How to Configure SCCM Active Directory System Discovery

Let’s Configure SCCM Active Directory System Discovery. 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 are some of the first steps you perform to configure the new SCCM infrastructure. Once SCCM discovers all these users and systems, gets the ability to manage users and systems.

The SCCM AD system discovery is a must for proper management of Windows 11 or Windows 10 devices using ConfigMgr. Using the AD system discovery you can also create SCCM Collections based on Active Directory OU.

What is SCCM Discovery?

You use one or more discovery methods in SCCM to find device and user resources that you want to manage. There are several different methods to discover users and resources from your network parameter. I recommend using Active Directory as your source for SCCM discovery.

SCCM discovery methods find different devices on your network, devices, and users from AD, or users from Azure AD). I don’t recommend using network discovery. Heartbeat discovery is switched ON by default. I don’t recommend disabling heartbeat discovery.

When an SCCM discovery method successfully finds information about a resource, it puts that information into a file called a discovery data record (DDR). That file is then processed by a primary or CAS site. Processing of a DDR creates a new record in the site database for newly discovered resources, or updates existing records with new information.

There are some prerequisites that the SCCM server will check before creating DDR for each of the discovered objects. One of them is a valid DNS record for the device object if it’s a device resource.

How to Configure SCCM Active Directory System Discovery

ConfigMgr discovery methods find different devices on your network, devices, and users from Active Directory or users from Azure Active Directory (Azure AD).

Use the 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 is 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 manage AD system records.

As part of AD system discovery, you will need to make sure that there is a valid DNS record for all the devices discovered from AD. Otherwise, SCCM won’t create device records for those discovered systems from AD.

Launch Configuration Manager Console. Navigate via \Administration\Overview\Hierarchy Configuration\Discovery Methods.

  1. We recently may have had a password change. but for system discovery, we get this in the logs.

    ISTR0=”LDAP://DC=AIIG,DC=LOCAL” ISTR1=”The user name or password is incorrect.~~” ISTR2=”” ISTR3=”” ISTR4=”” ISTR5=”” ISTR6=”” ISTR7=”” ISTR8=”” ISTR9=”” NUMATTRS=0 LE=0X0 $$

    I am thinking the password had been changed by Thycotic. Is there a password for this I can update inside configuration manager or do we need to just ensure the correct password exists in AD. We are leveraging a service account to impersonate a user. Doesn’t appear to be permission related but rather AD account access. It’s the area where it says Active Directory Discovery Account, Specify an account.

    Thank you.

    • Chris – As per the logs LDAP://DC=MEMCM,DC=COM always use LDAP. But if LDAP is not reachable I don’t know whether SCCM will try to use LDAPS or not. I never tested this scenario. So Ican’t confirm.
