TCPView into Your TCP Traffic

So I had this issue a while back where my work's domain script would change the registry value for my DHCPNodeType value. The result was that my laptop couldn't see any of my home computers or printers due to the fact it was trying to resolve the peers using WINS and not NETBIOS. A friend helped me narrow this down and we did it through a similar software package. TCPView would have been very handy as well.

"TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows."
