Hello everyone,
Some weeks ago, I had to deploy SCOM Agent on more than 350 windows servers at the time. For that, I wrote a PowerShell Script where you just have to give a server list in input and the name of your RMS/MS . And that’s it, the script is performing the agent installation for you. A CSV file will be generated as output with the agent installation status of each servers.
Concerning the right management, you have to ensure that the Default Action Account using on the server that you will use for deploying the agents (MS normally), has administrative right on the servers that you want to add in SCOM. For that, and the duration of the deployment only, use a Domain Admin Account as the Run As Account of your MS/RMS.
The script :
