The Cloud Management Gateway in SCCM Current Branch allows you to manage computers on the Internet without deploying the traditional IBCM infrastructure. Microsoft have made some improvements in SCCM 1702 for the CMG regarding client registration.
This post will not go into how to set up the CMG, you can view Plan for cloud management gateway in Configuration Manager for that information.
This blog post will show you how you can use the CCMHOSTNAME property when manually installing the SCCM client to specify the Cloud Management Gateway management point. This isn’t official documentation from Microsoft, however it does work. The post assumes you have copied over a PKI certificate for the client and installed the certificate, and also copied over the SCCM client installation files.
1 – On a machine that is on the internal network with the SCCM client installed, view the LocationServices.log and search for the Internet Management Point. You can see mine below highlighted in yellow. Copy the name of the Azure Cloud Management Gateway as you will need this for the CCMHOSTNAME property when installing the client
2 – Launch a command prompt to run ccmsetup.exe and run the command ccmsetup.exe /UsePkiCert SMSSITECODE=<SiteCode> CCMHOSTNAME=<CMG copied above>
3 – Keep an eye on C:\Windows\ccmsetup\Logs\ccmsetup.log and ensure it successfully installs “CcmSetup is exiting with return code 0”. My logs in C:\Windows\CCM\Logs now indicate that the client is registered (ClientIDManagerStartup.log) and communicating with the Cloud Management Gateway (CcmMessaging.log). The machine should now appear in the ConfigMgr console. I can also see in the Configuration Manager Properties of the client that it is Internet based
After it has installed successfully, you should see it communicating and retrieving policies.
