Restrict user to stop a windows service

问题:

I'm involved in writing a Windows Service. Before I start writing it, I'd like to know

1. What are the points to be considered in terms of LOGIN USERS, specifically how to restrict other users from "stopping a service"?
2. What are the generic points should I consider while writing a service?
3. How can I display a warning alert once the user tries to stop the service?

Note: I am trying to write the service in C.

Thanks.

1. Normal users wont be able to stop services. It requires administration privileges.
2. You can't do anything that involves writing to the screen or reading the keyboard/mouse.
3. You will need to write an application that sits in the background (hidden window) and communicates with the service via some interprocess communication method (RPC/sockets etc). This application will receive a message from the service that displays a message box or otherwise communicates with the user.

I would try to write the code (for both service & application) in C# as most of the hard work (registering with SCM, start/stop etc) has been done for you.
