It's a little tricky getting twisted to run as a service in twisted 1.3. A main service .exe must spawn a new python process, because twisted must initialize in the main thread, and services don't start in the main thread. Its easiest to write the service wrapper in python.

I also found its easiest to register the service, then change which account the service runs as.

You could probably choose the child python script to run as

python.exe twistd.py -f web.tap

if you know how to set up the web.tap.
