It does have issues with servers with large number of connections sometimes though. I sometimes use tcpview for interactive kills but wkillcx can be used in scripts. I guess it can help you a lot on both monitoring and killing unwanted connection.

In order to close the port you could identify the process that is listening on this port and kill this process. We could not kill the process either, as to not drop other connections. What we ended up doing and was not suggested yet was to block the connection on Windows' Firewall.
