When you enter the command line from any workstation on the domain,type shutdown.exe -i This brings up a GUI for the remote shutdown, and you can do a "browse" for other machines on the domain.
You can also choose from several "reasons" for shutdown, and add your own comments.
I do have a bacth file for shutdown.exe -i, and made my own icon in MS Paint as a lightning bolt. This will also find any server or machine in the Active directory on the domain.
