Want to know what processes are running on a remote host on your domain? First, find your way to the command prompt (START -> RUN -> cmd)
tasklist -s hostname
Something look suspicious - a process either from an application the user should not be running, a frozen app or a piece of malware doing it's business?
taskkill /S hostname /IM badprocess.exe
I find these two utils to be extremely useful and present a method to rapidly determine what is happening on a remote host and allowing admins to kill processes without requiring user intervention.
There are numerous additional switches for these utils giving them an impressive array of abilities, definitely something worth having in your IT toolbox.
