Complete Guide to Install SCCM Software Update Point Role

This post covers the steps to install SCCM Software Update Point (SUP) role. My goal here is to cover the detailed steps to install and configure software update point role in SCCM.

A software update point (SUP) integrates with Windows Server Update Services (WSUS) to provide software updates to Configuration Manager clients.

If you decide to deploy software updates to your clients using SCCM, you must ensure the software update point role is installed and configured correctly. You can follow this guide to accomplish the task.

What is Software Update Point in Configuration Manager

A software update point is a WSUS server controlled by Configuration Manager. We know that WSUS is a standalone solution that enables the administrators to deploy the latest Microsoft product updates.

Unlike WSUS the clients do not download or install updates directly from a software update point. Instead the only data downloaded by the client from a software update point is the update metadata.

In order to deploy updates to client computers, the software update point role is required on the central administration site and on the primary sites. While the SUP role install is optional on secondary sites.

So if you have got a SCCM hierarchy consisting of CAS, Primary site and Secondary sites, you install the role on CAS first, then primary site and secondary sites.

Most organizations don’t have CAS and prefer to have a stand-alone primary site. When you have a stand-alone primary site, you must install and configure the software update point on the primary site first, and then optionally on secondary sites.

Most of all the software update point site system role must be installed on a server that has WSUS role installed. I have covered the WSUS role installation in most of my current branch baseline install guides.

For stand-alone WSUS install, check the following post WSUS installation on Windows Server 2019.

The software update point interacts with the WSUS services to configure the software update settings and to request synchronization of software updates metadata. I would recommend reading the “Plan for Software Updates” article by Microsoft.

Software Update Point Requirements

Before you install the SCCM SUP role on a Windows Server, ensure you read the below listed prerequisites.

  • Always refer this article before you install site system servers and roles on Windows Servers. This is important because the role that you intend to install must be on a supported Windows Server OS.
  • Ensure you enable .NET Framework 3.5 under Windows Server roles and features. In addition, install a supported version of the .NET Framework version 4.5 or later. Starting in version 1906, Configuration Manager supports .NET Framework 4.8.
  • Install the Windows Server Update Services on a computer before installing a software update point. This is a very important prerequisite.
  • If you plan to install both WSUS and SUP role on a distribution point server, it is supported.
  • When you install a new site, ConfigMgr automatically installs SQL Server Native Client. However the Configuration Manager doesn’t upgrade SQL Server Native Client. Make sure this component is up to date.

Tip – When you install WSUS role on Windows Server 2019, the WSUS version is 10.0.17763.1. And it’s version 10.0.14393 when you install WSUS role on Windows Server 2016.

Install SCCM Software Update Point Role

Using the below steps, install Software Update Point role in SCCM.

  • Launch the SCCM console.
  • Navigate to Administration > Overview > Site Configuration > Servers and Site System Roles.
  • Right-click the server on which you wish to install Software Update Point role and click Add Site System Roles.

On the General page, click Next.

On the Proxy page, you can specify proxy server details if you have it in your setup. Otherwise click Next.

Finally we are on the System Role Selection step. From the list of available roles, select Software Update Point. Click Next.

Install Software Update Point in Configuration Manager

Specify Software Update Point Settings

On the Specify software update point settings page, under WSUS configuration you find two options.

  • WSUS configured to use ports 80 and 443 for client communications.
  • WSUS configured to use ports 8530 and 8531 for client communications.

The WSUS upstream and downstream servers will synchronize on the port configured by the WSUS Administrator. Select the second option here because it’s a default setting for WSUS installed on Windows Server 2012 and above. The firewall on the WSUS server must be configured to allow inbound traffic on these ports.

We also see two other options :-

  • Require SSL communication to WSUS Server – With this options checked or enabled, you can use the SSL protocol to help secure the WSUS that runs on the software update point. WSUS uses SSL to authenticate client computers and downstream WSUS servers to the WSUS server.
  • Allow Configuration Manager cloud management gateway traffic – Enable this option for the software update point site system to accept CMG traffic.

Click Next.

Software Update Point proxy server settings

If you have a proxy server configured in your setup, specify the proxy server settings for SUP. The options are greyed out because you must configure the site system role to use a proxy server first.

WSUS Server Connection Account

You can configure an account to be used by the site server when it connects to WSUS that runs on the software update point. When you don’t configure this account, the Configuration Manager uses the computer account for the site server to connect to WSUS.

Click Next.

SUP Synchronization Source Settings

In this step you select a synchronization source for the software update point. In other words you define the source from where updates download.

  • Synchronize from Microsoft Update – Use this setting to synchronize software updates metadata from Microsoft Update. In case you have an upstream software update point configure, this option is unavailable. Note that this setting is available only when you configure the software update point on the top-level site.
  • Synchronize from an upstream data source location – Use this option to synchronize software updates metadata from the upstream synchronization source. If you select this option, specify a URL, such as https://WSUSServer:8531, where 8531 is the port that is used to connect to the WSUS server.
  • Do not synchronize from Microsoft Update or upstream data source – Use this option to manually synchronize software updates when the software update point at the top-level site is disconnected from the Internet.

WSUS Reporting Events

You can create WSUS reporting events on the Synchronization Source page of the wizard or on the Sync Settings tab in Software Update Point Component Properties.

  • Do not create WSUS reporting events
  • Create only WSUS status reporting events
  • Create all WSUS reporting events

Since the Configuration Manager doesn’t use these events, you can leave the default option enabled – Do not create WSUS reporting events. Click Next.

Specify Synchronization Source settings
Specify Synchronization Source settings and WSUS reporting events

SUP Synchronization Settings

You can define a synchronization schedule and configure the software updates to sync automatically. Click Enable synchronization on a schedule box and configure the sync schedule.

You can either select Simple Schedule (also known as recurring schedule) or go with a custom schedule. By default the synchronization occurs every 7 days. You can change it if required.

You can also let Configuration Manager create an alert when the synchronization fails on the site. I prefer to enable this option because I get to see an SUP sync failed alert in the Configuration Manager console.

Click Next.

Supersedence Rules

On this page you can configure the software update to expire as soon as it is superseded by a recent update. You can also set a software update to expire after specific period of time.

Starting in Configuration Manager version 1810, you can specify the supersedence rules behavior for feature updates separately from non-feature updates. This is a nice addition.

Under Supersedence behavior for updates and feature updates, you find the below options.

  • Immediately expire a superseded software update
  • Do not expire a superseded software update until the software update is superseded for specific period. When you select this option, you must specify the months to wait before a superseded software update expires. By default it is set to 3 months.

At this point, I will go with the default settings and click Next.

WSUS Maintenance Options

To automate the cleanup procedures after each synchronization, Microsoft has added some cool WSUS Maintenance options. If you are using Configuration Manager version 1906 or newer, you will find these options.

I will explain each of these options in a separate post. For now I will only list the options.

  • Decline expired updates in WSUS according to supersedence rules
  • Add non-clustered indexes to the WSUS database
  • Remove obsolete updates from the WSUS database

Since we are installing the SUP for the first time, you can leave these options unchecked. We can later revisit and enable them.

Click Next.

Configure Max Run time for Software Update Installation

Specify the maximum amount of time for a software update installation to complete. I am going to leave the values to default because they look fine to me. However you can change the values if required.

  • Maximum run time for Windows feature updates – 120 minutes
  • Maximum run time for Office 365 updates and non-feature updates for Windows – 60 minutes.

Click Next.

Configure Maximum Run Time

Software Update Content Configuration

On this page you have to select whether you want to deploy full files for approved updates or deploy both full files and express installation files.

Express installation files download quickly because of lesser size and install quickly.

I am going to select Download full files for all approved updates and click Next.

Software Update Point Classifications

When you say you deploy a software update, it is actually very broad term. This is because every software update is defined with an update classification. This helps to organize the different types of updates.

When you setup SUP, during the synchronization process, the site synchronizes the metadata for the specified classifications. To know about these software update classifications, refer this article.

Once you know what classifications you require, you can enable them under All Classifications.

Wait a minute, let me cover something very important here. When you first install the software update point on the top-level site, you must clear all of the software updates classifications.

I don’t know if this is a recommended method but believe me I do this every time I install software update point in Configuration Manager. After the initial software updates synchronization, configure the classifications from an updated list, and then re-initiate synchronization.

Click Next.

SUP Products Selection

As we didn’t select anything from All Classifications, we won’t select any of these products for now. Moreover you may not see all the products listed because we haven’t performed the initial SUP synchronization.

We will select the products once we complete the initial SUP synchronization. Click Next.

For every language, you can select the software update files and summary info to download. In this example, I will select only English language. Click Next.

On the Summary page, click Next.

Install SCCM SUP Role

Click Close on Add Site System Roles wizard Completion box. This completes the installation of Software Update point role in SCCM.

Verify Software Update Point Role Installation

The SCCM log files are the best way to find out the SUP role installation status. In my other blog I have listed the software updates related log files which you can refer during software updates troubleshooting.

In most cases the installation goes well however if it fails you must know which log file to check. The SUP log files are located under <Drive:>\Program Files\Microsoft Configuration Manager\Logs

So the first log file you must open is SUPSetup.log. Look for the line Installation was successful. With this we ensure the software update point role installation is successful in SCCM.

Perform Initial SUP Synchronization

Here is how you perform the initial software update synchronization after you install SUP role in SCCM.

  • First of all launch the SCCM console.
  • Go to Software Library > Overview > Software Updates > All Software Updates.
  • On the top ribbon, click Synchronize Software Updates.
Perform Initial SUP Synchronization
Perform Initial SUP Synchronization

On the confirmation box, click Yes.

When you run the initial SUP sync, it tries to sync categories but notice what happens. If you open wsyncmgr.log file, it tells you that Request filter does not contain any known categories or classifications. Hence sync will do nothing.

At this point, let the sync complete. If you see the line “Done synchronizing SMS with WSUS Server” it means the SUP sync is complete.

wsyncmgr.log file
wsyncmgr.log file
sync: SMS synchronizing categories	SMS_WSUS_SYNC_MANAGER

Enable SUP Classifications and Products

After the initial WSUS Sync is complete, let’s enable the classifications and products under software update point role.

In the Configuration Manager console, navigate to Administration > Overview > Site Configuration > Sites. Select the site, right click and click Configure Site Components > Software Update Point.

Software Update Point Properties
Software Update Point Properties

On the Software Update Point component properties box, select Classifications tab. Enable the ones that you require. In this example, I am selecting Critical Updates and Security Updates.

Enable SUP Classifications
Enable SUP Classifications

Next, click Products tab and select the products. In this example I am selecting Windows 10 product. Once you are done with selections, click Apply and OK.

Enable SUP Products
Enable SUP Products

After you select Classifications and Products, you must run the software update point synchronization again. Only then you will see the updates for selected products appearing in the console.

Open the wsyncmgr.log file and you will notice the updates synchronization begins. Based on the products and classifications that you select, it takes time for the process to complete.

Hello Prajwal, thank You for this guide. Just one question left: how to configure the SCCM SUP to work with WSUS located on another server? My one tries to connect to WSUS on the same server and reasonably fails.

Uttam

Hey , I have sccm 1902 , software update point component properties does not show windows 10

Dan Ceccato

Hey Prajwal,

Do you know if its possible to restore an update that’s been marked as expired? Our district is still in the midst of transitioning to Win 10 so half our fleet is still windows 7. The 2019-03 Servicing Stack Update has been marked as expired and has been removed from our SCCM library, yet its a major pre-requisite to a number of other updates. Even in our self managed WSUS, its still marked as an active update. Is there anyway to get WSUS force the update back into the SCCM Software Update list?

Thanks,
DC

Morteza

Hi Prajwal
Can the download path of updates be changed? For example, a remote storage medium or …?
This is possible in wsus in the Content section. What about sccm?

regards.

Hi Prajwal, thank you for this brilliant guide. Just so you know, your guide was highly recommended from: https://serverfault.com/questions/947975/is-it-necessary-to-separate-sccm-sup-and-wsus-roles I have a query, as I am new to SCCM: We are going to be deploying SCCM into our environment this week, we intend to use it to manage imaging and patching our Dell WYSE Windows 10 thin clients. We have built x2 servers in our domain environment to prepare for this: x1 SCCM server (Windows Server 2019, SQL Server 2016, SCCM version 1910) x1 WSUS server (Windows Server 2019) We just have x1 HQ site, both servers and all thin… Read more »

Great guide, I do have a question though, If the Primary Site with SUP is in a secure network with no internet access, is it possible to configure it to point to an upstream WSUS to not only download the catalog, but the update files as well? Do I have to configure the upstream sync in the WSUS console seperately to what is configured in SCCM for catalog sync? I can get the catalog to sync with an upstream WSUS, but when I try to configure ADRs It tries to go to the internet, I want sync the updates folder… Read more »
