Method not allowed

[Luis Esteban Valencia]

Hello I got this program and this error.
Unable to complete web request. Web Exception error: Error en el servidor
remoto: (405) Método no permitido

Its supposed to send xml messages to a biztalk assembly and then it should
drop them on a folder. but I got that error.

Questions.
1. The VirtualFolder HTTPReceiver must be integrated or anonymous
authentication in IIS Manager.
2. Should I Imporsonate on the web.config.
3. Should I give any more permissions?
