SCCM Secondary Server Installation Guide Step by Step ConfigMgr

Let’s look at the installation of Configuration Manager (a.k.a SCCM) secondary server step by step guide. More details about SCCM secondary server installation in the following sections. You can’t install a secondary server without a primary server.

Secondary sites support the maximum number of 15,000 desktops devices. I don’t like secondary servers in ConfigMgr architecture (a.k.a) design mainly because it increases the complexity of SCCM infra.

NOTE! – Install a secondary site from within the SCCM console. Secondary sites don’t support a scripted command-line installation.

Prerequisites of ConfigMgr Secondary Site

Let’s have a quick go through of new SCCM secondary server installation prerequisites before starting the installation.

NOTE! – Make sure the secondary site source files as mentioned in the following section (Source Files for Secondary Site Installation) should be copied from the primary server to the secondary server.

Server OS Requirement for Secondary Server

You can install a Secondary server on Windows Server 2012 and later operating systems. You can’t install a secondary server on Windows 10 devices at all!

Domain Controller

You can’t install a secondary server on domain controllers. Secondary site servers aren’t supported on any domain controller.

Forest Trust

The two way trust is required between the domains installed the site servers like CAS, primary, and secondary servers.

User & Computer Access Rights Requirements

The user account *SCCM Admin account* that installs the site must have the following rights.

  • Administrator on the following servers:
    • The Secondary site server.
  • Primary and SQL (?) System Accounts should be part of the local admin group of the secondary servers.
  • The computer account of the parent primary site must be an Administrator on the secondary site server.

SCCM Secondary Server Installation Guide | Step by Step | ConfigMgr
  • The ConfigMgr secondary site server must meet all prerequisite configurations.
  • More SQL related access rights are explained in the below section.

NOTE! – More details are available in Microsoft documentation here.

.net – Other Windows Server roles and feature

You need to make sure all the Windows Server roles and features related prerequisites are in place for secondary server installation. More information here.

NOTE! – .NET Framework 4.0 is installed or enabled on the Configuration Manager secondary site server. This version is required by SQL Server Express.

Secondary SQL DB Setup

Install SQL server DB for ConfigMgr | SCCM Server infrastructure. More Details “The Complete Guide for SQL 2017 Installation for SCCM.”

Firewall Ports

Install ISS, Remote Differential & BITS

NOTE! – You can ignore the warning in ConfigMgrprereq.log file similar to the following.

BITS enabled; Warning; Background Intelligent Transfer Service (BITS) is required for the management point and distribution point site system roles. BITS is not installed, IIS 6 WMI compatibility component for IIS7 is not installed on this computer or the remote IIS host, or Setup was unable to verify remote IIS settings because IIS common components were not installed on the site server computer. Also, check if IIS/BITS services are running properly. Setup cannot continue until BITS is installed and enabled in the IIS settings.

Install Remote Differential Compression

SQL Server Access – Non SQL Express Installation

This is not required if you are installing SQL express version. The following setting is only required when the secondary site uses a previously installed instance of SQL Server to host the secondary site database:

NOTE! – If you choose to have Configuration Manager install SQL Server Express as part of the secondary site installation, ensure that the computer meets the requirements to run SQL Server Express.

  • The computer account of the parent primary site must have sysadmin rights on the instance of SQL Server on the secondary site server.
SCCM Secondary Server Installation Guide | Step by Step | ConfigMgr
SCCM Secondary Server Installation Guide | Step by Step | ConfigMgr
  • The Local System (NT AUTHORITY\SYSTEM) account of the secondary site server computer must have sysadmin rights on the instance of SQL Server on the secondary site server.

NOTE! – The Security Admin rights on the instance of SQL Server on the secondary site server for NT AUTHORITY\SYSTEM is not mandatory as per Microsoft docs. However, in some scenarios, you need to provide additional permissions to local system account on the new secondary server SQL DB.

Source Files for Secondary Site Installation

I would recommend copying sources files to install a new secondary site from the primary server. Source file location is

  • Use the source files from the following location on the primary server.
    • The CD.Latest source file location includes a folder named Redist.
    • Move this Redist folder as a subfolder under the SMSSETUP folder.
  • Copy the following files from the Redist folder to the SMSSETUP\BIN\X64 folder:
    • SharedManagementObjects.msi
    • SQLSysClrTypes.msi
    • sqlncli.msi
