    The dynamic RPC range that is used by the runtime coordination process which is deployed on a VM guest OS for application-aware processing (when working over the network).

    Note that Exchange 2010 or higher (in particular, Client Access) expands standard Windows dynamic RPC port range to provide a better scalability.

    For more information, see this Microsoft article.

     

    Used Ports Note

    Configuring dynamic RPC range is not required when using default Microsoft Windows firewall settings as Veeam Backup & Replication automatically creates an associated firewall rule for the runtime process during installation. When using custom firewall settings or if application-aware processing fails with the RPC function call failed error, make sure to configure dynamic RPC ports manually. For more information, see this Microsoft article.
