It's old news that Sysinternals was bought by Microsoft, swallowing up all of the wonderful utilities they developed. That being said, there is still some useful stuff that was done by SysInternals that we haven't previously covered, so I thought I'd bring one that was useful to me this week to your attention.

I had a problem with a piece of client / server software that was occurring due to too many TCP connections to the server application, but I couldn't determine where those connections were coming from. TCPView monitors all incoming TCP connections and tells you what process they are connecting to, where they are coming from, and what ports are being used. It took me all of about 10 seconds to deduce my problem.

So if you're having TCP/IP troubles, TCPView is a utility that should definitely be in your toolbox.
