Hi,

When I did a netstat -a on my windows box, I see some machine connected on TCP:1274. How do I disconnect this?

Thanks for help

Thank you, Wizmatic. Is there a way to close the connection using a DOS command or any app?

Any port above 1024 is a non reserved port. These ports are arbitrarily taken by applications when they need to create a connection.. for example, your web browser, when you read this site.. your IM client when you message a friend.. or your mail when it downloads over POP3 or uploads via SMTP.

Before you run around killing connections, you should do this:
Identify what the IP is.. you can run a whois on the IP from www.geektools.com .. you'll most likely find its something you're legitimately using.

The next step is to identify what process is actually using that socket. I recommend TCPview from www.sysinternals.com for this. It will show you the connections (like netstat output, but real time) as well as what process owns the socket. From there you can kill the connection, or even terminate the process.
