Agent on a remote machine can be deployed either manually, through SCOM discovery, through SCCM packages, etc.
If the agent is being installed on a remote server using the SCOM discovery, then the account should be having the administrative privileges to perform the installation and the SMB ports (139 & 445) should be open between SCOM servers (gateway in terms of customer) and remote servers. Once we execute a discovery for the given set of devices, we can select the servers where all we need to install and configure the agents remotely from SCOM itself. Please be noted that whenever we push the agents from SCOM, we don’t need to configure the agents (like we will configure during manual installation) since this will be taken care by SCOM itself.
Once the agent is pushed to the remote machine, it doesn’t impact or break any other things/tasks running on the remote machine. Also wont be having any performance degradation on the target machine. But please be noted that once the installation task has been initiated, it won’t be able to cancel till it completes. But as a roll back perspective, we can uninstall the agent from “Programs and Features” control panel.
