We have all muttered the words "Where is <fill in the blank> when you need it?"  A lot of times that blank is filled with the name of a SysInternals utility like Process Explorer or TCPView.  Well never utter those words again thanks to http://live.sysinternals.com :)  Here you will find a list of all the SysInternals tools ready to download.  Or if you don't want to download it to all your PCs just run the command from a command line to the remote server and run the tools that way :)

It takes about a minute for the app to load and when you close it, the app is gone.  This is definitely one to remember :)
