Reboot webservice

[lorenzo.viscanti]

I'd like to create a server monitoring software.
My Winform application should request a page from my webserver and then
wait for the response. If the server is slow or not responding the
monitoring application should reboot the server via a webservice. Can I
call shutdown with the appropriate parameters from a webservice
executing shutdown.exe with administrator privileges. Is that a
suitable solution or maybe I can find better solutions?
Thanks
Lorenzo
