Run the Enterprise Vault Operations Manager Configuration utility after installing Operations Manager on a server, but only after the server has been successfully configured using the Enterprise Vault configuration wizard.
You can rerun the Operations Manager Configuration utility if the configuration fails for some reason and you need to repeat it. You can also rerun the utility if you need to change the details of the monitoring user account. In this case, be sure to rerun the utility on all servers on which Operations Manager is installed.
