How to Interact w/ my C# Windows Service?

Hi,

I have just created a windows service using C#. I would like to leave this service installed on a windows server and I want to be able to interact with it (call functions and store variables) remotely. I want to do this ideally through a browser using ASP or whatever. I am currently stuck on trying to decide in what direction I would like to go next. What kind of technology will allow me to remotely connect to my windows service through a browser. I would appreciate it if you guys can get me in the right direction.

Thanks in advance,
Boomba
