Here is another good utility for troubleshooting network connections. It can also come in handy while fighting some spam and spyware infection.
TCPView for Windows v2.53 is a SysInternals tool now owned by Microsoft.
You can download the file from http://download.sysinternals.com/Files/TcpView.zip.
You can also run it directly from the website using this link http://live.sysinternals.com/Tcpview.exe.
This program shows you any networking connections in or outbound from your pc as well as what processes are attached to the connection.
It is another tool I have in my repair “bag of tricks”
Let post any comments on this or other similar programs.
