I need to deploy the oomads.msi to all my Domain Controllers where the SCOM Agents were manually installed, can you provide me with the command line for installing this, so we can use Confin Manager to deploy this to all of the agents?

Hi,

OOMADS is the Active Directory Helper Object for SCOM. It is only needed on Domain Controllers.

For more information, please review the link below:

"If an agent is manually deployed to a domain controller and an Active Directory management pack is later deployed, errors might occur during deployment of the management pack. To prevent errors from occurring before deploying the Active Directory management pack, or to recover from errors that might have already occurred, you need to deploy the Active Directory management pack helper object by running the file OomADs.msi on the affected domain controller. The file OomADs.msi is on the computer that is hosting the agent at C:\Program Files\System Center Operations Manager\Agent\HelperObjects. After an agent has been manually deployed to a domain controller, locate OomADs.msi and double-click the file to install the Active Directory Management Pack helper object. The Active Directory Management Pack helper object is automatically installed when the agent is deployed using the Discovery Wizard."

Msiexec (command-line options)
