Windows NT/2000 does not come with a command-line 'kill' utility. You can get one in the Windows NT or Win2K Resource Kit, but the kit's utility can only terminate processes on the local computer. PsKill is a kill utility that not only does what the Resource Kit's version does, but can also kill processes on remote systems. You don't even have to install a client on the target computer to use PsKill to terminate a remote process.

Running PsKill with a process ID directs it to kill the process of that ID on the local computer. If you specify a process name PsKill will kill all processes that have that name.

usage: pskill [- ] [-t] [\\computer [-u username] [-p password]] <process name | process id>
