Argent for Exchange and Argent for SharePoint’s “Trusted Agent” is the equivalent of a remote monitoring engine.

However the current implementation only allows Trusted Agents to be installed on the local network — (e.g. not behind a firewall, for example).

The reason is because these Trusted Agents read the work orders from the Main Engine via network shares (NOT via a TCP port)

This means the Trusted Agent currently exists for two reasons:

• Load balancing within the local network
• Executing monitoring tasks on a server that has a prerequisite that the main engine may not have (e.g. Exchange Management Shell to run some of

  the Exchange 2007 Rules)
