Symptoms

Consider the following scenario:

  • You have a Windows Embedded Compact 7-based device that is running a Transmission Control Protocol (TCP) server application.

  • You have another device that is running a TCP client application.

  • A socket connection is closed by the TCP server application.


In this scenario, the server sends a TCP reset (RST) packet instead of the expected TCP FIN packet to the client. Additionally, this may cause a socket error (SocketException) on the client device.

Note A typical TCP session teardown should consist of the server and client exchanging TCP FIN packets.

Cause

This issue occurs because the TCP/IP protocol driver in Windows Embedded Compact 7 does not perform correctly. Therefore, a RST packet is forced to be sent instead of the expected TCP FIN packet.
