SNS ProTip for ePO: MA 5.0 requires the System Event Notification service to be started

Version 1

    After you upgrade the McAfee Agent to version 5.0, updates may fail with the following error:

    network is down, update from remote site can't be done.

    MA 5.0 requires that the Windows System Event Notification service is running to validate the logged on user account. If this service has been stopped, the validation will fail and updates will fail with this error.
