I just posted a new blog entry here on the SQLMag website on how I automate the shutdown and startup of Windows services.
It's nothin' fancy, but might be useful to you.
Check it out under Blogs >> Tool Time or go directly there at http://www.sqlmag.com/blogs/tool-time.aspx.
Be sure to let me know what you think and if you have your own unique methods for automating the control of Windows services!
