Hi all, I've a little problem with a couple of Web Service written in C#, called AuthService.asmx and CanvasService.
From my client module (window form exe written in C#) when I call AuthService.asmx all works fine
When I call CanvasService.asmx all works fine
When I call AuthService from CanvasService I get the following error


System.Web.Services.Protocols.SoapException: Server was unable to process request System.Net.WebException The underlying connection was closed An unexpected error occurred on a receive System.IO.IOException Unable to read data from the transport connection An established connection was aborted by the software in your host machine

Can someone suggest me a way to understand the problem?
I've tried to re-create web reference links in all projects and rebuild all several times but the error still the same.
Thank you in advance for your help.
Regards
Fab
