I was seeing these error messages in the “Application” Event log on my Publisher.
Event Type: Error
Event Source: DCOM
Event Category: None
Event ID: 10009
DCOM was unable to communicate with the computer <Computer Name> using any of the configured protocols.
These MCS servers have dual NIC’s which can be teamed. On the Publisher I had enabled the network interface that was not connected to a switch port. Once I disabled the unused interface the errors stopped immediately.
