1. The user-mode software issues a remote I/O request by calling local I/O services.
2. After some initial processing, the I/O Manager creates an I/O request packet
(IRP) and passes the request to the Windows redirector, which forwards the
IRP to the transport drivers.
3. Finally, the transport drivers process the request and place it on the network.
The reverse sequence is observed when the request reaches its destination.
