I am unable to use the Port Scanner in order to scan the ports of a system over rhe internet. What I would like to do is to troubleshoot a computer using Telnet. In order to do this I need to establish the computer's ip address and an open port. The ip address can be located in the header of an email or by using TCPView (from www.sysinternals.com). Will someone please tell me how to use the Port Scanner in order to obtain a list of the open ports on a remote system?

Thank You!
