About the service connection point in Configuration Manager
Applies to: Configuration Manager (current branch)
The service connection point is a site system role that provides several important functions for the hierarchy. Before you set up the service connection point, understand and plan for its range of uses. Planning for usage might affect how you set up this site system role:
Download updates that apply to your Configuration Manager infrastructure. Only relevant updates for your infrastructure are made available based on usage data you upload.
Upload usage data from your Configuration Manager infrastructure. You can control the level or amount of detail that you upload. For more information, see Usage data levels and settings.
Deploy a cloud management gateway in Azure
Synchronize apps from the Microsoft Store for Business and Education
Discover users and groups in Azure Active Directory (Azure AD)
Use Desktop Analytics to gain insights on Windows 10 update and app readiness
Each hierarchy supports a single instance of this role. It can only be installed at the top-tier site of your hierarchy, which is a central administration site (CAS) or stand-alone primary site. If you expand a stand-alone primary site to a larger hierarchy, uninstall this role from the primary site, and then install it at the CAS.
Modes of operation
The service connection point supports two modes of operation:
Online: The service connection point automatically checks every 24 hours for updates. It downloads new updates that are available for your current infrastructure and product version to make them available in the Configuration Manager console.
Offline: The service connection point doesn't connect to the Microsoft cloud service. To manually import available updates, use the service connection tool.
If you change between online or offline modes after you install the service connection point, restart the SMS_DMP_DOWNLOADER thread of the SMS_Executive service. Restarting this thread makes the change become effective. To restart this thread, use the Configuration Manager Service Manager.
You can also restart the SMS_Executive service for Configuration Manager, which restarts most site components. Alternatively, wait for a scheduled task like a site backup, which stops and restarts the SMS_Executive service for you.
To use the Configuration Manager Service Manager to restart the SMS_DMP_DOWNLOADER thread:
In the Configuration Manager console go to the Monitoring workspace, expand System Status, and select the Component Status node. In the ribbon, choose Start, and then select Configuration Manager Service Manager.
In the service manager navigation pane, expand the site, expand Components, and then choose the component that you want to restart: SMS_DMP_DOWNLOADER.
Go to the Component menu, and choose Query.
Confirm the current status of the component. Then go to the Component menu, and choose Stop.
Query the component again to confirm that it stopped. Then choose the Start component action to restart it.
Remote site system requirements
When you install the service connection point on a site system server that's remote from the site server, configure one of the following requirements:
The computer account of the site server must be a local admin on the computer that hosts a remote service connection point.
Set up the site system server that hosts this role with a site system installation account. The distribution manager on the site server uses the site system installation account to transfer updates from the service connection point.
Internet access requirements
If your organization restricts network communication with the internet using a firewall or proxy device, you need to allow the service connection point to access internet endpoints.
For more information, see Internet access requirements. Other Configuration Manager features may require additional endpoints from the service connection point.
These configurations apply to the server that hosts the service connection point and any firewalls between that server and the internet. Allow communication through outgoing HTTPS port TCP 443 to the internet locations.
The service connection point supports using a web proxy with or without authentication to use these locations. For more information, see Proxy server support.
If the Configuration Manager site fails to connect to required endpoints for a cloud service, it raises a critical status message ID 11488. When it can't connect to the service, the SMS_SERVICE_CONNECTOR component status changes to critical. View detailed status in the Component Status node of the Configuration Manager console.
Starting in version 2010, the service connection point validates important internet endpoints for Desktop Analytics and tenant attach. These checks help make sure that the cloud-connected services are available. It also helps you troubleshoot issues by quickly determining if network connectivity is a problem. For more information, see Validate internet access.
The specific URLs required by the service connection point vary by Configuration Manager feature:
- Updates and servicing
- Windows servicing
- Azure services
- Microsoft Store for Business
- Cloud services
- Configuration Manager console
- Desktop Analytics
- Tenant attach
- External notifications
The service connection point uses the Microsoft Intune service when it connects to
manage.microsoft.com. There's a known issue in which the Intune connector experiences connectivity issues if the Baltimore CyberTrust Root Certificate isn't installed, is expired, or is corrupted on the service connection point. For more information, see Service connection point doesn't download updates.
Validate internet access
If you use Desktop Analytics or tenant attach, starting in version 2010, the service connection point now checks important internet endpoints. These checks help make sure that the cloud-connected services are available. It also helps you troubleshoot issues by quickly determining if network connectivity is a problem.
For the list of internet endpoints, see the following sections of the Internet access requirements article:
For more details, review the EndpointConnectivityCheckWorker.log file on the service connection point.
A failure isn't always determined by the HTTP status code, but if there's network connectivity to an endpoint. The following scenarios can cause a check to fail:
Network connection timeout
Unexpected status code:
Status code Description Possible reason 407 Proxy authentication required May indicate a proxy issue 408 Request timeout May indicate a proxy issue 426 Upgrade required May indicate a TLS misconfiguration 451 Unavailable for legal reasons May indicate a proxy issue 502 Bad gateway May indicate a proxy issue 511 Network authentication required May indicate a proxy issue 598 Network read timeout error Not RFC compliant, but used by some proxy servers to indicate a network timeout 599 Network connection timeout error Not RFC compliant, but used by some proxy servers to indicate a network timeout
There are also the following status messages for the SMS_SERVICE_CONNECTOR component:
|11410||Informational||All checks are successful|
|11411||Warning||One or more non-critical failures occurred|
|11412||Error||One or more critical failures occurred|
When you run Setup to install the top-tier site of a hierarchy, you can install the service connection point.
After setup runs, or if you're reinstalling the role, use the Add Site System Roles wizard or the Create Site System Server wizard. (Only install the service connection point on the top-tier site of your hierarchy.) For more information, see Install site system roles.
Move the role
There are several scenarios in which you may need to move the service connection point to another server:
After you move the service connection point, check all site functions. For example, you may need to renew the secret key for any connections to Azure Active Directory (Azure AD) tenants. For more information, see Renew secret key.
Console notifications for the service connection point
Occasionally, the Configuration Manager console may give you a notification about your service connection point. The notification asks you to restart the SMS_EXECUTIVE service on the server that hosts the service connection point. This notification occurs because a configuration change was made by Microsoft on the services that your service connection point connects to. Features of Configuration Manager that rely on these services may not function for your site properly until the SMS_EXECUTIVE service is restarted.
To view information about uploads to Microsoft, view the Dmpuploader.log on the server that runs the service connection point. For download progress of updates, view the Dmpdownloader.log. For the complete list of logs related to the service connection point, see Log files - Service connection point.
Use the following flowcharts to understand the process flow and key log entries. This process includes update downloads and replication of updates to other sites.
