Hello,

You could ask the developer of the program to add the necessary command line parameter :D


Best regards,

If you know the process name, you can kill the process using pskill from sysinternals: http://www.microsoft...tilities/PsKill.mspx - but I can't promise that the TCP connection is dropped as well.  The post above for curports does offer a close command line.  See: http://www.nirsoft.net/utils/cports.html

TCPKillNT
Quote
TCPKillNT is a TCP connection "Reset" utility for Microsoft Windows NT platforms. It has the ability to send RST packets to already established TCP connections. Quite deadly on a LAN. It is very useful for IDS kind of products which need to terminate a TCP session. Requires Winpcap and LibnetNT.
