windows service problem

[JackPhil]

i code a very simple web server with python, and i want it should run
as service on WindowsXP.

the problem is i can run the service in debug mode, and it seems works
fine(i can connect the server with browser), but when i start the
service in the services control panel, i can't connect the server, the
server seems not start, and i can't stop the service.

any advice?
