Gets the number of failed Transmission Control Protocol (TCP) connection attempts.
An Int64 value that specifies the total number of failed TCP connection attempts.
IETF RFC 2012 formally defines this value as, "The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state."
