Remote Procedure Call (RPC) dynamic port allocation is used by remote administration applications such as Dynamic Host Configuration Protocol (DHCP) Manager, Windows Internet Name Service (WINS) Manager, and so on. RPC dynamic port allocation will instruct the RPC program to use a particular random port above 1024. Customers using firewalls may want to control which ports RPC is using so that their firewall router can be configured to forward only these Transmission Control Protocol (TCP) ports. Many RPC servers in Windows let you specify the server port. When you can specify a dedicated server port, you know what traffic flows between the hosts across the firewall, and you can define the that is traffic allowed much better. You can find a comprehensive list of Server ports that are used in Windows and major Microsoft products can be found in Microsoft Knowledge Base article 832017.
