Windows Services

Question

Hi all, I'm looking to buld a program that acts as a Windows Service which runs in the background on a Windows Machine. I have Visual Studio .Net 2003 and I see that under the "File>New>Project" heading I can create a C# Windows Service. Most experience I have in C# is in ASP.Net and so i've never written a windows service before. Is there a good set of tutorials or example code that show me how to build/test/deploy a basic windows service in C#? Many Thanks
