System center configuration manager 2012 R2 (Part3) Discovery

Leave a comment

After we installed our primary server in part1 and part2 we will be configuring our SCCM to be able to see our environment by Configuring Discovery and Boundaries in Configuration Manager 2012 R2, Discovery identifies computer and user resources that you can manage by using Configuration Manager, and it also discovers network infrastructure in your environment. Use the information in the following sections to help you configure discovery in System Center 2012 Configuration Manager.

clip_image00172 Active Directory Forest Discovery

 As the name suggests it discovers Active Directory sites and subnets, and then creates Configuration Manager Boundaries for each site and subnet from the forests which have been configured for discovery, with this discovery method you are able to automatically create the Active Directory or IP subnet boundaries that are within the discovered Active Directory Forests.

You can see in the below screenshot that except Heartbeat Discovery all the other discovery methods are disabled (not configured) by default.

From Administration, expand Hierarchy Configuration, Select Discovery Methods. Double click Active Directory Forest Discovery.

Check all the boxes to enable the AD Forest Discovery to create boundaries automatically along with IP address. Click on Apply. When you click on Apply, it asks you to run the full discovery as soon as possible. Click on Yes. Click on OK.

What are the Boundaries

Boundary

Is a network location on the intranet that can contain one or more devices that you want to manage. Boundaries can be an IP subnet, Active Directory site name, IPv6 Prefix, or an IP address range, and the hierarchy can include any combination of these boundary types. To use a boundary, you must add the boundary to one or more boundary groups.

Boundary groups

are collections of boundaries. By using boundary groups, clients on the intranet can find an assigned site and locate content when they have to install software, such as applications, software updates, and operating system images.

Configuring Boundaries

We have run the Active Directory Forest Discovery method we don’t need to create boundaries here, we will create a Boundary Group. Now we need to add the Boundary to the Boundary groups. In the Configuration Manager console, select Boundary Groups, right click and click on create a boundary group. Provide a name to the boundary group and click on Add.

Configure Active Directory Discovery for Computers, Users, or Groups

We can configure discovery of computers, users, or groups, by using one of the following discovery methods:

·         Active Directory System Discovery

·         Active Directory User Discovery

·         Active Directory Group Discovery

With Active Directory System Discovery we can discover the computers in the organization from specified locations in Active Directory Domain Services. In order to push the SCCM clients into the computers, the resources must be discovered first.

Right Click Active Directory System Discovery and click on properties. Click on Enable Active Directory System Discovery.

To add the Active Directory Containers click on the Orange color icon. Click on Browse and select the domain. Click OK. Click on Apply. Run the full discovery by clicking Yes. Click on OK and close the properties page.

clip_image00172 Active Directory User Discovery

This Discovery process discovers the user accounts from your Active Directory domain. You will have to specify the Active Directory container to search for the user accounts. There are some good options to discover the user accounts like the option to discover the user objects based on the attributes, recursively search AD child containers, discover objects within the AD groups.

Double click the Active Directory User Discovery, Enable the Active Directory User Discovery. select the Active Directory Container. Click on OK.

The Active Directory Group Discovery discovers the groups from the defined location in the Active Directory. The Discovery discovers all group types, and you have the option to discover the membership of distribution groups too.

To enable the Active Directory Group Discovery, Double click the Active Directory Group Discovery and check the box “Enable Active Directory Group Discovery“. Click on Add and click on Location.

Select the Active Directory Container. Click on OK.

HeartBeat Discovery

The HeartBeat Discovery runs on every Configuration Manager client and is used by Active Configuration Manager Clients to update their discovery records in the database.  The HeartBeat Discovery is enabled by default and is scheduled to run every 7 days.

Warning

The Active Directory polling by each of these discovery methods can generate significant network traffic. Consider scheduling each discovery method to run at a time when this network traffic does not adversely affect business uses of your network.
