This blog article will explain the various discovery methods and will describe how to configure it. In the final parts, we will cover the basic SCCM configurations. SCCM discovery methods identifies computer and user resources that you can manage by using Configuration Manager. It can also discover the network infrastructure in your environment. Discovery creates a discovery data record DDR for each discovered object and stores this information in the Configuration Manager database.
When discovery of a resource is successful, discovery puts information about the resource in a file that is referred to as a discovery data record DDR. DDRs are in turn processed by site servers and entered into the Configuration Manager database where they are then replicated by database-replication with all sites. The replication makes discovery data available at each site in the hierarchy, regardless of where it was discovered or processed.
You can use discovery information to create custom queries and collections that logically group resources for management tasks such as the assignment of custom client settings and software deployments. Computers must be discovered before you can use client push installation to install the Configuration Manager client on devices.
In simple words, it means that SCCM need to discover device before it can manage them. The problem is that if you have thousand computers, it can be a fastidious process. By using Active Directory System Discovery, all your computers will be shown in the console, from there you can choose to install the client using various SCCM methods. There are 5 Types of Discovery Methods that can be configured. Active Directory System Discovery Discovers computers in your organization from specified locations in Active Directory.
In order to push the SCCM client to the computers, the resources must be discovered first. You can specify to discover only computers that have logged on to the domain in a given period of time. This option is useful to exclude obsolete computer accounts from Active Directory. You also have the option to fetch custom Active Directory Attributes. This is useful if your organization store custom information in AD.
The discovery process discovers local, global or universal security groups. When you configure the Group discovery you have the option to discover the membership of distribution groups.
With the Active Directory Group Discovery you can also discover the computers that have logged in to the domain in a given period of time. Once discovered, you can use group information for exemple to create deployment based on Active Directory groups. Be careful when configuring this method: If you discover a group that contain a computer object that is NOT discovered in Active Directory System Discovery, the computer will be discovered.
If automatic client push is enabled, this could lead to unwanted clients computers. To discover resources using this methods: Use this to discover only good records Active Directory User Discovery Discovery process discovers user accounts from specified locations in Active Directory.
This is useful if your organization store custom information in AD about your users. Once discovered, you can use group information for example to create user based deployment. On the Active Directory Attribute tab, you can select custom attributes to include during discovery This is useful if you have custom data in Active Directory that you want to use in SCCM Active Directory Forest Discovery Discovers Active Directory sites and subnets, and creates Configuration Manager boundaries for each site and subnet from the forests which have been configured for discovery.
Using this discovery method you can automatically create the Active Directory or IP subnet boundaries that are within the discovered Active Directory Forests. This is very useful if you have multiple AD Site and Subnet, instead of creating them manualy, use this method to do the job for you.
Heartbeat Discovery can force discovery of a computer as a new resource record, or can repopulate the database record of a computer that was deleted from the database. HeartBeat Discovery is enabled by default and is scheduled to run every 7 days. Network Discovery The Network Discovery searches your network infrastructure for network devices that have an IP address.
It also discovers devices that might not be found by other discovery methods. This includes printers, routers, and bridges. We never saw any customers using this method in production. Working in the industry since His specialization is designing, deploying and configuring SCCM, mass deployment of Windows operating systems, Office and Intunes deployments.
