Prerequisites for Windows Client Deployment in Configuration Manager – Prerequisites for
Computer Clients Installation Method Dependencies Client push installation:
Client push installation accounts are used to connect to computers to install the client and are
specified on the Accounts tab of the Client Push Installation Properties dialog box. The account must
be a member of the local administrators group on the destination computer.
If you do not specify a client push installation account, the site server computer account will be
used. The computer on which you are installing the client must have been discovered by at least one
System
Center 2012 Configuration Manager discovery method.
The computer has an ADMIN$ share.
Enable client push installation to assigned resources must be selected in the Client Push Installation
Properties dialog box if you want to automatically push the System Center 2012 Configuration
Manager client to discovered resources.
The client computer must be able to contact a distribution point or a management point to
download the supporting files.
You must have the following security permissions to install the Configuration Manager client by
using client push:
To configure the Client Push Installation account: Modify and Read permission for the Site object.
To use client push to install the client to collections, devices and queries: Modify Resource and Read
permission for the Collection object.
The Infrastructure Administrator security role includes the required permissions to manage client
push installation.

Active Directory Forest Discovery and Publishing in Configuration Manager 2012 Beta 2
Forest Discovery and Publishing Overview
To improve manageability of an ever-changing network environment, Active Directory Forest
Discovery is added in Configuration Manager 2012 Beta 2. With it, Configuration Manager can
discover Active Directory forests, their domains, AD Sites and IP subnets. Because domain users (or
domain computer accounts) have permission to query forest relationships, Active Directory Forest
Discovery can return information about other forests and their trust direction. The system can
programmatically connect to all the forests and build a complete mapping of the corporate
environment. It can also cross forest boundaries using specific credentials for each forest regardless
of the trust type. The information obtained through Active Directory Forest Discovery can be directly
exported as boundaries or boundary groups. Changes to discovered data are updated dynamically
and aged out from the database if no longer present in Active Directory Domain Services. The

discovered data is also used when clients request a management point or distribution point to
ensure they receive the best possible site system.

Introduction to Client Deployment in Configuration Manager – Deploying the Configuration Manager
Client to Windows-Based Computers
The following table lists the various methods that you can use to install the Configuration Manager
client software on computers:
Client push installation – Automatically installs the client to assigned resources and manually installs
the client to resources that are not assigned.
Software update point installation – Installs the client by using the Configuration Manager software
updates feature.
Group Policy installation – Installs the client by using Windows Group Policy.
Logon script installation – Installs the client by using a logon script.
Manual installation – Manually installs the client software.
Upgrade installation by using application management – Upgrades clients to a newer version by
using Configuration Manager application management. You can also use Configuration Manager
2007 software distribution to upgrade clients to System Center 2012 Configuration Manager.
Automatic client upgrade
Client imaging – Prestages the client installation in an operating system image.
