Configuring Discovery and Boundaries in Configuration Manager 2012 R2
Prajwal Desai
In this post we will see the steps for configuring discovery and boundaries in configuration manager 2012 R2. In my previous deployment
series of SCCM 2012 and SCCM 2012 SP1 we have seen much about the discovery methods and boundaries, this post is no different when
it comes to configuring discovery and boundaries in configuration manager 2012 R2. We will begin with discovery methods available in
configuration manager 2012 R2.
So what are discovery methods in configuration manager 2012 ? In simple terms when you have resources in your company and to gather
the resource information, configuration manager 2012 R2 makes use of methods called discovery methods. Configuration Manager 2012 R2
uses a variety of discovery methods to gather resource information and each of the discovery methods gathers information about different
objects. Lets see one by one..
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.
Launch the System Center 2012 Configuration Manager R2 Console. On the left pane select the Administration, expand Hierarchy
Configuration, Select Discovery Methods. On the right pane double click  Active Directory Forest Discovery . Check all the boxes to
enable the AD Forest Discovery. With this all the Active Directory site boundaries are created automatically along with IP address
boundaries. 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.
Active Directory Group Discovery  The Active Directory Group Discovery discovers the groups from the defined location in the Active
Directory. The Discovery Process discovers local, global, and universal security groups, the membership within these 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.
To enable the Active Directory Group Discovery, Double click the Active Directory Group Discovery and check the box which says
 Enable Active Directory Group Discovery . Once you do that at the bottom you must add the Groups or the Location. Click on Add and
click on Location.
Click Browse to specify the location. Select the Active Directory Container. In this example I have selected the Domain
PRAJWAL.LOCAL. 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.
Active Directory System Discovery  If you want to discover the computers in your organization from specified locations in Active Directory
Domain Services then we use Active Directory System Discovery. In order to push the SCCM clients into the computers, the resources must
be discovered first. There is an option to discover the computers that have logged on to a domain in given period of time, this way you won t
discover obsolete computer accounts from the Active Directory.
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.
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.
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 records (Discovery Data Records) are sent to the management point in
specified duration of time. 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. Note that the 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 can
search the domains, SNMP devices and DHCP servers to find the resources. It also discovers devices that might not be found by other
discovery methods. This includes printers, routers, and bridges. In this post we will not configure the Network Discovery method as its not
required here.
Concept Of Boundaries  A 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.
Note
When we run the Active Directory Forest Discovery, the boundaries are discovered automatically.
Since we have run the Active Directory Forest Discovery method we need not create a boundary 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.
On the Add Boundaries window select the boundary, in our case there is only one discovered boundary and that is the Default-First-Site-
Name. Click on Apply.
Click on References tab, check Use this Boundary group for site assignment. To add the site system servers, click Add and select the
Site System Server. Click on OK.
