Step by Step Guide for SCCM Secondary Site Installation

Welcome to post on step by step guide for SCCM secondary site installation. In this post we will understand the concept of secondary sites. Also we will see how to install SCCM secondary site step by step. This guide will be also added to my SCCM 2012 R2 step by step guides. Secondary sites are useful when you have remote site and you want to transfer content and client data across low-bandwidth networks. If you have got sufficient bandwidth, you can always have a distribution point for every site. When you deploy Secondary site setup also installs a management point and distribution point on secondary site server.

Concept of Secondary Sites

When you deploy configuration manager, the top site in a hierarchy will be either a primary site or a CAS. Many organizations choose to use a single primary site and later add one or more secondary sites. Secondary sites can help control bandwidth utilization by managing the flow of client information sent up the hierarchy. When you deploy secondary site you do not require a local administrator for the site. This is because you manage secondary site from CAS or primary site.

In short install the secondary site if any one of the below points are true.

  • The remote site location has more than 500 clients.
  • You need to compress traffic going to the site.
  • Need to control the upward flowing traffic.
  • Local management point need.
  • Require a local software update point.

Prerequisites for installation of Secondary site

On the secondary site server install the following features – .Net 3.5 Framework, .Net 4 Framework, Remote Differential Compression, BITS.

On the secondary site server add Primary Site server computer account to local Administrator group. Provide Secondary Site server computer account full Permissions on System Management container in AD.

Ensure the following ports are opened between the site server and remote secondary site server. TCP Port 4022 (SQL), TCP port 1433 (SQL), TCP port 135 (WMI/RPC), TCP port 445 (SMB).

Secondary sites automatically install SQL Server Express during site installation if a local instance of SQL Server is not available. Since the SQL express edition is free, go with this option.

Before you install SCCM secondary site, you could make use of prerequisite check tool. This tool checks for errors/warnings/missing prerequisites. On the primary site server, mount the configuration manager media. Run the command prompt as administrator. Change the path to Mounted Drive:\SMSSETUP\BIN\X64 folder. Run the below command

prereqchk.exe /SEC secondary_server_name_FQDN /INSTALLSQLEXPRESS /Ssbport 4022 /Sqlport 1433

To Eric D Yes. you have to. You can run this as .bat file to get it working. @echo ========= SQL Server Ports =================== @echo Enabling SQLServer default instance port 1433 netsh advfirewall firewall add rule name=”SQL Server” dir=in action=allow protocol=TCP localport=1433 @echo Enabling Dedicated Admin Connection port 1434 netsh advfirewall firewall add rule name=”SQL Admin Connection” dir=in action=allow protocol=TCP localport=1434 @echo Enabling conventional SQL Server Service Broker port 4022 netsh advfirewall firewall add rule name=”SQL Service Broker” dir=in action=allow protocol=TCP localport=4022 @echo Enabling Transact-SQL Debugger/RPC port 135 netsh advfirewall firewall add rule name=”SQL Debugger/RPC” dir=in action=allow protocol=TCP localport=135 @echo… Read more »

Hello Prajwal, I have a question: at a remote location there is a distribution point. Should I want (for a number of reasons) turn it into a secondary site, it is possible to just add the secondary site to the existing distribution point or should I remove the distribution point role, first?

Thanks in advance.

Graham Banks

Hello Roberto, I’m going through the same process, did you remove the DP in the end?

Raghu Sharma

Unfortunately no, you can’t, you have to remove DP first.

Hi Prajwal. Thanks for this guide.
I have a question: If Primary Site Server and SQL database are on different servers, does it mean that TCP Ports 4022 / 1433 must be opened between Secondary Site Server and the SQL database Server, and ports 135 / 455 between Secondary Site Server and the Primary Site Server?

Thank you
