Does Arc GIS 10.1 have a toolbox or a python script that allows to start and stop service via arc catalog?
Just in case anyone runs up against this
If you're looking for something simple and out of the box for ArcCatalog, you can simply make a GIS Server connection to your ArcGIS Server machine with a publisher or administrator type connection and start and easily stop services; no need for Python or an extra toolbox (although those tools are great).

If you do find you want something to put into a Python script, Kevin Hibma published some nice Python snippets on GitHub for administering ArcGIS Server.
