I found an interesting error, always on call 256 in an process (there can be several running at the same time, but always the 256 call from each process will fail)
We are getting Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
An error occurred while receiving the HTTP response to [uri]. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
What is can be wrong, it seems to be the client, but it is?
Could it be because any limitation in Windows 7 and Windows Server Web Edition?
I it is in my company's firewall.
Thanks for your help rene
