Uses pslist from the open source pstools suite from
http://www.sysinternals.com to produce a hash containing current process data.
Takes a set of key,value pairs. Currently accepts 'process' and 'machine' keys. Will extend with additional pslist options at a later date. NOTE, leading \\ on machine name is optional, and process name should not have an extension.
There probably is a better way to do this, but this tool works on local and remote machines and its really easy to use...
;-)
Or maybe that isnt the best excuse?
