For Windows Server 2008 or greater, this port range is 49152 to 65535 and this entire port range must be open for RPC technology to work. Select Port from the Rule Type listing. The two streams operate independently, so clients and servers can read and write in whatever order they like: for example, the server could wait to receive all the client messages before writing its responses, or it could alternately read a message then write a message, or some other. RPC provides a way to represent complex objects in computer visualization projects without relying on polygonal geometry. Within MS-NRPC, however, this is an optional feature that is turned off by simply not setting a flag in the header of a message. After the client is granted access by TCP wrappers, the NFS server refers to its configuration file, /etc/exports , to determine whether the client is allowed to access any of the exported file systems.
