The purpose of the FIN ACK message in a TCP connection termination process is to acknowledge the receipt of a FIN (finish) message from the other party and signal the completion of the connection termination process.
http://support.microsoft.com/kb/923200 When the sending computer sends FIN, the state of the TCP connection is set to FIN_WAIT_2. After the TCP connection has been closed, the sending computer sends RST in order to reset the connection if the receiving computer sends any packets to the sending computer.

The TCP FIN ACK is a crucial step in ending a connection between two network devices. It signifies that one device has finished sending data and is ready to close the connection, while the other device acknowledges this request. This exchange ensures that both devices are in sync and can safely terminate the connection without any data loss or errors.
The process of a TCP server is to receive TCP connections and handling the data correctly. The letters TCP in TCP server stands for transmission control protocol.
