close a TCP/UDP port on manual detection

Is there any shell command or GUI utility to close a TCP/UDP port on
detection?

Once I detect that an unwanted TCP/UDP port is open (e.g. by using NETSTAT)
I would like to force it to close instantly... is there any way to
accomplish this?

thankx
 
Ports do not "self-exist". They exist because a program that is running has
created the ports and is listening on it. If you want the port closed
down,...then shutdown the program responsible and the port will "go away".

"TCPView.exe" (from SysInternals?) is a utility that can help you find the
progrma responsible.

Thanks for your reply!

Hmmmm...... I thought that a program (the program that "opens" the port)
could access the network through some interface provided by the OS and so it
could be possible to interact with the TCP/IP interface provided by the OS
thus closing a wanted port?

Thanks!!!
