Windows service in Python

[Gandalf]

Can anybody tell me how to write a windows service in Python? I would 
only use file operations (maybe the logger module) and TCP/IP.
I already have my server and it runs fine both on Windows, Linux and 
FreeBSD maybe others too, who knows? :-) The only problem is
that it should be a service. It is easy to make it a service on a UNIX 
machine but I need to run as a Windows service on NT/2000/XP.
Is this possible? Can you show me a link to an example? Any help 
appreciated.

Thanks in advance,
