifies.
Active Directory Group Discovery evaluates each computer that is a member of a group that is discovered. When you're configuring the time after the last logon that you want to use for this setting, consider the interval for replication between domain controllers. Choose to Only discover computers that have logged on to a domain in a given period of time.
When you configure this filter and Filter stale records by computer password , discovery excludes computers that meet the criteria of either filter. This exclusion is based on the last computer account password update by the computer. When you're configuring this option, consider the interval for updates to this attribute. Also consider the replication interval between domain controllers. Choose to Only discover computers that have updated their computer account password in a given period of time.
When you configure this filter and Filter stale records by domain logon , discovery excludes computers that meet the criteria of either filter.
Each discovery method supports a unique list of Active Directory attributes that can be discovered.

Caution When you uncheck the option to publish a site to an Active Directory forest, all previously published information for that site, including available site system roles, is removed from Active Directory. Caution When you configure a discovery scope, choose only the groups that you must discover. Note Before you can create collections that are based on extended Active Directory attributes, and to ensure accurate discovery results for computers and users, run Active Directory System Discovery or Active Directory User Discovery, depending on what you want to discover.
Note Even when Heartbeat Discovery is disabled, DDRs are still created and submitted for active mobile device clients. Note Complex networks and low-bandwidth connections can cause Network Discovery to run slowly and generate significant network traffic. Note Network Discovery runs in the context of the computer account of the site server that runs discovery. Note Subnet configurations do not limit the objects that the Domains discovery option discovers.
Warning Each increase to the number of router hops can significantly increase the number of discoverable resources and increase the network bandwidth that Network Discovery uses.
