Kill an application pronto - from the command line on any computer
Jeff Key talks about how to kill an application pronto. I would like to add that if you have a serious need to kill processes (Jeff's need seems to be the occasion kill), PsTools from Sysinternals has a nifty little utility called PsKill. It can kill by process ID or name (i.e., aspnet_wp is a good one for me) on a local or remote computer using your account or another that you specify. The great thing about Sysinternals freeware is that they were xcopy-deployed before it became a .NET thing. DebugView is another awesome tool, especially for remote debugging on production computers (where they disable your debugging support!).
