SCCM 2012 Site System Roles & What is new in SCCM 2012 :

Configuration Manager uses site system roles to support management operations at each site. When you install a Configuration Manager site, some site system roles are automatically installed and assigned to the server on which Configuration Manager Setup has run successfully. One of these site system roles is the site server, which you cannot transfer to another server or remove without uninstalling the site. You can use other servers to run additional site system roles or to transfer some site system roles from the site server by installing and configuring Configuration Manager site system servers.

Each site system role supports different management functions. The site system roles that provide basic management functionality are described in the following .

Below are total available(18) site system roles in ConfigMgr 2012:

Component Server :Any server that runs the SMS Executive service. A server that runs Configuration Manager services. When you install all the site system roles except for the distribution point role, Configuration Manager automatically installs the component server.

Site Server : A computer on which you run the Configuration Manager setup program and which provides the core functionality for the site.

Site System: A server or server Share that hosts one or more site system roles for Configuration Manager site

The following site systems roles are removed:

  • The reporting point. All reports are generated by the reporting services point.
  • The PXE service point. This functionality is moved to the distribution point.
  • The server locator point. This functionality is moved to the management point.
  • The branch distribution point. Distribution points can be installed on servers or workstations that are in an Active Directory domain. The functionality of the branch distribution point is now a BranchCache setting for an application deployment type and the package deployment.

In addition, you no longer configure network load balanced (NLB) management points. This functionality is automatically provided when you install more than one management point in the site.

The following site system roles are new:

  • The Application Catalog website point and the Application Catalog web services point. These site system roles require IIS and support the new client application, Software Center.
  • The enrollment proxy point, which manages enrollment requests from mobile devices, and the enrollment point, which completes mobile device enrollment and provisions AMT-based computers. These site system roles require IIS.

There is no longer a default management point at primary sites. Instead you can install multiple management points and the client will automatically select one, based on network location and capability (HTTPS or HTTP). This behavior supports a higher number of clients in a single site and provides redundancy, which was previously obtained by using a network load balancing (NLB) cluster. When the site contains some management points that support HTTPS client connections and some management points that support HTTP client connections, the client will connect to a management point that is configured for HTTPS when the client has a valid PKI certificate.

You can also have more than one Internet-based management point in a primary site, although you can specify only one when you configure clients for Internet-based client management. When Internet-based clients communicate with the specified Internet-based management point, they will be given a list of all the Internet-based management points in the site and then select one.

At a secondary site, the management point is no longer referred to as proxy management point, and must be co-located on the secondary site server.

  1. Greetings! I know this is kind of off topic but I was wondering which
    blog platform are you using for this site? I'm getting fed up of WordPress because I've had problems with hackers
    and I'm looking at options for another platform. I would be awesome if you could point me in the direction of a good platform.

    1. there is an option which you can secure your website to hide the information to others which either either go with wordpress.com or wordpress.org but i would suggest to go with wordpress.org which provides more options.
