You can also use a custom control code to ask a "hot reload" of the config file.

See : http://msdn.microsoft.com/en-us/library/ms682108%28VS.85%29.aspx

"Range 128 to 255

The service defines the action associated with the control code. The hService handle must have the SERVICE_USER_DEFINED_CONTROL access right."

Normally, some process would need to communicate with the service to tell it to re-read its settings file and take appropriate action. This could be done through any sort of IPC mechanism, TCP, named pipe, etc.
Or... here's an idea: It could monitor for changes in its settings file. When it has been modified, it could automatically take action.
The simplest solution might be to simply stop the service and restart it. For instance, this pair of command lines would do it:
     net stop MyService
     net start MyService
