manipulate a service on aother computer using asp.net

[JasmineT]

i need to start and stop a service on a machine on the network using the ServiceController class. i can do it on the local machine using a code like this to test a service public void testServices(Object src, EventArgs e)
{
/*System.ServiceProcess.ServiceController myController = new System.ServiceProcess.ServiceController("iisadmin"
myController.MachineName="myMachineName";
if(myController.CanStop)
{

Response.Write(myController.DisplayName+" can be stopped."
}
else
{

Response.Write(myController.DisplayName+" cannot stop."
}*/

}

but if i specify another machine name it says access denied.
what can i do?
