Dynamic RPC port range for Microsoft Windows 2008 and later. For more information, see this Microsoft KB article.

Note: If you use default Microsoft Windows firewall settings, you do not need to configure dynamic RPC ports. During setup, Veeam Backup & Replication automatically creates a firewall rule for the runtime process. If you use firewall settings other than default ones or application-aware processing fails with the "RPC function call failed" error, you need to configure dynamic RPC ports. For more information on how to configure RPC dynamic port allocation to work with firewalls, see this Microsoft KB article.
