Let’s Configure Active Directory System Discovery for Configuration Manager. You can discover systems and users in your network once I have a post to build New ConfigMgr Primary Server.
Active directory system and user discovery is one of the first steps you perform as part of configuring new SCCM infrastructure. Once all these users and systems are discovered by SCCM, get the ability to manage users and systems.

Introduction
ConfigMgr discovery methods find different devices on your network, devices and users from Active Directory, or users from Azure Active Directory (Azure AD).
Use AD System Discovery discovery method to search the specified Active Directory Domain Services locations for computer resources. Once the resources are discovered and created a corresponding record created in SCCM, that can be used to create collections and queries.
NOTE! – You can also install the Configuration Manager client on a discovered device by using client push installation.
Configure Active Directory System Discovery
Let’s start the Configuration Manager discovery process to manager AD system records.
- Launch Configuration Manager Console
- Navigate via \Administration\Overview\Hierarchy Configuration\Discovery Methods

- Right Click on Active Directory System Discovery
- Click on Properties

- Enable Active Directory System Discovery
- Click on * button to select the Active Directory OU or discover the systems from all active directory

- Click on BROWSE from Active Directory Container
- Select the OU from where you want to discover the computer
- Select MEMCM and Click OK to discover all the computers in the Active directory for my test lab
NOTE! – For production environment – I would recommend selecting a particular OU than entire Active Directory domain.
- Click OK to continue

- Click OK to continue to complete the SCCM configuration Active Directory System Discovery

- Select YES to continue with FULL discovery “Do you want to run FULL discovery as soon as possible.”

Confirmation | Verification
Let’s check SCCM log file called ADSYSDIS.log to confirm whether configure Active directory system discovery works fine?
Some of the important steps notified in the log file snippet below:
- Valid Search Scope Name: LDAP://DC=memcm,DC=com
- Starting the data discovery
- Full synchronization requested
- discovered object with ADsPath
- DDR was written for system ‘ADMEMCM’
- successfully completed directory search~

Results – ConfigMgr AD System Discovery
Let’s check the console whether the System or Computers records are available under ALL SYSTEMS node.
- Navigate to \Assets and Compliance\Overview\Devices\All Systems

NOTE! – Now, the system or computer records there in SCCM DB, you can install ConfigMgr Client on these computer records. ConfigMgr Client Install – Install SCCM Client Manually Using Command Line
