Calling a Windows Service does not make any sense. Is your service actually running on your server? And your web server account probably does not have permission anyway.

Service running on server and website doesn't have permission

Why?
There is no such concept "run a service". Even if you want to start a service, this is a wrong idea. The services are designed to run permanently and communicate with other processes through their IPC interfaces.

Please see my comment to the question. Your ASP.NET does not have permissions to use the service controller? This is done for some good reasons. Normally a Web application is executed in a sandboxed environment which prevents accessing the rest of the host system. This is safety-critical architectural feature of the Web server.

The whole idea is wrong. Even though some application can start and stop a service through the service controller, this is not how the whole thing is designed. The service is really designed to be executed permanently (most usually, it is automatically started) and, very typically, its threads spend most time in a wait state, not wasting any CPU time, until a service request is received by some IPC method which supports thread blocking with wait state. This could be sending some block of data through a socket, named pipe, etc. The request wakes the thread up, the service does its work and sleeps again. That's why stopping and starting it is never needed.

The application which are started and stopped on requests are usually not services but regular applications. Such applications could be on your site, which would not cause your permission problem. Better yes, it could be just a part of you code behind of some of your pages. What, this cannot do what a service could do? But I already explained: the Web service is designed to protect its host system from your artistry on the site… So, you may have a chance to get more specific advice if you explain the ultimate purpose of you activity.
