Within the config you cannot select rpc endpoint mapper, and subsequently all the dynamic ports. A given RPC program usually has different port number bindings on different machines, so there is no way to directly broadcast to all of these programs. Since the RPC endpoints are assigned ports when the services start, these ports are dynamically assigned from 49152 to 65535. If you enable subnets to reach the RPC Endpoint Mapper but not the dynamic port 28 แถว · There is a RPC (a RPC's Endpoint Mapper component) vulnerability in Windows NT where a malformed request to port 135 could cause denial of service (DoS).
